Problems solved by technology

[0003] The problem is that the automatic processing method in the prior art can only suspend the automatic processing process through the user's pause operation (machine keyboard) and planned stop (M01 command). Directly obtain other information except the coordinates of the pause point, and it is impossible to conveniently modify the processing parameters in the automatic processing program. The human-computer interaction is blunt and has great limitations on the processing technology.

Embodiment 1

[0043] Embodiment 1. Under the interactive method supported by the present invention, the craftsman can write an input dialog box when the part processing program starts, or after the CNC machine tool starts to execute the NC program and before the part processing program starts, requiring the operator to Input the number of repeated processing of parts and the interval time between repeated parts, and use the system variable to accept; the part program written after that can be cycled according to the number of times recorded in the system variable, that is, to realize batch processing of multiple identical parts.

Embodiment 2

[0044] Embodiment 2. Under the interactive method supported by the present invention, technicians can write an operator input dialog box when the part processing program starts, or after the CNC machine tool starts to execute the NC program and before the part processing program starts, requiring operation The operator enters his job number, accepts the job number string with the system variable, and then uses the file output command to include the operator’s job number and the processing start time into the file; before the end of the part program, combine the macro instruction to realize the End time and time difference calculation, write the file output command, and include the processing time into the file, which realizes the statistics of processing man-hours.

Embodiment 3

[0045] Embodiment 3. For the processing of parts with the same shape, different cutting parameters may be required due to different workpiece materials and tool materials. Under the interactive method supported by the present invention, the craftsman can write two input dialog boxes when the part processing program starts, or after the CNC machine tool starts to execute the NC program and before the part processing program starts, requiring the operator to input the workpiece respectively. Material and tool material, and use the system variable to accept the input result; after that, in the part processing program, according to the combination of the workpiece material and the tool material represented by the system variable recorded in the input dialog box, in the predetermined cutting amount recorded in the processing program by the craftsman Carry out optimization, enter the corresponding system parameters, and apply it to the subsequent part processing code to realize the s...

Abstract

The invention discloses an operating method for a numerical control system of a numerical control tool. A operating process is as follows: the numerical control machine tool starts to operate according to numerical control procedure codes; when the numerical control machine tool operates until an input / output command appears in the procedure codes, the numerical control machine tool stops operating, and a dialog box or a command statement is displayed at a display terminal to require a machine tool operator to input execution parameters; then after the parameters are input, the procedure codes have corresponding changes according to the input content; and finally the numerical machine tool executes the changed numerical procedure codes until the procedure is stopped. By adopting the operating method for the numerical control system of the numerical control machine tool, the machining process information can be prompted in time, the machining process can be revised in time through amending parameters by the operator, and selection can be performed on spot in numerous process schemes with established automatic machining procedures, thereby the process ability of automatic machining of the numerical control machine tool is expanded.

Description

technical field [0001] The invention relates to the operation mode of the numerical control system of a machine tool, and more specifically relates to the interaction method between the numerical control system and an operator. Background technique [0002] At present, the known automatic machining methods of the numerical control system use G codes to describe the motion trajectory, S codes to describe the rotational speed of the spindle, F codes to describe the feed speed, and M codes to describe the auxiliary functions that the logic system (PLC) needs to perform. The internal realization of automatic processing function of CNC system usually consists of several parts: CNC processing program file operator, program code parser (preprocessing unit), interpolator and other parts. [0003] The problem is that the automatic processing method in the prior art can only suspend the automatic processing process through the user's pause operation (machine keyboard) and planned stop...
