A machining process determination method in automatic programming for automatically creating NC data for a lathe. The method includes storing machining processes in a memory in a machining sequence, reading the previously stored machining processes out of the memory in order after entry of a blank profile (BP) and part profile (PF); automatically discriminating based on the blank profile and final part profile whether the read machining process is needed to obtain a final part; when it is not required, performing identical discrimination processing upon reading the next machining process out of the memory, and when it is required, determining a cutting domain (A1, A2, A3) and cutting direction of the machining process; and thereafter creating NC data upon reading subsequent machining processes out of the memory and performing identical processing.

There is provided a numerical control unit having a processor (102a), a control program memory (102b), a memory (102c) for storing files, and input means (102d) for accessing the files. The processor (102a), in accordance with the control program, processes externally entered control data to numerically control a machine connected thereto. The arrangement is such that the name of a file to be protected is stored in the memory (102c) of the numerical control unit and, the name of an object file is compared with the protected file name in the memory (102c), when a modification command and the name of the object file are entered from the input means (102d). Processing for modifying the file is executed, on the condition that there is a processing confirmation input from the input means (102d), when the object is a file protected file.

A blank profile specifying method in automatic programming for lathes has a step of specifying a finished profile (1), a step of entering a maximum length (L.sub.m) and a maximum diameter (F.sub.m) of a blank profile (2), a step of obtaining the maximum length (L.sub.t) and the maximum diameter (F.sub.t) of the finished profile from entered finished profile data, a step of calculating an uncut thickness (t.sub.z) longitudinally of the blank and an uncut thickness (t.sub.x) diametrically of the blank by using L.sub.m, L.sub.t, F.sub.m, F.sub.t, a step of obtaining the blank profile (2) by enlarging the finished profile by the uncut thicknesses in the respective directions, and displaying the blank profile and the finished profile, a step of entering position data indicative of inflection points (P.sub.1, P.sub.2 . . . P.sub.5) of an actual blank profile, and a step of storing the entered position data indicative of the inflection points and modifying the display of the blank profile by using the position data.

A color display method for a system having an automatic programming unit (101) equipped with a color display function, and an NC unit (102) which does not possess a color display function, wherein a correlation between a display item and a display color for an NC mode of operation is stored beforehand in a memory (105c) of a control unit (105). When a predetermined item display request key provided on an operator's panel (104) is pressed while in the NC mode, a control unit (105) informs the NC unit (102) of the name of the item for which display has been requested and applies color information, which corresponds to the item for which display has been requested, to a color display device (106). The NC unit applies item data, corresponding to the name of the item, to the color display device which displays the item data in a color designated by the color information applied thereto by the control unit (105).

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.

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.

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.

The rotating direction of a spindle is stored in a tool data file storage area (101b) for each and every tool used.Data necessary for creating an NC program are stored in a RAM (105) conversationally using an operator's panel (108) and graphic display unit (102). Thereafter, a processor (103) creates the NC program using the data stored in the RAM.When a tool used in a predetermined machining process is decided during the creation of the NC program, a tool selection command for selecting the tool is outputted and, in addition thereto, a spindle rotating direction conforming to the selected tool is obtained from the tool data file storage area (101b) and a spindle rotating command for rotating the spindle in said direction is outputted.

A method and apparatus for controlling an electric discharge machine wherein a motor for moving an energized electrode relative to a workpiece is driven in accordance with command data. The method includes the steps of storing in a memory retraction control information contained in the command data, moving the electrode in an advancing direction relative to the workpiece by controlling the speed of the motor in accordance with machining feed speed information contained in the entered command data, monitoring the current position of the electrode by counting, via a counting device, pulses generated by a sensor whenever the motor rotates by a predetermined amount, moving the electrode in the retracting direction relative to the workpiece by reading in retraction speed from the retraction control information stored in the memory and controlling the speed of the motor on the basis of the retraction speed, when a signal indicative of a short circuit is generated, and moving the electrode in the advancing direction relative to the workpiece by reading in a re-advancing speed from the retraction control information stored in the memory, when a signal indicative of an end to the short circuit is generated.
