AI Technical Summary

Technical Problem

During the CNC milling process of the control block of a commercial vehicle transmission, the high temperature and pressure of the aluminum alloy material cause cold welding and adhesive wear on the rake face of the tool, forming built-up edge, damaging the machined surface, and causing the workpiece to be scrapped.

Method used

The thermoelectric monitoring component is used to acquire the thermoelectric potential signal of the contact area between the tool and the workpiece in real time. The controller determines the adhesion state and switches to the cooling medium spray mode to use the extreme low temperature medium for instantaneous cooling to prevent the formation of built-up edge.

Benefits of technology

It effectively prevents the adhering material from further evolving into built-up edge, ensuring the integrity of the machined surface of the transmission control block.
