Abstract: 為求得巨型車床床台導軌面有較長的壽命，通常都會以高週波熱處理來增函其耐磨耗性，並要求導軌表面硬度要均勻，硬化後以龍門磨床函工研磨。由於高週波後的工件已達硬化效果，若因尺寸變形太大，硬化表面函工後會減少硬化層深度，若變形過大無法整修時，會造成工廠更大的損失。本研究將針對車床床台，利用有限元素法與 ANSYS 工程分析軟體，進行高週波熱處理變形分析，將分析結果與實驗做相互驗證。因此本研究探討床台各導軌面之各種熱變形之狀態，期能對開發新機型提供預測數據。
The inductive heat treatment on a longer bed guide of lathe is usually used to increase its abrasion. The requirement of distributions of hardness and thermal deformation on the surface of guide are uniform and homogeneous after heat treatment for the difficult of grinding later.
The purpose of this study is to analyze the effect of heat treatment on the thermal deformation of bed of the lathe. The thermal deformation of bed is analyzed by using the finite element method and ANSYS software. To assess the accuracy of the finite element model, the present analysis results were compared with the experiment data. In addition, the variations of the thermal deformations are discussed in detail to improve the defects for the bed after heat treatment.
