摘要： An animated plotting method in which an actual machining action is accurately simulated even if a tool rest is moved to another main spindle not directly associated therewith for cutting, or a single workpiece loaded on a main spindle is subjected to cutting operations by means of a plurality of tool rests. By virtue of a range specification command G10 for specifically setting a plottable range of each tool rest, a plottable range is imparted to each of the tool rests (S3, S4), and then the plottable range for each of the tool rests is displayed on either the left half (13a) or the right half (13b) of the display screen (13) depending on the operating position of each tool rest, or depending on whether each tool rest lies on the side of a first main spindle (14) or on the side of a second main spindle (16), thereby accurately simulating a path of the tool performing an actual machining operation and the state of cutting.

摘要： Disclosed is a numerical control (NC) sentence creation system for creating an NC sentence for a two stage drilling operation by which a hole drilled by a first stage drilling operation is further drilled by a second stage drilling operation using a second drill having a smaller diameter, wherein machining configuration data are input (S1), machining condition data including a first amount of clearance and a second amount of clearance are input (S2, S3), and an NC sentence is created. The NC sentence enables the hole to be drilled in the first stage drilling operation and the second drill for the second stage drilling operation to be moved by a cutting feed from the bottom of the hole drilled by the first stage drilling operation to the machining end point of the second stage drilling operation (S4), whereby a machining time for the second stage drilling operation is shortened.

摘要： The invention relates to a part profile input method for inputting the profile elements of a part using arrow keys. When inputting a part profile, an angle (A.sub.i) defined by two mutually adjacent profile elements (EL.sub.i, EL.sub.i+1) is computed, and whether the corner is in outside corner or an inside corner is determined by comparing the angle of intersection and a set angle. In case of an outside corner, a preset chamfer dimension (DIM) is displayed. If the dimension is acceptable, an input key is pressed to input the chamfer profile (CF) at the corner portion. In case of an inner corner, a prompt display is presented inquiring whether a rounded profile is to be inserted. If insertion is required, a dimension is inputted and the input key is pressed to input the rounded profile.
