Knife hitting plate wear automatic compensating method of contact type knife damage detection system

Abstract

The invention discloses a knife hitting plate wear automatic compensating method of a contact type knife damage detection system and belongs to the technical field of machining. The contact type knife damage detection system comprises a knife hitting plate in contact with a knife, a driving component used for controlling the movement of the knife hitting plate and a control system. The control system calculates the wear value of the knife hitting plate which collides with the knife and carries out automatic compensation on the length of the measured knife. Through the knife hitting plate wear automatic compensating method, measurement errors caused by the wear of the knife hitting plate can be offset, the use time of the knife hitting plate is increased, and the maintenance cost of changing the knife hitting plate and correcting the wear quantity of the knife hitting plate is reduced.

Description

technical field [0001] The invention relates to a method for automatically compensating the wear of a cutting plate of a contact type tool damage detection system, belonging to the technical field of mechanical processing. Background technique [0002] Existing CNC machining centers widely use a contact tool breakage detection system for tool breakage detection. The detection plate of the detection system moves from the front of the tool to the tip of the tool until it hits the tip of the tool and stops. The system will determine the length of the tool to be measured according to the position of the cutting plate when it stops, and then compare it with the length of the tool recorded by the system to determine whether the tool is broken or damaged. In actual use, in order to prevent the tool from being damaged, it is not allowed to use too hard metal material as the knife plate. Therefore, the long-term contact between the knife plate and the tip of the knife will inevitably...

AI Technical Summary

Problems solved by technology

In actual use, in order to prevent the tool from being damaged, it is not allowed to use too hard metal material as the knife plate. Therefore, the long-term contact between the knife plate and the tip of the knife will inevitably cause wear and tear, which will affect the measurement accuracy of the tool damage detection system, and cause machine tool damage. false alarm

This requires the user to regularly replace the knife plate or manually correct the wear of the knife plate, which increases the use and maintenance costs of the machine tool
