Instructions

1. This calculator is designed for quick calculation of turning process parameters, including key parameters such as machining time, cutting speed, and spindle speed.

2. Please select the appropriate calculation type based on your actual machining requirements and enter the correct parameter values.

3. For cutting force calculation, the specific cutting force (Kc) must be selected according to the workpiece material.

4. The mechanical efficiency (η) typically ranges from 70% to 85%, and can be adjusted based on the machine tool condition.

Disclaimer： All calculation results are for process planning reference only. Actual machining should be adjusted according to on-site conditions such as machine tool performance and tool condition. Trial cutting is recommended before full production. This tool assumes no liability for the results of use.
