How Do Cast Iron Inserts Help with Sound Control

Cutting insert rake angle plays a crucial role in turning performance and determines the efficiency of the machine tool. It influences a range of machining parameters such as tool wear, cutting force, surface roughness, chip control, and heat generation. These factors eventually impact the productivity, quality, and cost of the machining process.

Rake angle determines the angle between the cutting edge and the workpiece material during cutting. It can be positive, negative, or zero depending on the orientation of the rake face. The positive rake angle refers to a leaning of the cutting edge towards the workpiece material. This angle is preferred when machining soft materials as it reduces cutting forces and prevents tool wear. On the other hand, negative rake angle is suitable for cutting hard materials as it increases the strength of the cutting edge and provides better chip control.

The cutting insert rake angle also affects the surface finish quality. A larger rake angle results in better surface roughness as it reduces the tendency of the tool to chatter and increases the stability of the cutting process. However, excessively large rake angles can cause problems such as increased cutting forces, vibration, and heat generation. To maintain a balance between cutting edge strength, surface finish, and chip control, a moderate rake angle is preferred.

In addition, rake angle also influences the cutting temperature and, thus, the tool life. A higher rake angle reduces cutting temperature, which leads to longer tool life and better cutting performance. However, it can TNGG Insert also result in increased distortion of the machined part due to thermal expansion. Therefore, the selection of the correct rake angle is CCMT Insert critical to maintaining a balance between cutting temperature and dimensional accuracy.

In conclusion, the cutting insert rake angle plays a significant role in turning performance, affecting the tool life, cutting forces, surface roughness, chip control, and thermal expansion. Selecting the appropriate rake angle for a specific material and application can improve machining performance, reduce costs, and increase productivity. Machining experts should consider the various factors involved in determining the rake angle and choose an angle that provides the best results.
