There are provided a first machining method in which a tool (TL) is fed a predetermined amount (d) in a center direction of a blank to cut into the blank, after which the tool is fed in a cutting mode by an amount (W) corresponding to groove width longitudinally of the blank to perform grooving, and a second machining method in which the tool (TL) is fed in the center direction of the blank to perform machining down to the groove bottom (GB), after which the tool is raised to perform grooving. Based on data indicative of the shape of the tool used, it is decided whether to perform grooving down to the designated groove bottom (GB) by repeating the first machining method or perform grooving to a designated groove width by repeating the second machining method.

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.

The present invention provides a method of editing NC programs for a four-axis lathe for creating NC programs that make possible simultaneous machinining by two tool rests. In order to raise machining efficiency, the machining speed is adjusted between the NC programs edited for each tool rest or an adjustment is performed by altering machining sequences or by resetting them in such a manner that the machining sequences are executed simultaneously. This facilitates modification of machining speed, resetting of machining sequence, etc.

A conversational-type programming apparatus according to the invention originates an NC tape for a numerically controlled (NC) machine tool or the like. In a case where a plurality of machining operations are defined for one region of a blank, a color corresponding to a type of machining designated by the latest machining step is displayed on a screen. Therefore, even when a machining operation for the same blank is defined for a plurality of regions of the blank, it is possible to readily distinguish the machining type designated for each region based on the displayed colors of the regions.

When round screw thread machining is performed with a tool (TL) having a radius smaller than a circular arc radius of a threaded portion (RST), data necessary for deciding (i) tool path patterns of round screw threading cycles (PLi) and (ii) a starting point (Pi) of each round screw threading cycle are commanded and incorporated in NC command data of the round screw threading cycles, the cycle starting point (Pi) of each round screw threading cycle (PLi) is obtained along the circular arc profile of the round screw thread using the data, and round screw thread machining is performed by repeatedly executing the threading cycles while successively shifting the cycle starting point.

Comment statements (CMS1, CMS2) are inserted after T-codes (TC1, TC2) for tool selection in an NC machining program (1) created conversationally. The comment statements including information relating to tools in the T-codes and/or information relating to a machining processes performed by the tools.

A method for inputting a part profile which includes a standard or repeating shape. If a pattern profile input is requested at the time of a part profile input operation, a profile menu is displayed in a software key area (13b). When a pattern profile is selected by the profile menu, the selected pattern profile, e.g., a pattern view (CGP) of a series of grooves is displayed in conversational screen display area (13a) and a message (DQS) calling for various dimensions is displayed. The profile of the series of grooves is specified based on data entered in response to the message.
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.

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.
