摘要: 
In the operation of turning machining on the carbon steel, the cutting forces during
machining and the surface roughness of the machined parts are measured in this investigated. The
chips for every turning operation are collected and classified. Its formation in relation to the cutting
forces and surface roughness is analyzed. The primary physical parameters governing the turning
process are (1)cutting speed, (2)feed rate and (3) cutting depth. The experimental results show that a
broken or discontinuous chip is obtained under lower cutting speed and smaller cutting depth. The
continuous chips are obtained when the cutting speed increases. In order to lower the cutting force and
to obtain a better surface roughness, it is suggested that a higher cutting speed associated with proper
feed rate and cutting depth is used during the turning operation.

本文就碳鋼車削過程中,量測加工中之切削力以及加工後的工件表面粗糙度,同
時在收集與分類加工後的切屑之後,分析其與切削力及表面粗糙度之間的形成相關性,以
期得到理想的加工條件。車削過程的切削變化條件為(一)切削速度,(二)進給率,及
(三)進刀深度。由實驗觀察可發現在較低的切削速度與較小的進刀深度下,切屑呈破裂
不連續狀態。但在一般切削條件下,以較大的切削速度加工時,所得到的切屑呈連續狀態。
自實驗結果顯示,在較高的切削速度下,配合適當大小的進給率及進刀深度,可得到較低
的切削力與較佳的加工表面精度。
