NC data creation method
First Claim
1. A numerical control data creation method through which numerical data are created by previously registering, for each and every tool, a tool data file including names of machining processes using the tool and tool shape data indicative of the tools, then deciding machining processes necessary for obtaining a finished shape and selecting a predetermined tool from among tools registered as tools used in the machining processes, said method comprising the steps of:
- (a) including in the tool data file of each and every tool a tool data rotation direction for that tool;
(b) outputting a tool selection command for selecting a predetermined tool, and a command for rotating the spindle in a spindle rotating direction conforming to the tool data rotation direction included in the tool data file of the predetermined tool; and
(c) setting, prior to performing step (b), a parameter indicating whether the spindle rotating direction is determined in dependence upon the machining processes or in dependence upon the tools used.

Abstract
The rotating direction of a spindle is stored in a tool data file storage area (101b) for each and every tool used.
Data necessary for creating an NC program are stored in a RAM (105) conversationally using an operator'"'"'s panel (108) and graphic display unit (102). Thereafter, a processor (103) creates the NC program using the data stored in the RAM.
When a tool used in a predetermined machining process is decided during the creation of the NC program, a tool selection command for selecting the tool is outputted and, in addition thereto, a spindle rotating direction conforming to the selected tool is obtained from the tool data file storage area (101b) and a spindle rotating command for rotating the spindle in said direction is outputted.

4. A method of creating numerical control data comprising the steps of:
-
(a) storing a tool data file for each tool, the tool data file including names of machining processes using the tool, tool shape data and a spindle rotating direction; (b) determining the machining processes necessary for obtaining a finished shape; (c) outputting a tool selection command for selecting one tool from among a plurality of tools used in the machining processes determined in step (b); and (d) outputting a command for rotating the spindle in a direction conforming to the tool selected by the tool selection command output in step (c).
