Good quality in parting and grooving is mainly dependent on the tool system and its behavior with the material being machined. However, tool maintenance is also important for the final machining result.
- Tool, insert geometry and grade affect the cutting quality. Wiper inserts improve the surface finish.
- Use correct feed rates for the insert and the material.
- Use a tool holder with a short overhang to avoid vibrations; use a sub-spindle if available.
- Chip breaking and chip evacuation must be satisfactory.
- Maintain the tools. Change the insert clamping screw regularly. Use a torque wrench.
- Establish a pre-determined tool life program.
