On the basis of analysis of and research on the current laser spectrum detection technology, the paper proposed the protocol that, use fiber optical antenna and modified wedge interferometer to obtain the laser interference fringe, t.

A kind of long rail measurement,based on wedge-shaped plate interference,has been developed,which is one of the important branch of geometry measurement.

An identification algorithm for tool interference in NC machining is presented based on the fuzzy inference techniques and pattern recognition theory.

The condition of tool interference about line tool-path and arc tool-path in automatic programming system of CNC lathe was analyzed,the processing method of tool interference was proposed.

Analysis of cutter interference on milling loxodrome grooves on rocket nozzle;

Presented in this paper is Characteristic Projection Method for avoiding cutter interference in 5-axis NC machining, which carried out interference checking through the detection processing of whether there are surface characteristic points located inside the cutter shape.
