A growing number of companies in the manufacturing sector are utilizing CNC cutting machines to help accommodate their various material cutting requirements. We qualify CNC machine cutting tools as a subtractive type of manufacturing technology. It is because this method of cutting and shaping an object involves the removal of the material from a solid object.

Several cutting tools are involved in CNC machining process. They are made to rotate at ultra-high speeds so they can create and shape the part you require to make, and everything that this process does will be based upon your particular design drawing. Needless to say, they have a significant role to play in the CNC machining process since they make direct contact with your workpiece and they are the ones that chisel your material to make your desired features.

The vast majority of CNC cutting tools come with a cylindrical shank. The cutting tip comes with a certain shape and it’s cutting length is limited. Those two cutting tool features work to its disadvantage because it is putting a limit on what they can cut. On the account of tool geometry, it poses a great challenge if you will try and make vertical rectangular corners. And with respect to the cutting length, features like undercuts and small deep holes can’t be handled by the CNC machining process.

CNC Design Tips

We have compiled below several valuable tips you can use as guidelines for CNC machining. They are very useful tips you need to take good advantage of and are described as follows:

1. Limit Cavity Depth

Tools used in machining are likely to work at their best if your cut cavities have a depth of about 2-3 times their diameter. Milling cavities that come with a diameter that is 4x compared to that of the tool are likely more susceptible to tool breakage and prone to suffer greater challenges. This will brings about extra machining costs.

Whenever possible, the pocket should come with a depth that is 4 times less than the diameter of the tool.

 2. Make Thin Walls Thick

When it comes to CNC machining a thin wall, it is likely to present you with a far greater challenge than you can expect. They are prone to fracture and can easily get deformed. It necessitates your premier CNC cutting machine to have multiple passes at it in low cutting depth.

Thin walls are also prone to vibrations, increasing the level of difficulty when machining them as well as the time it will take to get the job done right the first time.

3. Reduce Small Features

When we speak of small features, we are pertaining to micro-holes. These are hole openings that are about 2.5mm in diameter. Such features will render your machining work to have an increased level of difficulty. It will also make your actual machining time far longer than earlier anticipated. You need to veer away from this unless necessary.

Bonus Tip

When trying to come up with a design intended for CNC machining, it is an absolute must that you see to it that your designed parts will allow you to machine it in as little as a few steps as possible. It would be much better if it can be done with just one, single setup.

The less setup you have, the better because it will lessen the amount of time needed to re-align the workpiece to increase the machined parts level of accuracy.
