Description

technical field [0001] This application relates to a measurement method for mechanical movement positions, and is especially suitable for some numerical control equipment that requires frequent reciprocating movement position detection. Background technique [0002] In the CNC numerical control system, the coordinate position detection is an important part of the automatic closed-loop feeding system. Whether the machine tool coordinates can reach the specified stroke position directly determines whether the workpiece accuracy can meet the process requirements. [0003] For machine tools with reciprocating coordinates, the position detection of the coordinate stroke needs to be stable and efficient. There is a five-coordinate CNC forming plane guide rail grinding machine, the X-direction movement mode is reciprocating, and the original position detection adopts the magnetic scale measuring device. This kind of detection device is easy to be polluted and damaged. The grinding ...
