ABSTRACT

Cutting force is very important data in machining , To make and the choice of correct tool, design the jig and machine. All shall be based on cutting force. In this study, single-door strain-gauged type and double-door strain-gauged type component force sensors are designed to collect the cutting data with these force sensors. This study aims at the strain-gauged type. the force sensor progress to studies, and to the force detecting flexible body progress designs and optimization and subjected to the finite element and shape optimization analysis using a computer-aided analysis software. Then the stress and strain distribution in the elastic members are obtained. The best location and direction for the strain gage is calculated and obtained. From which the magnitude of the three external force component may be determined by calculation. Come to acquire a good sensor of the performance, make the best detecting the sensibility.

Keywords : strain-gauge、wheatstone bridge、force sensor、cutting force、optimization、finite element Table of Contents
