Abstract
Abstract A contour configuration machining system of an interactive numerical control apparatus is provided for carrying out a machining operation by a lathe by programming a predetermined contour configuration based on configuration data of straight lines, arcs and the like. A cutting direction (9) is independently set on a display (1) for each of the above configuration data and the machining operation is carried out by moving a tool according to the set cutting direction, whereby the machining efficiency is improved when a configuration composed of a series of contours is to be machined.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
90 words
A contour configuration machining method of an interactive numerical control apparatus for carrying out a machining operation by a lathe by programming a predetermined contour configuration based on configuration data of straight lines, arcs and other data, comprising the steps of: (a) storing with each of said configuration data optimally efficient tool cutting direction information for a tool associated with said configuration data; and (b) carrying out the machining operation by moving the tool according to the optimally efficient tool cutting direction information stored with each of said configuration data.
Claim 2
Dependent Claim
90 words
A contour configuration machining method of an interactive numerical control apparatus for carrying out a machining operation by a lathe by programming a predetermined contour configuration based on configuration data of straight lines, arcs and other data, comprising the steps of: (a) storing with each of said configuration data optimally efficient tool cutting direction information for a tool associated with said configuration data; and (b) carrying out the machining operation by moving the tool according to the optimally efficient tool cutting direction information stored with each of said configuration data.
Claim 3
Dependent Claim
44 words
A contour configuration machining method according to claim 1, wherein the optimally efficient tool cutting direction information indicates one of a forward direction and a reverse direction with respect to a direction from a start point to an end point of said configuration data.
Claim 4
Dependent Claim
31 words
A contour configuration machining method according to claim 1, wherein said machining operation is carried out by a machining process divided into subprocesses each based on one of said configuration data.
Claim 5
Dependent Claim
80 words
A contour configuration machining method according to claim 1, wherein step (b) comprises, when a coordinate at a point at which a machining process has been completed does not coincide with a coordinate of a start point for machining of a next machining process according to the optimally efficient tool cutting direction information, performing a quick feed of said tool to a predetermined auxiliary point and then said tool is moved to said start point of said next machining process.
