Description

technical field [0001] The invention relates to the technical field of measurement methods of machine tool parameters, in particular to a method for online measurement of inclined shaft holes of a five-axis machine tool. Background technique [0002] The online measurement system of CNC machine tool is mainly divided into hardware part and software part. The hardware part takes the machine tool as the main body and connects the measuring head system, and the software system is mainly composed of computer system. The five-axis CNC machine tool structure generally consists of three moving axes and two rotating axes. As early as in foreign countries, this measurement method integrating computer control, high-performance servo system, precision machining and detection technology has been put into use. [0003] Conventional NC processing machine tools are the first choice of most enterprises. When processing conventional parts, it is necessary to understand the drawings and perf...

Problems solved by technology

[0003] Conventional NC processing machine tools are the first choice of most enterprises. When processing conventional parts, it is necessary to understand the drawings and perform manual measurement. Some need to make process points, lines, holes or other auxiliary benchmarks to determine the processing position. It takes a long time to wait for the detection to complete

The measurement of inclined hole parts is more cumbersome and time-consuming. Manual measurement and re-clamping after off-line measurement will greatly affect the previous measurement results, resulting in processing errors.
