摘要： A machining control device for a machine tool reads a machining program for each predetermined reading unit, controls a machining operation of a machine tool based on the read machining program, performs a machining simulation by sequentially reading out the read machining program, and discriminates a buffer state based on the result of the machining simulation. If insufficient buffering is discriminated in the control of the machining operation, control is performed to stop machining on a non-machining path short of the position of occurrence of the insufficient buffering.

摘要： The present invention provides a configuration which enables an improvement in the workability of wiring of a sensor in a servo system. An encoder detects the operation of a motor driven by a servo driver, and generates a feedback signal indicating the detected operation. Further, the encoder receives detected signals output from sensors for detecting an object driven by the motor via sensor cables. The encoder outputs the feedback signal and the input detected signals to the outside.

摘要： A controller that controls a machine tool, a method of controlling a machine tool, and a computer program that causes a computer to operate as a controller that controls a machine tool, the machine tool comprising multiple control axes and used for machining by cutting of a work as a machining target by means of coordinated motion of the control axes. The method includes acquiring a position command for driving a cutting tool or the work, acquiring a rotation speed of the rotated cutting tool or the rotated work, calculating oscillation amplitude, calculating an oscillation frequency, calculating an oscillation command for causing the cutting tool and the work to oscillate relative to each other, storing a command route, correcting the oscillation command based on the stored command route, determining a drive signal to be used for driving the servo motor, and outputting the drive signal.

摘要： The present disclosure relates to systems and processes for controlling the relative positions or phasing of advancing substrates and/or components in absorbent article converting lines. The systems and methods may utilize feedback from technologies, such as vision systems, sensors, remote input and output stations, and controllers with synchronized embedded clocks to accurately correlate component placement detections and placement control on an absorbent article converting process. The systems and methods may accurately apply the use of precision clock synchronization for both instrumentation and control system devices on a non-deterministic communications network. In turn, the clock synchronized control and instrumentation network may be used to control the substrate position. As such, the controller may be programmed to the relative positions of substrates and components along the converting line without having to account for undeterminable delays.

摘要： Systems and methods for automated workflow comprise assigning a set of first targets to an uncompiled first workflow. The uncompiled first workflow specifies a first set of process modules. Each such module is associated with a subset of unit operations. Each unit operation includes a time interval and specifies an instrument. For each target in the set of first targets, the uncompiled workflow is translated into an instance of a compiled first workflow comprising a linear temporal order of unit operations, each including execution instructions for an addressed instrument. A set of second targets is obtained and assigned a second uncompiled workflow. Compilation of the second uncompiled workflow for each second target produces a different instance of a compiled second workflow. Each second compiled workflow comprises a linear temporal order of unit operations, with each unit operation including execution instructions for an addressed instrument and specifying a time interval.

摘要： A rotary positioning system configured to provide absolute referencing is provided. The rotary positioning system includes an encoder mounted on a motor shaft of a motor and configured to generate an index pulse corresponding to a complete rotation of the motor shaft. The rotary positioning system also includes a speed reducer coupled to the motor shaft and configured to reduce a rotary motion of the motor by a pre-defined ratio and an output drive shaft coupled to the speed reducer and configured to transfer the reduced rotary motion to a load. The rotary positioning system further includes a sensor mounted on the output drive shaft of the speed reducer and configured to determine an absolute orientation of the output drive shaft and a controller coupled to the sensor and configured to generate a correlation function of the absolute orientation and the index pulse count.

摘要： 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).
