TWO-COMPONENT DYNAMOMEETR FOR MEASUREMENT OF CONSTITUENTS OF CUTTING FORCE

摘要

FIELD: machine building. ^ SUBSTANCE: two-component dynamometre for measurement of constituents of cutting force is made of two mutually perpendicular upper and lower loading devices each corresponding to loading desk consisting of loaded cover and prismatic element connected with screws. The loading desk is mounted on a sliding seat in a base; it is fixed with holders in form of prismatic guides, steel balls and tightening bolts preventing cross shift of the desk. Two tensometric sensors are arranged in lengthwise direction on each side of prismatic guides of the both upper and lower loading devices. Under influence of cutting force the loading devices travelling lengthwise through steel balls and along prismatic guides effect the tensometric sensors. A processed item can be arranged on surface of the desk cover of the upper loading device. A base of the upper loading device is the cover of the lower loading device. ^ EFFECT: upgraded accuracy, convenience in maintenance and visualisation of tests. ^ 2 dwg
