Machine tool control apparatus

摘要

The invention aims to reduce an error occurring due to the mounting condition of an acceleration sensor. In the case of a two-axis sensor, an angle ¸ is calculated from outputs (x', y') that the acceleration sensor produces when known accelerations (x, y) are applied, and the angle ¸ is stored in a storage device contained in a casing in which the acceleration sensor is housed. In the case of a one-axis sensor, the ratio of the magnitudes of accelerations is stored. The acceleration detected by the acceleration sensor is compensated by using the value stored in the storage device.
