摘要: 
熱的問題一直是影響工具機精度的主因,由於工具機機台精度的穩定性要求日益嚴苛,發展有效且可靠的熱誤差因應技術,已是近年來工具機技術發展必要投入的重點項目之一。本研究針對主軸熱誤差建立一套線上即時補償系統。

首先利用空切削和實際切削進行量測,並記錄相關溫度點變化和碰觸式探頭熱變位移量,以蒐集溫度變化量與熱變位量之數據,再利用多變數迴歸的方式分析其相關性,以最具相關性之溫度點建立補償預估模型。

在本論文中使用8051單晶片數位電路,根據補償預估模型以組合語言撰寫軟體程式,希望發展一套低功耗、高計算效能、低成本,的補償模組,主要負責補償模型運算以及與CNC控制器溝通,利用PMC卡之外部機械原點漂移的方式,將補償值輸入控制器,以達到減少熱誤差的目的。

The thermal problem has always been a main reason influencing the tool machine precision. As the stability of the tool machine precision is being required severely day by day, in recent years, developing the effective and reliable thermal error technology is necessary of the tool machine. This research builds a thermal error compensation system of spindle thermal error.

First, measuring the experiment data by un-virtual cutting and virtual cutting for collecting temperature position order and trigger probe (TS27R) position shift data. Next, multiplying regression method to establish a thermal predict model.

8051 single chip logic circuits was used to write the software procedure in assembly language which based on compensating and estimating models, expecting to develop a less-consumptive, higher-efficient and lower-cost compensation model in this research that mainly deal with compensating the operation of model and communicating with CNC controller. In order to achieve the goal of reducing the thermal error, the way in which shifted the zero point of the machine coordinate system from the external PMC card, the compensation will be input to the controller.
