Accurate tool-setting method of numerical control machine tool and numerical control machine tool

Abstract

The invention discloses an accurate tool-setting method of a numerical control machine tool and the numerical control machine tool. The accurate tool-setting method of the numerical control machine tool comprises the steps that A, the machine tool drives a tool provided with an opposite charge tool edge to a workpiece to be machined, wherein the surface of the workpiece carries a charge; B, an electric spark detection module detects whether an electric spark is generated at the same time, wherein if an generated electric spark is detected, the electric spark detection module sends a high level signal to a processor, and the processor controls the numerical control machine tool to stop the movement of the workpiece to be machined and starts a machining program to machine the workpiece. According to the numerical control machine tool, whether the workpiece and the tool edge are aligned is judged according to whether an electric spark is generated between mutually exclusive charges carried by the workpiece to be machined and the tool edge, and then the workpiece machining method is implemented; since the numerical control machine tool can conduct tool setting automatically and accurately, more labor is liberated, and full automation is realized; the problem that fatigue of human eyes causes unqualified machining of the workpiece can also be effectively prevented, and the intelligent demand for numerical control is met.

Description

technical field [0001] The invention relates to the field of numerical control, in particular to a precise tool setting method of a numerical control machine tool and the numerical control machine tool. Background technique [0002] In industrial production, CNC machine tools are often used. When using CNC machine tools to process objects with high precision requirements, precise tool setting operations are required. This tool setting process is generally operated manually. At this time, the labor intensity is relatively high, so the human eyes are prone to fatigue, which will cause large human errors. The item does not meet the standard, resulting in loss. [0003] If the CNC machine tool can automatically and accurately set the tool, more labor will be liberated, and unnecessary resource and property losses can be avoided. [0004] Thereby prior art still needs to improve and improve. Contents of the invention [0005] In view of the deficiencies of the prior art abov...
