[0030] like figure 1As shown, the numerical control device according to the first embodiment comprises a single-brick switch 2 on an operation panel 1 and an activation or activation member such as a start button 3 , similar to a conventional numerical control device. The digital control device also includes a machining program execution controller 4 , a machining program interpreter 5 , an interpolator 6 and a machining program memory 7 . When the digital control device is placed in the single block mode, when the start button 3 is pressed or other operations are performed, the machining program execution controller 4 makes the machining program interpreter 5 and the interpolator 6 work. Next, the interpreter 5 sequentially reads the machining program WP stored in the machining program memory 7 (see Image 6 ), the interpolator 6 generates the required position instructions. At the same time, the servo driver 9 controls the multi-axis servo motor 10 (ie, the driving mechan...

[0037] A second embodiment of the present invention will now be described with reference to FIGS. 4 and 5 . The digital control device of the second embodiment is substantially the same as the system in the first embodiment (see figure 1 )same. However, in this embodiment, in the single program block mode, if a program block contains a non-cutting instruction or an instruction for suddenly changing the processing direction is encountered or detected, the execution of the machining program at the block is suspended. , do not continue the tool movement until the start button 3 is pressed again. More particularly, as shown in the flowchart of FIG. 4 , in step S12, the machining program execution controller 4 judges whether the operation instructions analyzed by the machining program interpreter 5 include non-cutting instructions, for example: instructions for changing the rotational speed of the spindle The S command, the M command for changing the rotation direction of the sp...

Abstract

A numerical control apparatus with a single block function is provided including a start button ( 3 ), an execution amount setting unit ( 13 ), and a machining program execution controller ( 4 ). Once the amount of execution of the machining program to be executed by a single operation is set in the execution amount setting unit, the machining program execution controller ( 4 ) batch executes the blocks included in the set amount of execution upon a single operation, such as a depression, of the start button ( 3 ). Additionally, upon detecting a block including a non-cutting command or a command for abruptly changing a machining direction, the machining program execution controller ( 4 ) suspends the execution of the machining program as of that block and waits for the start button ( 3 ) to be depressed again.

Description

technical field [0001] The present invention relates to a numerical control device that sequentially executes a series of program blocks in a machining program by, for example, depressing an operation of an activation member thereof, so as to control the operation of a drive mechanism of a machine tool. Background technique [0002] Conventional numerical control devices, known to us, utilize the functions of a single program block for simultaneous inspection of the machining program and execution of the machined workpiece, which is executed sequentially or block by block by pressing its start member Run the processing program. E.g, Figure 7 The traditional digital control device shown includes a single block switch 52 and a start button 53 on the operation panel 51, wherein the single block mode is set when the single block switch 52 is turned on, and the single block mode is set when the single block switch 52 is turned on. Continuous processing mode is on when off. The...
