Abstract

PURPOSE:To simply edit the tool path by displaying an arbitrary shape of a work and the tool path generated automatically on a graphic display screen, and editing the displayed tool path by changing, deleting and adding it on the screen. CONSTITUTION:On a display screen 1, an island 3 and a pond 2 of a work are brought to graphic display, and the pond 2 is brought to pocket working by a tool 4. Such a tool path 5 is determined automatically, when a shape of the work, that is, an outer wall 3a of the island 3 and an inner wall 2a of the pond 2 are determined. In this regard, in case it is necessary to edit the tool path 5, a point on the tool path 5 to be edited is selected, and a position of an editing point is changed. Also, in accordance with necessity, the point on the tool path 5 is added or deleted, and the edited tool path 5 is displayed. In such a way, the tool path 5 determined automatically is brought to graphic display, and also, the tool path 5 can be edited directly on the graphic display.

FIG. 2 is an explanatory diagram of how the tool path is automatically determined. The work island 3 and pond 2 are graphically displayed on the display screen. The hatched portion is the portion that will not be processed, and the remaining pond 2 is pocket processed using the tool 4. Such a tool path 5 is automatically determined once the shape of the workpiece, that is, the outer wall 3a of the island 3 and the inner wall 2a of the pond 2 are determined.

For example, we decide to approach the tool 4 from the lower right, advance the tool in the X-axis direction after the approach, move it in the Y-axis direction by about 75% of the tool diameter at the part that hits the inner wall 2a of the pond,
It is sufficient to proceed in the negative direction of the X-axis, and once it hits the inner wall 2a of the pond, proceed in the direction of the Y-axis.

Initially, all the meshes in pond 2 are set to O, and the other meshes are set to 1. Next, the mesh of the pond 2 through which the tool 4 passed is changed from 0 to 1. Therefore, when all the meshes in the pond 2 become 1 due to the meshes of the tool, it means that all the machining has been performed, and the tool path 5 is completed.

FIG. 3 is a diagram showing the arbitrary shape of the workpiece and the tool path on the display screen. In the figure, a part of the inner wall 2b of the pond 2 protrudes, and therefore a part of the tool path 5 is changed. Note that the changed portion of the tool path 5 is shown in an exaggerated manner for easy understanding. That is, the tool path 5 is changed from passing through points P1 and P2 to proceeding in the Y-axis direction at point P3 and proceeding in the positive direction of the X-axis at point P4.
