Paper Title:
Research on PID Control Model for Error Compensation in Milling Thin-Wall Parts
  Abstract

Accuracy of machined components is one of the most critical considerations for any manufacturer. To improve the accuracy by diminishing errors in CNC milling thin-wall parts, this article analyzes sources of errors and provides PID control model to error compensation, namely acquiring offset value by calculating the coefficients of proportional, integral and differential and corresponding errors, and then adjusts codes of next processes. The effectiveness of PID control model in improving accuracy is testified by experiments contrasting with groups of non-compensation and completely-compensation. The experiments have proved that PID control model of CNC milling thin-wall parts can predict machining error trends and have advance regulation.
