Disclosed is a method and apparatus for machining a workpiece (2). The method comprises specifying a path along which a cutting tool (6) is moved during machining the workpiece (2), the path comprising segments (26); defining, for each segment (26), an exit point on that segment (26); defining, for each segment (26), an exit path (38) from the exit point of that segment (26) to a point remote from the workpiece (2); performing a machining process including moving the cutting tool (6) along the tool path and machining the workpiece (2); and, during the machining process, when one or more criteria are satisfied: interrupting the machining process and, without machining the workpiece (2), moving the cutting tool (6) to the exit point of the current segment (26) and then along the exit path (38) of the current segment (26).
摘要:
A numerically controlled machine tool which allows the automatic generation of a restoring program for carrying out processing required for the resumption of an NC machining program to resume the execution of the NC machining program after the execution of the NC machining program has been stopped and interrupt processing has been performed. Specifically, even for nesting programs, when the machining program is re-executed from where it had stopped after the execution of the machining program has stopped and the operator has performed optional interrupt processing, the stop-time and re-execution-time machine statuses are compared to automatically generate the restoring program so that the machine status may be returned to the stop-time status, whereby the operator can perform the resumption processing of the machining program without any restrictions.
摘要:
A method of controlling a dispensing system, having a robot that moves along a motion segment and applies a material to a workpiece, automatically determines a backup distance for the robot after an error has occurred during the dispensing of a first portion of the material. The backup distance is based on an operational speed of the robot. The robot is relocated to a backup position based on this backup distance to ensure that the robot reaches the operational speed at least by a time that the robot reaches a re-application position. The re-application position is at or near where the application of the first portion of the material ended. Therefore, gaps, overlaps, and puddles in the material on the workpiece are prevented.

According to a method according to the invention for designating and/or controlling a manipulator process for a manipulator configuration (1, 2, 3) having at least one manipulator, in particular, an industrial robot, wherein the manipulator process exhibits a given oriented manipulator track for the manipulator configuration, at least one action by the manipulator configuration can be designated, or shall be executed, respectively, in particular, differently, in relation to a reverse movement running counter to the oriented manipulator track, and/or a return movement running in the same direction as the oriented manipulator track.
摘要:
In a wire-cut discharge machine, a workpiece fixedly mounted on a movable table is returned from the present position to a machining start position so that auxiliary objects, such as clasps for holding the workpiece, and structural objects, such as the nozzle of the wire-cut discharge device, do not interfere with each other. Relative coordinate values between the machining start position and the present position are calculated and the calculated results are displayed on a display device. The workpiece is moved in an X-direction and is then moved in a Y-direction toward the machining start position based on moving data corresponding to the calculated results.
摘要:
A numerical control contouring system in which successive path segments are executed according to successive blocks of command signals making up a path program, the system being interruptable at any time by a feedhold signal to stop the controlled movable member at a random point on the path. The system is characterized by the improvement of preventing the system from resuming normal operation unless and until the member is returned to the path stopping point after it has been, for any reason, displaced therefrom under manual control or the like. In one embodiment, the axis component displacements of the member from the stopping point are represented by signals created and displayed, and the operator's restart pushbutton switch is rendered ineffective until the displayed displacement signals are reduced to zero. In another embodiment, the axis component displacement signals are utilized to create a non-program block of command signals, and means responsive to a restart signal first cause the member to be moved back to the path stopping point before the system is automatically restored to normal operation. In a third embodiment, after each movement of the controlled member following its arrival at the stopping point, the axis components for that movement are signaled and stored, and means responsive to a restart signal first utilize such stored signals to execute such movements in reverse order and senses to return the member to the path stopping point, and next restore normal operation of the system so that movement along the path is resumed.

An on-line data processing machine controls the operation of one or more machine tools. A general purpose communications link allows each machine tool and/or the operator therefore to communicate with the data processing machine and either change the operations which the machine tool would otherwise perform under control of an existing stored program, or add new or partly new operations, which if desired can thereafter immediately be performed by the machine tool.

Disclosed is a method and apparatus for machining a workpiece (2). The method comprises specifying a path along which a cutting tool (6) is moved during machining the workpiece (2), the path comprising segments (26); defining, for each segment (26), an exit point on that segment (26); defining, for each segment (26), an exit path (38) from the exit point of that segment (26) to a point remote from the workpiece (2); performing a machining process including moving the cutting tool (6) along the tool path and machining the workpiece (2); and, during the machining process, when one or more criteria are satisfied: interrupting the machining process and, without machining the workpiece (2), moving the cutting tool (6) to the exit point of the current segment (26) and then along the exit path (38) of the current segment (26).

Disclosed is a method and apparatus for machining a workpiece (2). The method comprises: specifying a path along which a cutting tool (6) is to be moved during machining of the workpiece (2), the path comprising a plurality of segments (26); defining, for each segment (26), an entry point and an entry path (32) from a point remote from the workpiece (2) to that entry point; moving a first cutting tool (6) along the tool path from a first point to a second point and machining the workpiece (2); after the first cutting tool (6) has been moved to the second point, moving the first cutting tool (6) to a point remote from the workpiece (2); moving a second cutting tool (18) along the entry path (32) of the segment (26) that contains the second point, and then from the entry point to the second point.
