DESCRIPTION:
BRIEF SUMMARY
FIELD OF THE INVENTION
This invention relates to a method of creating NC data for hole machining and, more particularly, to a method of specifying the type of hole to be machined and creating hole machining NC data in dialog fashion.
DESCRIPTION OF THE RELATED ART
A dialog-type numerical control apparatus is available in which a dialog screen and a function key screen are displayed on a display unit in accordance with each step of a plurality of data input steps, a predetermined function key (soft key) on the function key screen is pressed to thereby execute processing corresponding to the function key, and an NC program for hole machining is created using data inputted while referring to the dialog screen.
A dialog-type numerical control apparatus of this kind, which will be described with reference to FIG. 9, successively displays predetermined dialog screens on a display screen in accordance with the following steps: workpiece material and coordinate systems; "MACHINING DEFINITION", "NC DATA CREATION", "END", etc.); drilling, etc.); of drilling; regard to a defined hole shape;
An operator responds to the dialog screens by entering the necessary data from a keyboard. Finally, an NC program (NC data) for hole machining is created using the entered data.
By way of example, in a case where a drilled hole (displayed in the form of a solid line) shown in FIG. 10 is machined, the drilled hole is selected from preregistered hole types and hole dimensions (hole diameter D and depth L) are decided at the fifth step, whereupon the machining processes [e.g., "PROCESS 01: CENTER DRILLING" (displayed in the form a broken line), "PROCESS 02: DRILLING"] are automatically decided by the system. Thereafter, if hole position is defined at the seventh step and NC data creation is designated, NC data for drilled hole machining will be created automatically.
However, in the conventional dialog-type input automatic programming apparatus, hole machining NC data can be created in accordance with the foregoing steps using only the predetermined hole types and machining procedures. Consequently, if it is desired to create NC data for machining a hole having an arbitrary hole shape not registered in advance, the operation for creating the NC data is a troublesome one. For example, a hole shape HOL shown in FIG. 11 has an arbitrary shape which is a combination of a spot facing hole SPF and a drilled hole DRL. In order to create NC data for machining this hole shape HOL, it is necessary with the conventional practice to repeat the processing of the fourth to seventh steps with regard to the spot facing hole SPF and again with regard to the drill hole DRL. As a result, a great amount of time is required for the data creating operation.
Accordingly, an object of the present invention is to provide a hole machining NC data creation method whereby any hole shape or machining procedure can be added or modified as a hole type, and NC data for machining a hole having any hole shape can be created with ease by specifying the hole type.
SUMMARY OF THE INVENTION
In the method of the invention for creating NC data for hole machining, any hole shape pattern and a machining procedure thereof are entered in dialog fashion and these are registered as a single item of hole-type data in a hole-type registration mode. In a case where the registered hole type is designated as the hole type in the creation of NC data for hole machining, a dialog screen conforming to the hole type is displayed using the hole-type data, and hole machining NC data is created using hole shape dimensions, tools used, etc., entered in accordance with the dialog screen .
