Title: Device for monitoring machining load of machine tool
Inventor: TORISAWA YOSHIO
IPC: B23Q17/09
Filed: 1988-02-25
Abstract: PURPOSE:To improve the monitoring accuracy of machining load and obtain a high-quality machined object by detecting the error in strength of an AE signal which damps down depending on the propagated distance and direction in a plurality of places and processing the error to be small. CONSTITUTION:A vibration or a sound signal generated at the time of machin ing is detected by AE sensors Sa-Sc and the detected signals SAa-SAC are inputted into a machining load monitoring device 100. Each signal is amplified by each amplifying portion 11a-11c and a signal which is hard to be affected by a machining position among the amplified detected signals ASAa-ASAc, e.g., the largest one is synthesized by a load signal synthesizing portion 101 to be a synthetic signal and outputted to a load monitoring operating portion 13 via a filtering portion 12. Thereby, a load monitoring threshold value can be easily set reducing manhour while improving machining load monitoring accuracy to obtain a high-quality machined object.
