摘要: Disclosed is a method of screwing a pipe having threads with a different pitch on the outside and inside thereof into an object and assembling the same thereto by using a CNC machine tool. A male thread provided to a spindle is moved to an initial point I and point R by a quick traverse and then moved downward from the point R at a given speed and RPM. More specifically, a pipe is screwed into the object in accordance with the pitch of the thread on the outside thereof and assembled to a female thread of the object. When the male thread reaches a point Z and the pipe is assembled to the female thread of the object, the male thread is moved upward to the point R at a given speed and RPM. More specifically, the male thread is relieved from the pipe in accordance with the pitch of the thread on the inside of the pipe. Only the male thread is moved upward by the movement thereof to enable the pipe to remain engaged with the female thread, whereby the assembly of the pipe to the object is completed.

摘要: A method of correcting a machining program for a numerical control device during an execution of the program is provided. A created machining program, which is stored in a memory (5), is executed for a program check, a single block stop is effected at a portion (2) at which an error is found in the machining program, and the machining program is executed in reverse to a predetermined block (P1). Then the machining program is corrected and executed. Accordingly, it is not necessary to return to the beginning of the machining program for a reexecution thereof, and thus the machining program can be efficiently corrected.

摘要: A pitch error compensating system compensates for a pitch error of a ball screw of a numerically controlled machine tool. A pitch error calculating means (4) reads a present value from a present value register (3), reads pitch error corrective quantities (.epsilon.n, .epsilon.pn) in a corresponding period, and outputs pitch error corrective quantities as pitch error corrective pulses (CP) at equal intervals in the period. The pitch error corrective pulses (CP) are added to interpolated pulses (CP) by an adder (5). Since the pitch error corrective quantities are not outputted all at once, the machine tool moves smoothly, and the quality of the machined surface of the workpiece is improved.

摘要: A gear pitch error correcting system for a numerical control apparatus used for a machine tool including at least one pair of gears provided in a transmission line through which the rotating force of a servomotor is transmitted to a driven member. Gear pitch error correction values for the respective gears, which each correspond to a predetermined gear angle and collectively cover one gear rotation, are stored in a nonvolatile memory. A pitch error computing means (E) refers to a current position register (D), reads out pitch error correction data (14b) corresponding to the current position from the nonvolatile memory, and adds up the data to obtain a superimposed pitch error correction value. The superimposed pitch error correction value and an interpolation pulse from an interpolating means (B) are added together by an adder (C), to obtain a pitch error-corrected output pulse, which is then supplied to an axis control circuit (18). Accordingly, even with a relatively small number of gear pitch error correction values for the individual gears, a gear pitch error correction can be precisely executed in proportion to the superimposing of the gear pitch error correction values.
