How to Prevent Tool Deformation and Material Damage in CNC Machining

One of the biggest issues when using CNC or computer-controlled cutting machines occurs when tools or material are damaged during use. It is always important to inspect the machinery and tools properly to ensure they operate as expected. It helps to minimize damage during operation. When machinery or tools are damaged, customers can rely on Allied Marine & Industrial machinery repair services to fix problems that arise.

Common Tool Cutting Problems in CNC Machining

While computers help to operate the machinery, there can still be problems with the operation of the device. Listed below are the three most common problems facing CNC machine operators:

• Hitting Cutters
• Bouncing Cutters
• Overcutting

Hitting Cutters

This occurs during the process when the workpiece and cutting tool product vibrations which can damage the workpiece and the tool. Reasons to avoid hitting cutters are listed below:

• High Cutting Amount
• Inappropriate Machining Method
• Improper Safety Heights

High Cutting Amount

When a tool has a large diameter is one of the biggest reasons for high cutting amount. This is easy enough to address and can be reduced by choosing a tool with a smaller cutting diameter. Cutting amounts can correspond to various methods. As an example, finishing and semi-finishing need a much smaller tool diameter than other methods of cutting.

Inappropriate Machining Method

It is paramount to select the proper machining method to both the type of tool type. While a small tool diameter is perfectly suited to perform contour milling, it is better to select a cavity milling if the tool diameter is overly large.

Improper Safety Heights

It is imperative to select appropriate safety height to avoid hitting the clamping during tool lifting. It is better to maintain a proper safety height.

Bouncing Cutters

This can easily cause tool deformation and material damage in CNC cutting machines. Typically, this occurs because of significant vibrations caused by excessive force applied to the tools used. The primary factors that influence bouncing cutters are listed below:

• Tool Diameter
• Tool Length
• The Amount of Force Applied

Overcutting

This occurs when the piece is cut more than required. This can also damage the workpiece. One of the ways to combat the occurrence is to keep an eye on the tool path of the CNC turning machining services equipment. This also means that it is essential to carefully operate the machine while cutting with the tool.
