Abstract

The invention also relates to a method for realizing automatic scanning height measurement in a numerical control system, comprising the following steps: (1) the numerical control system pre-generates scanning tracks; (2) the numerical control system performs scanning height measurement. The method of automatic scanning height measurement in the numerical control system of the present invention is adopted, and the automatic scanning height measurement can effectively solve the problems of traditional contact height measurement, such as low efficiency, large error, and easy damage to workpieces. Using automatic scanning altimetry can collect a lot of altimetry point information. Better obtain the surface information of the workpiece, and then more accurately adjust the Z-axis height during processing, to ensure a constant distance from the cutter head to the workpiece surface, and to ensure better cutting quality.

Description

technical field [0001] The invention relates to the field of automatic control, in particular to the field of automatic height measurement of machine tools, in particular to a method for realizing automatic scanning height measurement in a numerical control system. Background technique [0002] The height measurement function is used to measure the height difference of the workpiece surface, so that during automatic processing, the height difference between the cutter head and the workpiece surface is constant, ensuring that automatic processing can achieve better processing results. The traditional height measurement function generally adopts the method of contact height measurement, that is, during the height measurement process, the Z-axis descends at the position of the height measurement point until the height measurement signal (IO signal) is obtained, and finally a single height measurement is determined. point height value. [0003] For processing workpieces like "r...
