Abstract
The method of the invention includes displaying a profile outline (POL) and a graphic cursor (CSR) on a display screen, adopting points, which are obtained on the display screen by successively positioning the graphic cursor and inputting its coordinates at starting points and end points of linear cutting or circular arc cutting, displaying a tool shape (TL) having a designated diameter at the inputted points, displaying a tool path (TLP) by successively connecting the inputted points by straight lines or circular arcs, and creating an NC program for moving a tool along the tool path to perform pocket machining.
Claims4
A method of creating a numerical control program for pocket machining of a workpiece in which the interior of a profile outline is machined by a series of cuts along at least one of straight lines and circular arcs, comprising the steps of:
- (a) displaying the profile outline and a graphic cursor on a display screen;
- (b) displaying a grid on the display screen, overlaying the profile outline, the grid formed of squares having sides with a length corresponding to a tool diameter;
- (c) inputting points, by successively positioning the graphic cursor and inputting the coordinates of the graphic cursor at a starting point and end point of one of the straight lines and circular arcs,
- (d) displaying a tool shape, having the tool diameter, at the starting and end points,
- (e) displaying a tool path by successively connecting the starting and end points using the one of the straight lines and circular arcs;
- and
- (f) creating a numerical control program for moving a tool, having the tool diameter, along the tool path to perform pocket machining.
