Determination of diametral error using finite elements and experimental method

Abstract

This study concerns experimental and numerical analysis on a one-sided bound workpiece on the lathe machine. Cutting force creates deflection on workpiece while turning process is on. Deflection quantity is estimated utilizing Laser Distance Sensor (LDS) with no contact achieved. Also diametral values are detected from different sides of workpiece after each turning operation. It is observed that diametral error differs due to the quantity of the deflection. Diametral error reached a peak where deflection reached a peak. Model which constituted finite elements is verified by experimental results. And also, facts which caused diametral error are determined.
