Abstract
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.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
163 words
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.
Claim 2
Dependent Claim
163 words
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.
Claim 3
Dependent Claim
94 words
The numerical control data creation method according to claim 1, wherein said outputting in step (b) includes the steps of: (bi) referring to the parameter to distinguish between machining process-dependence and tool-dependence when outputting the tool selection command; (bii) obtaining the tool data rotation direction of the predetermined tool from the tool file in a case where the spindle rotating direction is dependent upon the tools used; and (biii) outputting the spindle rotating command for rotating the spindle in the tool data rotation direction obtained in step (bii), together with the tool selection command.
Claim 4
Dependent Claim
110 words
The numerical control data creation method according to claim 2, further comprising the step of (d) storing, prior to performing step (b), a correspondence table indicating correspondence between each of the matching processes and a correspondence table rotation direction, and wherein said outputting in step (b) further comprises the steps of: (biv) obtaining, in a case where the spindle rotating direction is determined in dependence upon the machining processes, the correspondence table rotation direction of a current machining process from the correspondence table; and (bv) outputting, together with the tool selection command, the spindle rotating command for rotating the spindle in the correspondence table rotation direction obtained in step (biv).
Claim 5
Independent Claim
102 words
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).
Claim 6
Independent Claim
102 words
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).
