    摘要: PURPOSE:To enable highly accurate combination of phase without making a zig by providing an operating circuit for determining the original point offset from C-axis measurement memory and C-axis command memory thereby automatically controlling C-axis original point offset. CONSTITUTION:Upon provision of ideal positional data PRA of the referential machining face from NC program 7, a function generator 9 will generate a function signal SG to drive C-axis motor 12. It is predicted that the actual measuring position is between the positions 2A, 4A to rotate in said interval while searching through cutting feed and upon contact of a touch sensor 6 against the position Ps on the referential machining face, a signal SS is provided to the circuit 9 thereby C-axis motor 12 will rotate reversely to perform such functional operation as to return to the starting position 1A while since the signal SS will cause opening of a gate 15, the C-axis positional data ST upon contact of the sensor 6 against the referential machining face is stored in a measurement memory 16 to output the data MA to the operating circuit 17 while to set the value MC operated for the ideal value MB into the memory value 18 thus to determine the C-axis original point offset value.

    摘要: PURPOSE:To attain original positioning work easily for a short time by supplying electric power to an NC control motor, detecting an original signal outputted from the motor and fixing a motor shaft at the turning position of the original point. CONSTITUTION:The NC control motor 10 is connected to an original point checking device 14 at first. Consequently, 5V power supply is applied from the device 14 to the motor 10, and if the rotary shaft of the motor 10 is rotated manually under said state, pulse-like A-phase, B-phase and original point signals are formed in the motor and impressed to display lamps 22, 24, 26 through level conversion circuits 16, 18, 20 respectively. When the shaft 10a is rotated slowly by a hand, the original point signal appears on the original position and the lamp 26 lights up, so that a shaft 12a is fitted to the NC device. The frequency of the generation of A-phase or B-phase signals in each rotation of the motor is displayed on a display device 36 and the abnormality of a pulse generating part or the like of the motor 10 can be detected.

    摘要: PURPOSE:To dispense with transfer for aligning the position of a work by measuring errors between both coordinate systems after approximately locating the work and incorporating the error value in a program of NC machine, in other words, the conversion of coordinate. CONSTITUTION:In a position aligning method when a NC machine tool is used in a ship-building yard and iron works, related apparatus are constituted from a work 1, a NC machine tool 2 and rails 3 on which the machine tool 2 travels, and the machine tool 2 travels in the direction perpendicular to the surface of the drawing. Assuming this direction be the direction of axis X for example, a working head 2a moves on the machine tool 2 in the direction parallel to the surface of paper, i.e. the direction of axis Y and a television camera is mounted on the working head. The related apparatus has further a control panel 2b, a receiver for the television camera and a reader 5 for reading transfer distance of the machine tool 2, and the output of the reader 5 is sent to the input of the panel 2b as a coordinate converting numeral. Thus, the transfer for aligning the position of the work can be dispensed with.

CONSTITUTION:An angle detector 3 is connected to a shaft 2 which interlocks a main can 1 to obtain the angle information. At the same time, the original point information detected by a photoelectric switch 5 and an original point detector 6 is supplied to a cycle timer device 4 to be stored there. For this control, a central processing unit CPU8 stores the original point information to a nonvolatile memory 10 based on a control program on the device 4 which is stored in a fixed memory 9 and the angle information on a machine. This stored angle information is compared with the angle information given from the detector 3. Then the control data is delivered to a controller 7.

CONSTITUTION:The coordinate values of the fixed position S of an end surface fixing device 35, which is attached to a head 20, with respect to an original point Q of a machine are set. The table 21 supports the center of a master work Wm having an outer diameter (d) at a circular cylinder surface. The amount of movement of the table 21 with respect to an original point Q is detected, and a size (d) is inputted into a numerical control device 40. Then the table 21 is moved. A present position Z1 of the table under the state the end surface of the work Wm is positioned at S is stored in a memory 41. The table 21 and a grindstone stand 27 are positioned so that the end surface and the cylinder surface of the work Wm are contacted with the end surface and the cylinder surface of the grindstone. A present position Z2 of the table under this contact state is read. Based on the size (d) and the value z1, an expression, z1-z2-d/2tantheta is operated, and the result is stored in the parameter area of the device 40.

    摘要: PURPOSE:To enable the measurement of the diameter of a hole as a boring quill remains inserted in a main shaft, by protruding a pair of contact pins for the measurement of the diameter of the hole, in positions nearer to the butt of the quill than to a cutting tool. CONSTITUTION:A pair of contact pins 43, 43 for measuring the diameter of a hole are protruded from the peripheral surface of the tip of the tool mounting part 16 of a boring quill so that the pins are located nearer to the butt of the quill than to the cutting edge 25 of a cutting tool 26. To measure the diameter of the hole, the quill is displaced in the direction (downwards) of extension of a first plane 44 oppositely to the cutting edge 25, away from the state of cutting in which the axis O2 of the tool mounting part 16 of the quill and that O1 of the hole of a work W are coincident with each other, so that a third surface plane 46 or the straight line extending between the axes of the contact pins 43, 43 coincides with the axis O2 of the hole. The pins 43, 43 are then horizontally displaced in the direction (rightward of leftward) of extension of the third plane 46 so that the pins are brought into contact with the inside surface of the hole.
