Accordingly, various drive sources of the numerically controlled machine tool main body 10 are controlled. their control actions; In order to execute, the numerical control device 40 includes a control unit (CPU) 41 and a storage unit 2 is built-in, and further includes an external storage section 50, a keyboard 60, and a display device 7. 0 is attached.

0010 Here, the external storage section 50 can be removably loaded into the numerical control device 40. A storage medium such as a ROM is used and is packaged as a software package. This external storage unit 50 stores various data obtained through various processes performed in advance. data is stored as a data table. For example, when using ultrasonic processing, The following data is entered. Processing type Machining work Processing details Tools used Abrasive grain size Depth of cut feed rate Such, The external storage unit 50 also stores a control program, and a keyboard When instructions are given by the code 60, each data is controlled by this control program. data is searched and displayed on the display device 70.

[0011] Next, a method for setting ultrasonic machining conditions using an embodiment of the device of the present invention is illustrated. This will be explained based on FIGS. 2 to 10. After turning on the power, the software package menu 100 shown in FIG. Select the sonic processing management screen menu (menu 1). The contents of this menu are A screen 101 as shown in FIG. 3 is displayed on the display device 70. This screen displays the ultrasonic Displays the tool number and horn number attached to the spindle during machining. Also, adaptive control machine When the function is operating, the operating display will appear and at the same time the feed command value and overlap will be displayed. The ID value is displayed.

0012 After confirming this content, the machine operator can automatically set the machining conditions on screen 102 in Fig. 4. Select the confirmation screen menu.
