TOOL GRASPING FORCE MEASURING SYSTEM AND TOOL GRASPING FORCE MEASURING METHOD

摘要

A tool holding force measuring system 1 comprises a main shaft held part 21 having substantially the same shape as a held part 402 of a tool 400, a slide member 28 displaced by taking the main shaft held part 21 in a clamping mechanism 304, a load cell 23 detecting the displacement amount of the slide member 28 so as to calculate the holding force of the clamping mechanism 304 based on the displacement amount, and a radio transmitter 24 outputting the holding force of the clamping mechanism 304 calculated by the load cell 23 by transmitting it on radio. Accordingly, one operator can measure the holding force.
