PEMBUATAN DAN PENGUJIAN TOOL HOLDER DYNAMOMETER UNTUK PENGUKURAN GAYA POTONG PADA MESIN BUBUT KONVENSIONAL

Abstract

Preparation  and  tool holder Dynamometer testing performed to produce a measuring tool cutting  forces on conventional lathes gauge. Sensor strain  sensor uses strain gauge used is 350 ohm types of prisoners, which is mounted on a ring segidelapan that have been modified for a more accurate reading, is the higher level the elasticity of the ring material will be more accurate readings, the working principle dynamometer for cutting force measurement is the mechanical stress on the rings due to cutting force, the mechanical stress that occurs is measured using a strain gauge sensors in the form of voltage  stress. In accordance with the testing parameters assume any lathe Feeding =

0.212 rev / sec n = 275 rpm Ingestion = 1.5 mm, cutting time of 120 seconds, the difference between the  voltage  before the funeral to  funeral time value obtained by

0.000029226 volt. hasil Vab obtained converted in the form of force (N). Keywords : Machine Tool, Tool Holder dynamometer, Measurement Style Cut.
