Online detection system and detection method for machining superhard cutters

Abstract

The invention relates to an online detection system and a detection method for machining superhard cutters. The system is characterized by comprising a numerical control system which is connected with two servo motors, an output end of one servo motor is connected with an electrical sparkle discharge electrode, and an output end of the other servo motor is connected with a measuring probe through a probe spindle. The measuring probe sends data to a receiver, and the receiver converts the data signals through a converter and then feeds the converted signals back to the numerical control system. The online detection system can detect whether machining parameters of a tooth are qualified or not when another opposite tooth of a superhard cutter is ground by an electrode, remachining procedures can be provided by the numerical control system, and all unqualified teeth can be repaired at once after machining of all teeth is completed. Therefore, once forming of the cutter is really achieved, cutter production efficiency is effectively improved, and mounting errors caused by repeated cutter mounting can be avoided.

Description

technical field [0001] The invention relates to a detection system and a detection method, in particular to an on-line detection system and a detection method for one-time forming processing superhard cutting tools. Background technique [0002] Precision CNC EDM machine tool is one of the important equipment of precision special processing technology. It is mainly used to process superhard materials and brittle materials that are difficult to process by traditional processing machine tools. It is used for precision machinery, automobiles, microelectronics products, and aerospace precision parts And precision mold processing is of great significance. EDM has the characteristics of no cutting force, no burrs and tool marks, and no need for the tool electrode material to be harder than the workpiece material. Therefore, machining superhard tools is another successful application field of multi-axis linkage CNC EDM technology one. However, there are the following three proble...

AI Technical Summary

Problems solved by technology

However, there are the following three problems in the process of EDM cutting tools: 1. The tool electrode is also worn out. 2. A metamorphic layer is produced on the surface after processing; it must be further removed in some applications; 3. When generating carbon slag and removing it Only under balanced conditions can it be carried out smoothly

This online detection system is a waste in the actual production process. Because another detection instrument is needed, the production cost is increased, and the tool is loaded multiple times, which increases the processing difficulty and introduces more processing errors.
