摘要： A method of compiling NC programs for a four-axes lathe, to prepare NC programs that make it possible to carry out the machining on two tool rests simultaneously. To increase the machining efficiency, the machining speed is adjusted between the NC programs that are compiled for each of the tool rests, or the orders of machining are rearranged, or the machining operations are carried out simultaneously, by means of soft key function of MDI/CRT, so that the machining speed can be easily changed or the orders of machining are easily set again.

摘要： A system for automatically drawing the profile of a tool comprises a memory means (6) which stores a processing program in the form of a dialog and a tooling file used as tool data, data input means (3) which inputs processing data, control means (1) which selects the most suitable tool depending upon the designated processing data such as portions of a work to be processed and a shape to be processed, and an image display means (4) which draws the profile of the tool that is selected. The image display means (4) automatically draws the shape of a material, the shape to be processed and the shape of the tool.

摘要： An interface method employed in a numerical controller to perform high-speed interface for signal interchange between the microprocessor of the numerical control unit and the microprocessor of a programmable machine controller. When an M-code is read from the numerical control program, the processor in the numerical control unit sends the M-code to a latch circuit in the interface circuit to store it in the latch circuit and inverts the logic level of a first status signal (MF) in a corresponding bit region of a first register in the interface circuit. Thereafter, when the controller finishes the sequence control related to the M-code, the processor in the controller inverts the logic level of a second status signal (MFIN) in a corresponding bit region of a second register in the interface circuit. When the first and second status signals coincide, the processor in the numerical control unit starts to process the next block in the numerical control program. Therefore, high-speed interfacing is possible.

摘要： A system for controlling the tapping operation in which the turning of tap is effected by a digital spindle motor (1) in synchronism with the drive of tap in the axial direction by a servo motor (2) for tapping operation of high accuracy and high reliability. A speed instruction is supplied from a position control means (4) to a digital control circuit (5) which drives a spindle motor, the speed instruction being based upon a distribution pulse from an interpolation circuit (3a) which performs linear interpolation depending upon the pitch of a screw that is to be machined and upon a feedback signal that represents the rotational position of the spindle motor. The distribution pulse is further supplied to a servo circuit (12) for the servo motor from the interpolation circuit. Therefore, the two motors are driven in synchronism with each other. In one embodiment, the tapping operation is effected according to a fixed cycle in which the two motors are turned forward and reverse repeatedly to reciprocate the tap. In another embodiment, a switching means (7) to supply the distribution pulse and the feedback signal intermittently is provided in order to selectively perform the tapping operation.

摘要： Numerical controller wherein execution format data necessary for a particular C-axis machining function such as read machining are prepared by a custom macro stored in a ROM (102) from data that are set by an operator using data setting means such as a keyboard (104). High-speed distribution data for controlling a machine tool are prepared, as required, by setting parameters like those that are used for ordinary turning operations, and a particular machining function is realized that requires high-speed interpolation to instruction data for moving the machine.

摘要： In a locus drawing system, the designation of colors is done by a black base frame background color (a) and three-color bit patterns (R, G, B) to draw a static image including a region to be processed, and a locus. Colors are designated in a manner that a color (b) in which the static image is displayed and a color (e) in which the region to be processed is displayed are complementary colors to each other, to display the static image, which is superposed on the region to be processed, in black, which is the same color that is designated as a background color (a), and a locus in a color (c) which is in agreement with the color (e) of the region to be processed.
