Common Tool Cutting Problems in CNC MachiningWhile 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
Hitting CuttersThis 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.
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
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.
