Turning - machining calculator
Purpose : This excel will calculate for you : RPM, linear feed, Metal removal rate, chip dimensions. Specific cutting force, main cutting force, power required, cutting time, roughness.
Input : Turning External Diameter [mm], Cutting Speed [m/min], Depth of cut [mm], Feed per revolution [mm/rev], Length of cut [mm], Entry angle [degree], Rake angle [degree], Efficiency [%], Wear factor [%], tool nose radius, Based on material type and tensile strength.
output : Revolutions per minute [RPM], Linear Feed [mm/min], Metal removal rate [cm3/min], Chip cross section [mm], Chip width [mm], Chip thickness [mm], Specific Cutting force [N/mm2]or [MPa], Main cutting force [N], Power requirement [kW], Cutting time [min], Cutting time [seconds], Roughness profile depth [um]
