Abstract: A distance measurement holder is attached to the main shaft of a machine tool. A laser beam emitted from a holder main body is reflected by a reflection mirror section fixed to a tapered sleeve, and reflected by a measurement target, and then received by a light receiving section provided in the holder main body. The tapered sleeve is fit into the main shaft and supported to be rotatable relative to the holder main body. The distance measurement holder is shaped such that the angle of a side surface of the reflection mirror section changes in accordance with the rotation angle of the main shaft. The distance measurement holder thus configured determines the distance between the main shaft and the measurement target to determine whether or not a jig, a workpiece, the main shaft, and a cutting tool interfere with each other in the range of a rapid positioning motion specified in an NC program.

Abstract: A method calibrates a laser processing machine by commanding a scan head to direct a laser beam to a desired position, then senses an actual position of the laser beam directly using a position sensitive detector (PSD) after the scan head is positioned. A relative position between the scan head and PSD is altered using one or more linear actuators. A position feedback loop is closed around the linear actuators so that the relative position of the laser beam on the PSD is reduced to zero. The actual position of the laser spot is then measured indirectly by encoders attached to linear axes of the laser processing machine. The actual position is stored in a memory. An error is determined as a difference between the desired position and the actual position. Compensation coefficients are determined from the error and stored for later use during operation of the laser processing machine.
