3 Common Types of Cutting Issues in CNC Machining That Result in Tool and Material Damage

The use of computer numerical control (CNC) machining has become increasingly popular in the manufacturing industry due to its accuracy and efficiency. Despite its advanced technology, CNC machining can still face cutting issues that result in material damage and tool deformation. Understanding these issues is crucial in order to minimize downtime and avoid damage to workpieces and tools. In this post, we will discuss the three common types of cutting problems that result in material damage and tool deformation in CNC machining.

Hitting Cutters

The first issue is hitting cutters, which occurs when the cutting tool cuts a large amount of material from the workpiece and collides with it during the process. This collision results in high vibration and damage to the workpiece. Several factors can contribute to hitting cutters, including a large tool diameter, improper machining method, and incorrect safety height. In order to avoid hitting cutters, it is important to choose a smaller cutting diameter tool, select an appropriate machining method based on the tool type and work requirement, and select a higher safety height to avoid hitting the clamping.

Bouncing Cutters

The second issue is bouncing cutters, which can result in tool deformation and material damage due to excessive vibration caused by excessive force on the tools. The factors that contribute to bouncing cutters include tool diameter, tool length, and force on the tool during cutting. Choosing a larger diameter tool and shorter tool can help minimize deformation. Reducing the force on the tool during cutting can also help to minimize deformation.

Overcutting

The third issue is overcutting, which is when more material is cut than required and results in damage to the workpiece. In order to avoid overcutting, it is important to closely monitor the tool path and be careful while cutting.

In conclusion, understanding the common types of cutting problems in CNC machining can help manufacturers minimize downtime and avoid damage to workpieces and tools. By choosing appropriate tools, selecting the right machining method, and closely monitoring the tool path, manufacturers such as Epic Tool can ensure a smooth and efficient CNC machining process. Partnering with reliable CNC machining services that adhere to industry standards can also help to ensure a successful outcome.
