INDUSTRIAL MACHINE AND METHOD FOR MEASURING AMOUNT OF EXPANSION/CONTRACTION OF INDUSTRIAL MACHINE |
| 摘要 |
An industrial machine includes a moving mechanism moving one of a probe and a tool relative to a work piece, using three displacement axes parallel to each of three orthogonal axis directions; a low thermal expansion member formed with a material having a smaller thermal expansion coefficient than a material forming a structural element of the moving mechanism; and an expansion/contraction measurer measuring, using the low thermal expansion member as a reference, an amount of expansion/contraction of the structural element in one of the three orthogonal axis directions, the expansion/contraction occurring due to a change in temperature. |

1. An industrial machine comprising:
a moving mechanism configured to move one of a probe and a tool relative to a work piece, by using three moving axes parallel to each of three orthogonal axis directions; a low thermal expansion member comprising a material having a smaller thermal expansion coefficient than a material Banning a structural element of the moving mechanism; and an expansion/contraction measurer configured to measure, using the low thermal expansion member as a reference, an amount of expansion/contraction of the structural element in one of the three orthogonal axis directions, the expansion/contraction occurring due to a change in temperature. |
