A Quick Guide To Understanding 5-Axis CNC Machining

by admin | Nov 30, 2020 | 5-Axis CNC Machining, CNC Machining

Ages ago, hammer and chisel were the perfect tools for creating different objects. Centuries later, handheld machines were invented, which made machining easier. But that was too time consuming and needed excessive manual labour. But don’t worry, you have our 5-axis CNC machining guide to help you understand.

Soon, computerized technology infused with machining to offer advanced computer numerical control machines (CNC machines). A program would control the tools’ movements on the blocks. It took care of the rotation of the cutter as well as the turning of the block of material.

Initially, they had just one or two axes moving along the X and Y-axis. But soon, 3-Axis CNC machines came forward that allowed the cutter to move even longitudinally along the Z-axis. And as technology advanced, machines came with five axes to cover all the five sides of a product for building all types of parts, be it simple or complex, without any additional setup.

Understanding 5-Axis CNC Machining

In the simplest terms, 5-Axis CNC machining means using machines controlled by computer numerical programs to build machined parts. These machines have cutting tools closer to the surface of the block that needs to be machined and move along five axes. In addition to the manipulation along three regular axes, five-axis machining chooses from the three rotational axes and offers a more robust mechanism for crafting specific angles and complex parts. The intricacy and precision obtained with 5-axis machining are unmatched, which makes it great for industries requiring to build complex machine parts.

Advantages Of 5-Axis CNC Machining

Most CNC machine shops now have 5-Axis CNC machines to deliver error-free products at a quicker pace. Installing these machines may be expensive, but the endless benefits they offer compel people to utilize them for producing new CNC machined parts. Here are some of the advantages of using 5-Axis CNC machining over the earlier way of machining.

Unmatched Accuracy & Precision For All Parts

One of the most significant advantages of five-axis CNC machining is the precision it can offer for all types of parts. Whether it is a complicated part, tilted surface, or a specific angle, machinists vow on 5-axis CNC machine type to get the precision and accuracy they desire. It reduces the chances of error and offers higher quality workpieces with precision accuracies.

Easier Machining Of Complex Shapes

Even the most experienced machinists cannot cut intricate shapes with just three axes of the earlier machines. To get undercutting or to reach specific angles of a workpiece, one needed additional setups or complete casting earlier. With the five axes machining in the 5-Axis machines, it becomes easier to reach any specific angle, machine arcs, and cut complicated shapes with ease.

Minimized Need For Setup Change

Several machine parts are impossible to cut with just three axes movement. They require additional setup. A 5-Axis CNC machine already has the five axes that are necessary to cut all five sides of the material to create the piece without the need to change the setup. It even helps in reducing the errors otherwise caused due to working on multiple arrangements.

Increased Life Of Tool

The length of the cutting tool is shorter in 5-axis machining as the machine head can be much closer to the cutter’s surface. With higher proximity, the speed issue gets resolved, and one can achieve more cutting speed. This process also minimizes the vibrations and helps the tool last much longer without breaking. It even controls the chip load, which leads to fewer collisions.

Decreased Collisions

Another advantage of a 5-Axis CNC machine is that it decreases the chances of collisions. With this CNC machine, one can easily tilt the cutting tool to reach specific angles. This tilting mechanism prevents any risk of collision between the surface and the cutting tool.

Reduced Lead Time

Efficiency is the reason why most people prefer 5-Axis CNC machining now. It lowers the overall lead time due to many reasons. One does not need to change the setup repeatedly. There are minimum manual changes and very few fixtures. With a single push setup or a Done-In-One setup, this reduces the overall time in finishing.

When To Use Of 5-Axis CNC Machining

CNC machining is used to cut different machined products used across various industry verticals like military, aerospace, electronics, construction, transportation, and many more. But with 3-Axis CNC machining already assisting in making many parts, why and when should one use 5-Axis machines for machining. Let’s find out.

To Machine Complicated 3D Shapes

Machining complex 3D shapes aren’t easy. One needed separated casting to machine such parts. And such casting might take months to finalize. But with the CNC machining tool, one can efficiently build these parts in a short time. The movement of the machine along the five axes allows precision on all sides without additional fixtures. No matter how complex the part, CNC machining can perfect it quickly.

To Machine Tilted Surfaces

CNC machining is perfect for machining parts that have tilted surfaces. With a movement along the five axes, 5-axis CNC machining allows drilling of surfaces with impossible geometry. The axes can reach the irregular surfaces that are tilted to offer perfection on the surface. Tapping, boring, milling, reaming, drilling, and other operations of machining on titled surfaces is much more convenient with a machine with five axes.

