CUTTING RESISTANCE ANALYSIS DEVICE, CUTTING AND MACHINING DEVICE EQUIPPED WITH SAME, AND CUTTING RESISTANCE ANALYSIS PROGRAM

摘要

A cutting resistance analysis device is adapted to calculate cutting resistance at a plurality of machining points along a path of movement of a multi-blade rotary cutting tool in cutting and machining of a workpiece using the multi-blade rotary cutting tool. The cutting resistance analysis device includes a data storage section, a cutting resistance calculating section, a contact blade count calculating section and a per-blade cutting resistance calculating section. The contact blade count calculating section is configured to calculate a number of blades of the multi-blade rotary cutting tool that are simultaneously in contact with a machining face of the workpiece. The per-blade cutting resistance calculating section is configured to calculate the cutting resistance per blade of the multi-blade rotary cutting tool based on the amount of cutting resistance and a calculation result of the contact blade count calculating section.
