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

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

CNC Machining Material

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.

CNC Machining Tips: Why should you go for Flat Bottom Tools?

by | Feb 5, 2018 | CNC Machine Tools, CNC Machining, CNC Machining Guides

Flat Bottom Tools

Proper tooling is the most important part of every machining process. We need to have specific functioning milling tools if we want to develop milling parts. Same goes for all other operations. Think of it as cooking; one cannot choose potatoes as the main ingredient when making an apple pie. Yep, this analogy is not far from reality.

So we have different tools for different operations in a CNC machining shop. We might reuse some particularly reusable tools, replace the old types with advanced ones, but that’s about it. True, we focus on quality and durability, something that’ll extend its working capability (and less wear and tear). But, did you ever give a thought to tool shape?

If you didn’t, we’ll tell you why you should pay attention to your tool shapes. Let’s get to the BOTTOM of the CNC machine tools world!

Benefits of Flat Bottom Tools:

At Machining Design, we work with a plethora of tools but flat bottom tools have definitely won our hearts (and infrastructure) over. Here’s a list of reasons why we would suggest it to you as well:

1. Lower Machining Costs

As CNC’rs, we’re all aware that machining is not cheap. Add in tool maintenance and replacement costs, and it’s going to cost us more than ever. While we cannot cut on labor and operational costs, we can definitely save some using the flat bottom tools.

Now, how do they make that possible?

For one, they eliminate the extra run-time by fitting exactly where they are required. Due to their shape, they are often sturdier when compared to traditional machining tools. Carbide fit flat bottom tools beat every other tool in terms of durability. Imagine the amount of money you’ll save!

2. They are more functional

There is a list of drilling operations where these flat bottom tools play the role of a hero. Take thin plate drilling for example. When performing this operation, regular tools often face irregularities due to pushing materials through the exit hole. This derails us from achieving the desired perfection in the drilled holes. Flat bottom drills are extremely beneficial here as due to their general geometry they even downward forces. Hence, more clean surfaces.

3. They don’t create burrs

Unlike traditional tools, using flat bottom drilling tools helps us avoid unexpected (and undesired) burrs on the other side of the material. Make way for straighter and regular holes.

4. Is fit even for angular functions

Flat bottom drills are perfect for irregular surfaces due to their geometry, especially if it’s required to perform angular or tilted operations.

5. It’s stable

When countering with a half hole drilling, flat bottom drilling is proven to extremely beneficial. This is because due to the lack of material on both sides of the drill, any other machining tool may walk to the side of the material, creating an extremely undesirable situation. A flat bottom drill works closely on the entire cutting geometry, making it perfect for drilling half holes even on the edge of the material.

Working with flat bottom CNC tools definitely, make our lives (and machining process) easier. It’s easy to keep, light on pockets and DURABLE. Now, ain’t this what all of us need in our CNC machine shop?