To Machine All Sides With Specific Angles

Industries like automotive, aerospace, medical, etc., have many parts with unusual shapes that need a specialized casting to get specific angles. Reaching the complex surfaces having distinct angles is impossible with a 3-axis CNC machining. A five-axis CNC machining tool can access all five faces of the part to machine any specific angle of the machined part.

To Machine Flexible Outputs Quickly

When it comes to machining the different types of outputs, five-axis CNC machining offers the flexibility of diverse engineering solutions without consuming much time. While most of the manufacturers show interest in low volume machining of repeated pieces, manufacturers with five-axis machining can take up high volume orders and even change the fast changes in the products. One can reprogram the machine to create a different product within a few hours.

Benefits of Custom Machined Parts for Business Success

by admin | Jan 22, 2020 | CNC Machined Parts, CNC Machining, Custom Machined Parts

Custom machined parts are manufactured through the process of machining. Machining is a manufacturing process that involves the processing of a work-piece into a part of the desired shape and size by removing material through the use of machine tools. Work-pieces that are machined are made up of materials such as metals, plastics, rubbers, etc. In this blog, we’ll cover the benefits of custom machined parts.

Metal machined parts provide a common example of a machining process. Making plastic machined parts is a very different process than metal machining. For machinists, working with different materials means facing different challenges, which requires the selection of different tools, parameters and techniques.

To get high-quality machined parts, a business can take the services of a CNC machine shop that has vast experience in machining. Custom machined parts offer many benefits such as –

Client’s Requirements Are Fully Met

Customized parts made through the process of machining fully meet the requirements of a business. They are manufactured according to the exact specifications given by a client to a machine shop. An expert machine shop can easily manufacture custom parts having complex shapes.

Extreme Accuracy

Machined parts manufactured using CNC technology are highly accurate in size and shape. All CNC machined parts are highly reliable because of the three characteristics of machining accuracy inherent in CNC technology. These are extreme dimensional, positional and shape accuracy.

Machinists make sure that the machining tolerance is within the allowable range and the highest level of precision is obtained. Tolerance is defined as the acceptable range of a dimension of a part determined by the engineers. The geometry of a part and the type of material that the part is made up of greatly affect tolerance.

Targeting a tighter tolerance can lead to additional costs due to greater production of scrap, additional fixtures, and the use of advanced measurement tools. To minimize this cost, machinists apply tight tolerances only to critical areas. By making use of CNC machines, tight tolerances can be easily obtained. High machining accuracy and highly-skilled machinists help in creating precisely machined parts that fully serve the desired purpose.

Save Time In Getting Obsolete And Unique Parts

By getting parts that have been machined according to their exact requirements, businesses are saved from wasting time in finding ready-made parts that are not being currently manufactured and are even the old stock is not available.
Businesses may also require customized parts when they have to complete a project with quick turn-around time. When the time is less, it is easier to get custom parts than to search for required parts in the market.

It may also be the case that a business may require some unique parts for certain projects that are not available in the manufacturers’ catalogs. If a business lacks resources, which are unique parts in this case, to carry out these special projects, its clients will turn to its competitor and will probably not return back even in the distant future.

In this case, also, custom parts come to the rescue. By getting custom parts, a business can go ahead and grab these special projects, and earn clients for life. For any project, when parts are available to businesses in time, their business schedule is not delayed. They can readily put these parts to work.

Get Identical Parts Easily

If more custom parts are required by a business, a CNC machine shop can readily provide them. This is because the design is stored on a computer. New parts that are manufactured are identical to the previous batch of parts. This is quite beneficial for manufacturing businesses, for example, if some of the machines of a manufacturer have stopped working and require steel parts to function again, then the custom steel parts that are identical to the previously used steel parts can be readily obtained.

Difficult-to-Process Materials Can Be Used

Some materials cannot be machined easily. For example, plastic, bronze, stainless steel, etc. require sophisticated CNC machining equipment. These materials cannot be just run through standard equipment and processes to get the desired results.
To get machined parts made of these materials, a business can contact an expert custom machine shop that uses specialized equipment to work on difficult-to-process materials.

Custom Parts Can Be Made From Existing Parts

A business may be having a large number of parts that it thinks are of no use. These parts can be modified and customized to bring them into some other use. For example, the parts of discarded machines can be altered and put to use in other machines that need those parts. This saves a lot of time and money for a business.

