Abstract: As shown in FIG. 1, a position detector (10) includes: an object to be detected having a pattern (2) formed for generating a position signal; and a sensor (3) for detecting the position signal according to the pattern (2) by receiving an electromagnetic wave generated on the object (1) by light irradiation. The pattern (2) is formed in a gradation shape visibly or invisibly so that an electromagnetic wave having a wavelength continuously different depending on the position on the object (1) can be sent to the sensor (3). This enables detection of an absolute angle of a rotary object and an absolute position on an XY plane with a simpler configuration, simplifies the device assembly, and reduces the device size.

Abstract: A machine tool having a turning function and a milling function includes a spindle, a spindle housing supporting the spindle in a rotatable manner, a main clamp provided at the spindle, an auxiliary clamp provided at the spindle housing, and a double arm with a first gripper and a second gripper. The auxiliary clamp clamps a tool holder together with the main clamp during fixing a fixed tool.

The auxiliary clamp is arranged at a position not interfering with the double arm that moves during exchanging tool holders. By such a configuration, a machine tool achieving a clamping force sufficient to withstand the load during a turning process, and that allows tool exchange in a short period of time, and a tool holder employed in such a machine tool, can be provided.

Abstract: A reference mirror 21 is disposed on a table 2, a first laser displacement sensor L1 for measuring a machined surface of a workpiece W and a second laser displacement sensor L2 for measuring a reference surface of the reference mirror 21 are disposed to a tool holder 3. A measurement motion applying section 24 causes the table 2 and the tool holder 3 to relatively move in a sinusoidal trajectory, and a sensitivity calculating section 28 calculates sensitivity of the first laser displacement sensor L1 based on machined-surface displacement data and reference-surface displacement data which are measured during the relative movement. Subsequently, an actual shape data calculating section 29 corrects the machined-surface displacement data based on the calculated sensitivity, and calculates actual shape data of the machined surface by taking the difference between the corrected machined-surface displacement data and the reference-surface displacement data.

Abstract: A numerically controlling apparatus is provided in which the automatic operation of a machine tool can be stopped at a desired block and yet at plurality of desired blocks without changing NC programs. In this numerically controlling apparatus, an operator performs a change into the “EDIT” mode with a mode selecting switch on a keyboard 18 and makes the cursor shifted up to the block, at which the automatic operation is desired to be stopped, with the keyboard 18, in the state where the NC program for setting stop points is displayed in the image 20. By pushing the “SET STOP POINT” key 24A provided in the key display area 24, the stop point 25 indicated with a “red circle” is set ahead of the block. When, in the course of the automatic operation of the machine tool, the action due to the command of the block, for which the stop points 25 is set, has been completed, the automatic operation of the machine tool becomes stopped.
