Design and Implementation of CNC Milling Control System for Shift Hub Based on Constant Power Constraint
[Purposes]The core component of the automobile's dual-clutch transmission(DCT),the shift-ing hub,requires high precision in manufacturing.Aiming at the nonlinear problem of CNC milling pro-cess,the cutting parameters are optimized to improve the production efficiency and prolong the tool life.[Methods]This paper designs a milling control system based on a fuzzy control algorithm with the con-straint of constant power on the spindle load.This paper utilizes CP1E N30 as the main controller,devel-ops the sub-controller program using CX-programmer,and creates the upper-level system using Kingview to achieve the development of an intelligent controller based on spindle power signal feedback.[Findings]This paper implements constant power control for milling processes on the XHK716 machin-ing center machine tool.Through the application of shifting hub rough milling B plane process,it can be seen that the real-time power is maintained near the target power.[Conclusions]This control system has achieved the goal of improving milling process efficiency as well as protecting cutting tools,and provides valuable reference for extending tool life.
