 note = {As heat sources of a compact CNC lath are closely-arranged, they would cause large and complicated thermal deformation. Thus, compact CNC lathes often arrange the heat sources and so on to reduce thermal deformation. The lathes taking such arrange into consideration can show high-precision work under stable environment. On the other hand, it would cause large thermal deformation at unstable environments. Previously, we proposed a simple method to compensate thermal deformation of CNC lathes by measuring temperatures at a few points such as spindle and tool. In order to apply similar method to a compact type lathe, we evaluated its thermal deformation. As a result, the thermal deformation of the evaluated machine is affected by the hydraulic unit as well as the spindle part. Thus, we tried to approximate the thermal deformation caused by the hydraulic unit and the spindle part respectively. Then, those thermal deformations can be expressed by simple equations. Furthermore, we applied these equations to compensate thermal deformation of the lathe. As a result, it is confirmed that the work error can be reduced under various conditions. © 2013 The Japan Society of Mechanical Engineers., 金沢大学高度モビリティ研究所 / 金沢大学理工研究域機械工学系},
