Accurate control system for automatic calibration of workpiece of numerically-controlled (NC) cutting machine

Abstract

The invention provides an accurate control system for the automatic calibration of a workpiece of a numerically-controlled (NC) cutting machine. A cutting machine automatic feeding system comprises aworkbench, a milling cutter, a detection module and a control console. The detection module is connected with the control console, and can be installed at any fixed position of the workbench. The detection module is composed of a three-dimensional laser scanner and a point laser distance measuring sensor connected in series. The control console is composed of a display screen and a calibration button. Aiming at the problems that during the repeated machining process of soft materials, the deformation is large and the accuracy is low, and the situations that the manual calibration mode is relatively large in error and relatively low in efficiency, the invention designs an automatic workpiece coordinate system calibration system, for performing error compensation and automatic calibration onthe workpiece coordinate system, and thus the accurate machining of the soft materials is achieved, the better benefit is brought to the enterprise, and the market application value is achieved.

Description

technical field [0001] The invention relates to the technical field of cutting machines, in particular to an automatic calibration system for CNC cutting machine workpieces. Background technique [0002] In the process of soft material processing of CNC cutting machine, due to the large deformation of soft material, in order to improve the cutting accuracy, it is necessary to periodically calibrate the position of key workpieces of the cutting machine, such as milling cutters. There are large errors and low efficiency through manual calibration. Therefore, it is necessary to design an automatic calibration system to calibrate the workpiece coordinate system of the cutting machine, so as to improve the processing quality of the enterprise. The invention solves the problem of large deformation and poor precision of the cutting machine during the repeated processing of soft materials by designing an automatic workpiece calibration system to perform error compensation and automa...
