摘要:
A method and an apparatus for numerical control to automatically and repetitively carry out numerical control in compliance with a numerical control program modified by utilizing an override function. Whether a teaching instruction is input or not is discriminated (S1) while a numerical control program is being executed. When it is determined (S2, S6) that the feed speed or the main axis speed override memory instruction is input in the teaching mode, an override value set manually using an override switch is written (S10) onto the end of a block under execution of the numerical control program. When the numerical control program is executed on the next time and thereafter, the override operation is automatically carried out as set manually.

A method and an apparatus for loading a control program in a CNC to execute it. In this method, maintenance such as program debugging can be carried out without the need of exchanging a fixed storage device (3) that stores the control program. More particularly, a correction file is transferred from an external unit to a nonvolatile memory (5), and a required correction file is specified at the time of loading so that the control program corrected based thereupon is loaded onto the control memory (2). Therefore, maintenance is facilitated from the standpoint of CNC software.
摘要:
A control apparatus and a method for operating the control apparatus for an industrial robot in which the robot is capable of performing numerous different tasks without requiring reprogramming, and in which programs can easily be corrected to compensate for changes in the workpiece being handled. The control apparatus includes a programming unit and a robot control unit. Each industrial robot is provided with its own robot control unit, while a single programming unit is shared among plural robot control units. The programming unit is detachably coupled to the robot control unit through a communication cable. The programming unit includes an arithmetic processor, one or more memories, an inputting device and a display, and the robot control unit includes plural program memories for storing plural programs communicated to the robot con. trol unit from the programming unit, an operation control unit for carrying out operations of the robot in accordance with a selected program read from a selected program memory and a mode setting circuit for selecting between a mode of receiving and storing programs and continuous operation mode. Data contained in the operating programs can easily be changed to compensate for a change in the workpiece being handled by an editing process carried out in the programming unit.

A machine tool for machining rotating workpieces at high rotational speeds and, in particular, with multiple tool movements within a revolution of the workpiece (46) comprises a low-inertia high-torque motor (18, 51, 101, 150) having an output shaft (19,52,102,151) and a tool holder (21, 54,108,154) mounted for movement relatively to the motor. A cam (20, 53, 104, 153) or other single element connection drivably connects the output shaft (19, 52, 102, 151) and the tool holder (21, 54, 108, 154) and the motor can be operated by control apparatus to so oscillate the output shaft that the tool is moved rapidly back and forth in phase with the output shaft oscillation and in correspondence with the rotation of the workpiece to perform required machining movements.

A grinding machine comprising a pair of columns (3) erected on a frame (1) facing each other and a support frame (4) fixed between the tops of said two columns (3), wherein a first movement means (16) is provided on said support frame (4) movably in a horizontal direction to allow a reciprocating motion thereof, a second movement means (21) being provided at said first movement means (16) movably in a horizontal direction normal to the movement direction of said first movement means (16) to allow a reciprocating motion thereof, further, at said second movement means (21) a third movement means (3)) being provided movably in a vertical to allow a reciprocating motion thereof, a grinding stone head (48) being attached to said third movement means (37).
摘要:
Amethod of correcting a system program in an automatic programming apparatus which prepares an NC program using data prepared with a predetermined language to specify a path for a tool. The system program is stored in a first external memory medium (FD.) said program consists of a plurality of modules (M, - M z ) divided depending upon the functions and a table (BT) which stores at least the first . positions of each of the modules and the data lengths. In a second external memory medium (FD n ) are stored a latest module (M 4 ' ) and a control program (MRP) which replaces an old module (M,) stored in the first external memory medium by said latest module. The contents of the second external memory medium (FD n ) are stored in the memory of an automatic programming apparatus, the first external memory medium (FD o ) is set to the automatic programming apparatus, the first position of the old module (M,) is retrieved from the table (BT) being controlled by the control program (MRP) stored in the memory, and the latest module (M 4 ') is written from said position to replace the old module with the latest module.
摘要:
Disclosed herein is a method of controlling tool positions in a corrugated board container making plant in which tool positioning data corresponding to the specifications of various containers is stored in a computer provided in a suitable environment isolated from the plant and connected on-line with a control in the plant, the tool positions are adjusted on the basis of the data stored in the computer, and during operation after such adjustments, results of further minute adjustments are inputted into the computer, to successively rewrite the data stored in the computer.
