BRIEF SUMMARY
DESCRIPTION
1. Technical Field
This invention relates to an angle data discriminating method in an NC machining data creation method. More particularly, the invention relates to an angle data discriminating method in a method of creating NC machining data by entering a direction for each block of a part profile through use of profile symbol keys thereby to specify the part profile (exclusive of dimensions), followed by specifying the dimension of a straight line element in a predetermined block of the part profile by data including at least an angle of intersection between the straight line element and a base line, and using these entered data to create the NC machining data.
2. Background Art
Automatic programming systems for lathes have come into practical use and are used to create NC tapes from a design drawing through a simple operation by entering data in a conversational mode using a graphic display screen. With such an automatic programming system, a part profile can be entered merely by pressing profile symbol keys, which are located on an operator's panel, corresponding to a workpiece (part) profile written on a design drawing. Further, according to the automatic programming system, referential information is graphically displayed on the screen from time to time and inquiries are made in ordinary language, so that dimensions and various data can be entered in response to the inquiries. When all data necessary for creation of an NC tape have been entered, the blank profile and the finished profile are immediately displayed on the display screen, automatic calculation of NC command data begins and a tool path is graphically displayed to create an NC tape. A programming method performed by such an automatic programming system will now be described in detail. The method comprises the following steps: to eventually create the NC tape. In the third step for entering part profile and dimensions, coordinate axes and the blank profile, as well as a part profile inquiry, are displayed on the screen, one responds to the inquiry, while observing the design drawing, by pressing a profile symbol key on the keyboard in accordance with the profile on the design drawing, thus to enter the part profile (exclusive of dimensions). Following the entry of the part profile, the display screen makes an inquiry requesting the necessary dimensions, and dimensions taken from the design drawing are entered from the keyboard in response to the inquiry, thereby completing the entry of a part profile and its dimensions. As an example, if the part profile has the shape shown in FIG. 1, then, in entering the part profile, predetermined profile symbol keys (keys indicated by the symbols .uparw., , .fwdarw., , .dwnarw., , .rarw., , , ), shown in FIG. 2 and provided on a keyboard 104, are pressed in accordance with the direction of each block. Specifically, a straight line element L.sub.1 in a first block b.sub.1 is directed horizontally (Z axis) rightward, a straight line element L.sub.2 in a second block b.sub.2 is directed vertically (X axis) downward, straight line elements L.sub.3 and L.sub.4 in third and fourth blocks b.sub.3 and b.sub.4 are directed downwardly toward the right, and a straight line element L.sub.5 in a fifth block b.sub.5 is directed downward. Therefore, entry of the part profile will completed if the symbolic keys are pressed in the order numerical value input keys automatically in dependence upon the automatic programming process steps, and it becomes possible to enter the letter of the alphabet shown at the lower right of the key tops when a shift key is pressed.
Next, dimensions of the line elements in each of the blocks b.sub.1 -b.sub.5 are entered in response to inquiries from the drawings. Specifically, first block, the value of the diameter at the end point of each block, A denotes the angle (in which the counter-clockwise direction is taken as the positive direction) which the straight line element makes with the horizontal axis, and L designates the length of the straight line element along the Z a
