1. Reasonably control cutting force and cutting speed
Reasonably controlling the cutting force and cutting speed of various irregular cutting tools is also one of the means to reduce the temperature in the machining area and extend the service life of cutting fluid. When processing difficult to machine materials, precision ground materials are generally used. The cutting depth and width should not be too large.
2. Choose a reasonable cutting method
For difficult to machine materials, choosing different cutting methods has a significant impact on tool damage. No matter which cutting method is chosen, the principle is the same, which is to minimize the cutting force of various irregular cutting tools and the temperature of the cutting zone. The cycloidal cutting method can greatly reduce the cutting area, thereby extending the heat dissipation time of each tooth and reducing the cutting temperature.
3. Ensure timely chip breakage
Chip breaking is a good method for controlling cutting temperature. When processing difficult to machine materials, chips should be generated as much as possible throughout the entire processing process while ensuring the rigidity of the processing system. At the same time, use cutting fluid with good sedimentation performance to discharge chip deposits, and do not let the chips rub against the surface of the workpiece.