Streamlined Production

When a business has a tie-up with the manufacturer of custom parts, it does not have to rely on suppliers of ready-made parts. Custom parts are available whenever they are required. So, the production process of business works in a streamlined way as it does not suffer because of the unavailability of parts. With an efficient production process, a business gets the benefit of faster turn-around time.

Moreover, if in case, a business wants some last-minute changes in the parts, these changes can be easily incorporated in the custom parts by a machine shop.

Wide Application

CNC machined parts find use in a large number of industries including automotive, robotics, oil and gas, defense, mining, medical, electronics, etc. As these parts entail extreme accuracy, they are used in highly sensitive fields like defense, aerospace and aeronautics.

It becomes clear from the above discussion that there are plenty of benefits of custom machined parts to businesses. When businesses get parts that fully meet their specifications and are highly accurate, their production process becomes more efficient and they achieve a competitive edge.

Looking to Hire a CNC Machine Shop? Consider these points.

by admin | Feb 21, 2019 | CNC Machine Shop, CNC Machining

Choosing a suitable CNC machine shop can be a daunting task, especially if you’ve not done it before. It’s not just the matter of who delivers the best; the selection process also involves hiring a shop that delivers exactly what you want, faster.

Plus, there are hundreds of CNC machine shops littered across the continent – which could further complicate the entire hiring process. While initial research like references and testimonials might help, there is a lot that is needed to judge a machine shop’s performance.

If you are confused about what to look for in a precision machine shop, here are a few tips to save the day.

Hiring a Precision CNC Machine Shop: A Checklist for Entrepreneurs

Here is a list of the things that can make your CNC machine shop hunt easier.

● ISO Certification
You can begin the search by filtering out the shops with ISO Certification. The quality management label simply states your shop is equipped enough to provide you the quality machined parts you are looking for.

● Experience
Next comes the relevant experience the shop comes with. While machining startups are great on their own and could definitely meet your expectations, you might be looking for machinists or shops that have relatively greater experience working with the same industry domain as yours. Chances are they have already delivered order types and sizes similar to your requirement.

● Machining Capabilities
Machine shops that come with extensive engineering, design, and manufacturing capabilities are always safe to hire. This way you can ensure they’ll be equipped to resolve any technical or product-based limitations that might arise during the machining and manufacturing process. This also guarantees you’ll receive your order on time if all goes well.

● Variety of Equipment
A machine shop, however small, comes with solid numbers of equipment. They may not be the latest ones – in case of shops that are just starting or the ones on the stage of obsoletion. But, there are many that boast new-age cutting tools and machining equipment. You may choose them solely based on the order size and the precision needed.

● Offers Prototypes/Sample pieces
Product sampling is very crucial when dealing with large-scale production. However, there are many shops still that don’t offer sample manufactured pieces or prototypes of the design, which might cause production delays and dissatisfaction. Simply eliminate these types of shops from your CNC hunt.

● Customer Services and Support
CNC machining and manufacturing is more than just shaping raw materials into precision CNC machined parts; it’s also about how the shop deals with the customer requirements. What is the process they follow? Are they transparent in their approach? What is their workforce like? How do they deal with customer queries? In short, acute customer services is crucial in every industry, including in the CNC environment.

Things To Remember Before You Place An Order

So, you have shortlisted a CNC machine shop you deem fit for your requirement. Next comes actually placing an order with them. Wait…

Before you click on the ‘Request A Quote’ button, be sure to check everything. What is the quantity you looking for and can your shop help you with it? And most importantly, what is your requirement, exactly? You don’t want to cause production delays due to material or tolerance shortcomings, do you?

● Do you have alternatives for the material type you’ve selected?
It’s possible the shop cannot fetch CNC machining material you’ve chosen on-time. Or it could be very expensive, thereby, increasing the production cost. Anyway, having an alternative always helps in long-run.

● Are you specific with your tolerances?
You need to specify accurate measurements for precision and quality purposes, obviously.

● Do you know how the product will be developed?
This is considering you’ve done the custom part design yourself. Not considering how it will be developed while designing can lead to an increase in production costs.

Following the tips mentioned above can help you experience smooth and super-productive CNC machining!

Understanding CNC Swiss Screw Machine And Its Functions

by admin | Oct 26, 2018 | CNC Machining, Screw Machining

The world of Computer Numerical Control (CNC) is extensive. Precision machining is at an all-time high. We get introduced to a new functionality every other week, thanks to all the advancements happening in the tech space. Hand-held lathe gave way to automated lathes, and in another few decades, we’ll have AI directed lathes (those days aren’t far, folks!).

