Improving CNC Machining Lifespan and Cutting Efficiency

Every manufacturer has come to a point where they are asking themselves how to increase tool life and cutting efficiency. Ideally, CNC machining should focus on efficiency and productivity improvements. There are various steps one can take to improve the productivity and efficiency of their CNC machine. Read along to know 5 ways of processing optimization.

1. Tool life, surface roughness, time cycle, and part quality

When you start designing a machining plan or trying to modify the existing program, it is essential to consider tool life, surface roughness, time cycle, and part quality as the main objectives. After this, you can narrow it down to something specific and quantified indicators that are going to be accepted. Additionally, when creating the processing plan and setting a target, it is wise to consult a cutter seller who would advise you on the best way to attain returns and success.

2. Understanding generation and work principle of the cutter

It’s essential to have a bit of knowledge when it comes to cutting force law, as it will put you in the best position to know the direction of the cutting force. This will go a long way in improving the clamping stiffness of CNC machining parts. You can also be able to improve processing optimization by changing the radial force. You change the radial force to the direction of the axis force keeping in mind the method with which you can reduce cutting depth.

3. Identifying and Addressing Issues

When you notice your CNC machining process is faulty, it’s prudent to analyze carefully to determine whether there is a problem in the processing areas or are problems due to improper cutting tools. It’s always best to find the problem’s root cause before jumping to conclusions. For instance, while the machine is operating, you can cross-check the cutting tool to see if the problem emanates from the fixtures or the cutter.

While at it, you can go ahead and check whether or not the tool is damaged. You do so by checking the machine stiffness, cutting parameters, chip removal, and coolant. If there are any damaged parts here, you can easily replace them with new ones.

4. Selecting the Best CNC Machining Plan

In some circumstances, you need to choose a specialized machining plan so that you are able to improve on production efficiency. For instance, when you desire to mill large holes in a singular and yet short production cycle, going for integral spiral milling cutters will make productivity efficient when compared to drilling big holes.

Another unusual yet economical way of increasing productivity will be plunge milling. This process has proven to increase efficiency and productivity 4 times over the normal milling ends.

5. Having Extensive Knowledge about Cutting Temperature

You need to know the generation area, advantages, and disadvantages. When cutting metals, temperatures rise due to friction, which can be disadvantageous when it comes to CNC machining. This is more so when cutting steel parts.

The high temperatures can even soften parts to form ideal chips. It is essential to try and avoid consequences that come with too high cutting temperatures like tool overheating, parts hardening, and decarburization.
