測方法にて行なう。FIG. 6 is a block diagram of a conventional numerical control device with a measurement function. In the figure, a main control section 1 that controls the entire numerical control device sends measurement commands to an axis control 8 processing section 4°. The axis control processing unit 4° that has received the measurement command sends a control axis movement command in the measurement direction to the servo motor control processing unit 5. The servo motor control processing unit 5 that receives this control axis movement command performs drive control of a control axis servo motor (not shown), while the touch probe 7 touches the object to be measured while the control axis is moving during measurement. When touched, the touch signal output from the touch probe 7 is inputted to the touch probe control device 6 and further sent to the axis control processing section 4''.The axis control processing section 4'' that inputs this touch signal immediately The main controller 1' stores the control axis position as the latch position and sends that information to the main i!lJN unit 1' to roughly stop the control axis movement. Once the position is recognized, the measurement in one direction is completed.The same measurement method is used for the remaining directions.

いう問題点があった。(The problem that the invention is trying to solve!!!) However, as mentioned above, in the conventional system, the index angle in the rotational direction of the spindle to which the touch probe is attached is always constant, so the diameter correction of the touch probe itself is -It was necessary to measure in the four directions of the Y coordinate.However, although a reference workpiece is generally used for this measurement, this work requires great skill, and the touch probe measurement ring does not touch the reference workpiece. Since the portion (contact portion) changes depending on each measurement direction, there is a problem in that a measurement error occurs and highly accurate measurement cannot be performed.

軸制御手段を備えることによって達成される。(Means for Solving the Problems) The present invention relates to a numerical control device equipped with a measurement function that measures a workpiece by indexing the spindle. In a numerical control device equipped with a measurement function capable of measuring the dimensions of an object to be measured by attaching a probe and bringing the touch probe into contact with the object, the touch probe is attached to the object to be measured. When making contact, the index angle in the rotational direction of the main shaft is determined in advance so that the contact part of the touch probe is always at the same point according to the moving direction of the control shaft of the touch probe. This is achieved by providing a spindle control means for positioning.

当接位置と２識して一方向の計測を終了する。Next, the measurement operation in the present invention will be explained based on Figure 1 and Figure 2. First, the main control unit 1, which controls the entire measurement function, determines the rotational direction of the spindle based on the direction of movement of the control axis when bringing the touch probe into contact with the object to be measured. ) An angle command is output to the spindle indexing control section m2. The spindle indexing control unit 2 that received the command issues a spindle indexing command to the spindle drive unit 3, and the spindle drive unit 3 that received the indexing command performs an indexing operation of the spindle motor. After the index angle positioning operation is completed, the spindle control unit 1 sends a measurement command to the axis control processing unit 4, and the axis control processing unit 4, which has received the measurement command, issues a control axis movement command in the direction of measurement. It is output to the servo motor control processing section 5. The servo motor control processing unit S that receives this command performs drive control of the control axis servo motor.
Therefore, when the touch probe 7 comes into contact with the object to be measured during movement of the control axis during measurement, the touch signal output from the touch probe 7 is input to the touch probe control device 6, and further sent to the axis peeling process 1i1S4. It will be done. The axis control processing unit 4 that receives this touch signal immediately stores the current control axis position as a latch position, sends the information to the main control unit 1, and further stops the control axis movement. The main control unit 1 recognizes the latch position as the contact position of the touch probe and ends the one-way measurement.
