BRIEF SUMMARY
DESCRIPTION
1. Technical Field L This invention relates to an NC data creation method and, more particulary, to an NC data creation method in which a command statement is inserted after a T-code for tool selection.
2. Background Art
An automatic programming system is available in which a conversational screen conforming to each step of a plurality of data input steps is displayed on a display unit and NC statements (NC data) executable by an NC unit are created using data entered while referring to the conversational screens. For example, see U.S. Pat. No. 4,723,203 ("Machining Process Determination Method in Automatic Programming"). Such an automatic programming system includes the following steps, which will be described with reference to FIG. 6: next) and statement).
In accordance with these steps, predetermined prompts (conversational screens) are successively displayed on a display screen, the operator enters the required data from a keyboard in response to these prompts and finally an NC statement is created using all of the entered data. It should be noted that the conversational inputs from the ninth step to the 14 step are made repeatedly until all machining process data have been entered.
The NC statement created by the foregoing method has NC statements MP1, MP2, ... MPn (see FIG. 7) for machining processes entered in sequence by repeating the ninth through 14th steps. Specified in each NC statement for a machining process are NC data (G50X.sub.-- Y.sub.--) for setting a coordinate system, a T-code (T.sub.--) for selecting a tool, and NC data (G01X.sub.-- Y.sub.-- ;..) for a tool path.
With this conventional NC statement format, however, it is difficult to tell merely from looking at the NC statements what tool is being used for what process; hence, checking and revising the NC statements is not easy. Further, the tool number.sub.-- in the T-code (T.sub.--) for tool selection indicates the tool position on a turret on which a plurality (six to ten) tools are mounted. Since it is not known whether the same tool will always be mounted at the same position on the turret, one cannot immediately tell merely from looking at the T-code of the NC statement what the tool is.
SUMMARY OF THE INVENTION
Accordingly, an object of the present invention is to provide an NC data creation method wherein the type of a tool, the process in which the tool is used, etc., can be recognized merely by looking at an outputted NC statement, and wherein it can be readily ascertained what part of an NC statement is for a machining process and what the process is.
In an NC data creation method according to the invention, a comment statement is inserted after a T-code for tool selection, the comment statement including information relating to a tool in the T-code and/or information relating to a machining process performed by the tool.

DESCRIPTION OF THE PREFERRED EMBODIMENT
FIG. 1 is a view for describing the general features of the present invention.
Numeral 1 denotes an NC statement, MP1, MP2, ... represent NC statements for respective machining processes, TC1, TC2 designate T-codes for selecting tools, and CMS1, CMS2 denote comment statements.
The comment statements CMS1, CMS2 are inserted after the tool selection T-codes TC1, TC2 of the NC statement 1 created based on data entered via a plurality of data input steps, each of the comment statements CMS1, CMS2 comprising information relating to the tool of the T-code and/or information relating to the machining process performed by the tool. This information is enclosed in brackets.
