1.序言在研究机床的加工精度中,与机床结构的静刚度,动刚度并列的热刚度,即由于热而引起的结构变形也成为一个重要的因素。在机床内外具有各种热源,由于这些热源发热引起了机床结构的热变形,从而成为机床加工精度下降的一个原因。例在进行定位时,它要求严格的精度,但由于热变形的原因而使精度下降,而事实上也很可能得的定位是无用的。
1. Introduction In studying the machine tool’s machining accuracy, the thermal stiffness parallel to the static stiffness and dynamic stiffness of the machine tool structure, ie, the structural deformation due to heat, has also become an important factor. Inside and outside the machine with a variety of heat sources, as these heat source heat caused the thermal deformation of the machine structure, which became a reason for the decline in machining accuracy. In the case of positioning, for example, it requires strict accuracy, but the accuracy is reduced due to thermal deformation, and in fact the positioning that is most likely to be useless is useless.
