Software to compensate geometrical and thermal errors
The trend for more and more accurate machines can be met by two different approaches. The classic approach attempts to improve the machine structure (guideways), to compensate for thermal displacements by thermally symmetrical design, and to avoid the build-up of heat by lubrication and by cooling. A new approach, made possible by advanced computer technology, is to implement theoretical models of the geometrical and thermal errors in machine tools into the control system. Software correction methods have been used to approach the problem of increasing the accuracy of a machine tool, with the objective of increasing the machine's accuracy by 70 %.
