For this reason, it is suppressed that the cutting tool T receives the back component force F2 and inclines during cutting, and the inclined surface Wa can be processed with high accuracy.

Inclination can be suppressed, and the inclined surface Wa of the workpiece W can be processed with high accuracy. Further, since the inclination angle is measured by the measuring unit 140, the inclined surface Wa having a desired inclination angle can be reliably formed.
- the cutting when the measurement result of the inclined surface Wa by the measuring unit 140 is a desired angle, the cutting may be performed again without rotating the rotary table 137.
- the moving speed of the cutting tool T may be changed by setting the previous cutting process as a roughing process and the next cutting process as a finishing process. Whether or not the measurement unit 140 is installed is arbitrary, and the measurement unit 140 may not be provided.

Abstract
Description
第1実施形態に係る工作機械100について説明する。図1は、第1実施形態に係る工作機械100の一例を示す図である。工作機械100は、傾斜面Waを有するワークWを切削する旋盤であり、図1では旋盤の要部を示している。図1において、工作機械100の+Y側が正面であり、-Y側が背面である。また、工作機械100の±Z側は側面であり、Z方向は工作機械100の左右方向である。図1に示すように、工作機械100は、主軸10と、刃物台20と、移動装置30と、を備えている。これら主軸10、刃物台20、及び移動装置30は、例えば、工作機械100の外郭を形成する不図示のフレームに設けられている。
t=f2/8r
で表される。従って、送り量fを一定とした場合、切削部分の径が大きい位置では面精度tが高くなり、切削部分の径が小さい位置では面精度tが低くなる。そこで、例えば切削部分の径rに応じて送り量fを変化させることで、面精度tが一定となるようにしてもよい。例えば、傾斜面Waの小径部Wb側は、大径部Wc側に比べて径が小さい。このため、傾斜面Waの小径部Wb側を切削する場合には送り量fを小さくし、大径部Wc側を切削する場合には送り量fを大きくすることにより、傾斜面Waの径方向において面精度tを均一にすることができる。