In this post, we’ll be discussing one such innovative offering to the CNC world – Swiss Screw machines. Powerful counterparts that take care of smaller and much complex CNC machined parts, so you can use up your lathes for much larger and extensive parts.

What is a CNC Swiss Screw Machine?

Originally from Switzerland, Swiss screw machines can be best described as a type of automated lathe capable of handling both CNC turning and milling.

The concept of Swiss Screw Machines is nothing new – it was first used in the 1800s, the collet chuck getting patented in the 19th century (1870s). 1960 saw Swiss screw machines gaining its momentum. The first CNC Swiss Screw machine was introduced in the late 1970s, and a decade later, they found their niche in the electronics industry. This machine type is also popular amongst Swiss watchmakers.

Swiss Screw machines are much sophisticated now. Improved designs, servomotors and CNC controls, have given today’s Swiss machines and operators much more liberty to produce highly-precise and complex parts faster, better. They are now widely used in preparing CNC machined parts for medical and aerospace applications – industries that cannot afford imprecise components.

Swiss screw machines are designed to handle both turning and milling, which enables us to produce cent percent perfection in one sitting. In this machine type, the workpiece moves in place of the cutting tool. This process is quite similar to conventional lathe – just, unlike lathe, Swiss lathe have a flexible headstock that moves back and forth (z-direction) along with the bar.

Advantages of Swiss Screw Machines

Swiss Screw machines have a lot to offer, apart from its ability to produce much smaller machined parts. This machine type drives all of its benefits out of its tools, uniquely placed geometry, and mechanics.

Listing a few outstanding ones below:

They have a very compact design – with all their parts (tools included) placed in proximity. This reduces the chip-to-chip time from one tool to another to a mere second or less.
Operation time in a Swiss machine is relatively lower than its lathe counterpart. They are flexible enough to perform several operations at one time with as many as five tools working together.
Swiss Screw machines have this extensive tool zone that can hold up to 20 tools. This number may vary depending on the machine type. The high-end machines may also contain tool changers.
They boast perfect surface finish, eliminating the need for an extra involving it.
Swiss Scre machines are fit to perform every other secondary operation – milling, drilling, sawing and what not.
Setup time is relatively shorter in case of Swiss Screw machines.
Fast cycle times and flexibility without compromising quality.

Materials 101: Entrepreneur’s guide to selecting the Right CNC Machining Material

by admin | Jul 24, 2018 | CNC Machining, CNC Machining Guides

Right materials make the best applications.

Material selection is a crucial step to get your CNC project right. Think of it as assembling a Subway meal based on your diet plan; you add meats if your diet chart asks for more protein, and greens for a vitamin fulfill. Similarly, selected materials must cover your design prerequisites— hardness, rigidity, thermal stability, and chemical resistance just to name a few. And your budget as well, of course.

Material characteristics are especially important when you require high precision CNC machined parts with complex designs. For instance: amorphous materials like metallic glass and polymers generally hold tighter tolerances than, say, aluminum.

In the following article, we will elaborate more on material types, their characteristics, tips and guidelines on choosing the right materials, and more. Let’s start with the basic: the material selection process.

CNC Materials Selection Process
If you’ve decided to jump the CNC machining wagon, have a valid prototype handy and your budget figured out, it’s time to select the best suitable materials for your project. The basic three steps to material selection are:

Step 1. Define your material requirements: Based on your design, make a high-level list of material prerequisites. Do you need a malleability? Or perhaps a sturdier material? Laser polishing for a surface finish? Consider all the mechanical, physical, environmental, and budget factors.

Step 2. Pin down qualified materials: Identify potential candidates that fulfill your material requirements. Notice, we’re are focusing on ‘candidates’ not ‘candidate’. There’s a solid reason behind it. Have a look:

Here’s what Ronald E. Giachetti, of National Institute of Standards and Technology, wrote in his paper on Manufacturing Process and Material Selection During Conceptual Design:

“The material and manufacturing process selection is performed early in the product development process. At this stage, it is inappropriate to select a single material or process without evaluating all the alternatives. The selection of sets of possible candidate materials and processes allow for greater flexibility in the product development process. The more alternatives, the greater the manufacturing flexibility.”

Hack: Make sure you approach readily available materials— it’ll help cut costs and efforts.

Step 3. Now, select the most appropriate material: The third step is the final showdown: choosing the material with maximum functionality in minimum costs. Or, the materials that check most on your prerequisites list.

In the next section, we will talk about the most popular materials and their properties.
