CNC machining is a necessity for various industries as they need high-quality CNC machined parts to produce quality products. CNC machining is synonymous with precision, and it is what most of the manufacturing industries know. 

The CNC machined parts should meet the desired standards of the industry and also meet the customer demands. So, the equipment needs to be precise and on-point. If they do not get produced according to the specifications, it can cause unexpected problems. 

Manufacturers know the importance of quality parts in a dedicated time. Failure to comply with the standards will result in loss of business. Here are the tips that will help to produce quality CNC machined parts


#1. Knowing CNC machine shop requirements 

The machine shop owners need to understand that they are going with the part with the intention of manufacturing. Machinists need to be aware of the possibility of the production and where they will produce their equipment. They need to know the complexity of the parts, the materials to get machined, the cutting tools you’ll require, and levels of precision in producing the parts. Therefore, you need a reliable CNC machine shop that’ll meet your needs. 

Once you have chosen the machine shop you want to work. Try and get information about the CNC machining prototypes and part capabilities. 


#2. Automate the process with CNC controls 

Machinists know that computer systems control the process in CNC machines. There are several cases when certain operations of the production can get automated to overcome unproductive times. 

The identical parts can get machined with higher and constant accuracy levels. The repeat orders can get set up in shorter times, and the orders get easily slotted into the production schedule. 


#3. Modify design with machine software

The next step is to review your design, and this stage is one of the most important if you begin with production. A simple change in design can help you save plenty of money. Professional CNC manufacturing in Canada has specially designed software in their machines helping to control various parameters, and designs, and providing reports and alerts to the machinists. 

The software helps the machinist to seamless the machining processes. And take proper actions to ensure that the quality of the machined part is not compromised. 


#4. CNC programming 

The final result after the design is the 3-D model that represents all the tolerances and dimensions. The majority of the CNC machine tools use a programming language called G-code. The machinists need to choose which surface on the CAD model should get machined, and the CAM system will generate the code itself. 

The process is complex as you need to take care of tolerances, geometry, and materials to generate the ideal program. You need to hire a good machine shop, and the professionals will help you move on to the processes quickly. 


#5. CNC machine setup 

Once the program is ready, the next step is to set the part. A basic CNC machine setup consists of the following considerations: 

  • Part orientation: The machinist needs to design the part orientations to remove all the excess material. 
  • Part clamping: There are a lot of different types of fixtures to clamp the part. We advise using standard tooling sets of jigs and fixtures. 
  • Coordinate zero: Once the part gets clamped, the machine tool must know where the zero coordinates are present. The piece can get adjusted manually, or you can buy an indicator. 
  • Loading the cutting tools: Lastly is the cutting tool setup. Position all the tools you use in your NC program in the slots. The machinist needs to insert the dimensions of the tool.

#6. Choose the ideal cutting tools and holders 

Use the right cutting tools and recommend cutting settings to achieve the quality of the machined parts you desire. The machinist can fine-tune the cutting parameters to achieve the desired finish. 

Avoid using any blunt tools, wrong dimension tools, or tools not suitable for machined materials. If the machinist keeps on using irregular tools, it can result in rough edges, and burn marks on the finished machined parts. 

Also, avoiding the same tool for roughing and finishing in series production runs results in lower quality finishing and higher wear and cost. 


#7. Manage the manufacturing environment 

The machine shop owners should stay away from external sources of debris and pollution. These can create effects during machining resulting in improper finishing and costly damage to the machines. 

Some of the examples include: 

  • Dust from grinding or worse from nearby foundries. 
  • Ongoing welding operations nearby CNC machines. 
  • Shock waves get created by stamping machines or presses. 


#8. Hire a professional CNC machine shop 

The experience of CNC machinists plays a crucial role in producing quality products. We at MDA have skilled experts with manufacturing knowledge and are capable of working around client requirements. 

Whether the client requires simple machined parts in high volumes or precision machined parts in low volumes, we’re here to deliver quality products on time. With years of experience under our belt, our professionals produce high-quality equipment from the simplest to the most complex. 

As we have mentioned the tips to ensure the quality of the CNC machined parts is ideal for both low-mid volume production. Here are the benefits of precision CNC machining to custom parts for low – mid volume production.
