摘要： A method of toolpath generation is provided whereby the tool may be any smooth convex axisymmetric shape. The tool includes a tool body extending between a shank and a head. The shank is configured to be mounted in a collet which may optionally rotate. In the case of a stylus tool, the head has an axisymmetric forming surface used to press metal. In the case of a routing tool, the head has cutting surfaces which are enveloped by a smooth convex axisymmetric surface and the tool is used for milling a part. In a least one embodiment the tool is a stylus tool which has a forming surface that has been generated from a portion of a clothoid curve.

摘要： Provided is a technique for converting an NC program into an NC program capable of ensuring appropriate precision in working while avoiding the occurrence of differences in levels caused by correction during the cutting of a cut surface of a workpiece. In the NC program conversion processing method to convert a conversion source NC program (1424) and generate a conversion result NC program (1425), the method includes based on a plurality of blocks in the conversion source NC program (1424), identifying a contactless portion tool path, which is a path on which a tool of a work machine executing the conversion source NC program does not come into contact with a workpiece during the processes corresponding to the blocks; identifying contactless blocks, which are the blocks having only the contactless portion tool path as a path; determining the tool route correction quantity in the tool radial direction in a work process of the workpiece according to the following blocks, which are one or more of the blocks following the contactless blocks; and creating blocks including descriptions for correcting the tool route by the tool route correction quantity, before the following blocks.

摘要： In described examples of methods and control systems to control a position and/or velocity of a machine, control circuitry is coupled to receive and dither a control signal, and to compute a control output value according to the dithered control signal and a control function. An inverter is coupled to the control circuitry, to control the position and/or velocity according to the control output value.

摘要： A motor control device comprising a motor control unit that, on the basis of an operation command signal for driving a motor and a feedback signal, from an encoder, corresponding to the operation of the motor, generates a command value pertaining to the operation of the motor in accordance with a prescribed feedback scheme so that the operation of the motor follows the operation command signal, wherein interrupt processing of a drive signal is executed by an interrupt unit on the basis of a comparison result of two items pertaining to a prescribed feedback value calculated using the feedback signal from the encoder, and to a state calculation value that is calculated on the basis of the operation command signal and that pertains to an operating state of the motor comparable with the prescribed feedback value.

摘要： A system and an apparatus capable of independently driving movers are described herein. The system and apparatus includes: a track that forms a path for movers; a plurality of movers movably mounted on the track for moving along the path; and a plurality of drive elements fixedly arranged along the track. The drive elements each have a surface that is oriented to contact a driven member of the movers. The drive elements are configured to sequentially engage the driven member of a plurality of the movers to provide controlled independent motion of the movers along the track. The drive elements may be driven by rotary motors. A method of independently driving movers is also described herein.

摘要： A control device calculates a position deviation between a position of a movable member designated by a position command and a measured position of the movable member by a position detector at each sampling period, adds a disturbance signal generated from a phase signal having a predetermined period to a drive signal generated from the position deviation to which an amount of correction is added, causes a motor for driving the movable member to operate based on the drive signal to which the disturbance signal is added, calculates the amount of correction by using a dynamic characteristic compensation filter in such a way as to reduce the position deviation, and changes a configuration of the dynamic characteristic compensation filter in such a way that an evaluation value related to magnitude of the position deviation satisfies a predetermined condition.

摘要： A machine tool includes three mutually independent data transmission mechanisms. The data transmission mechanisms include respective transmission units which assign codes for detecting errors to data acquired from the output of sensors, and which transmit the data. A machine controller includes an operation judgment unit which judges whether operation of a feed axis motor is continued. The operation judgment unit judges that operation is continued when there are two pieces of data for which a relationship between the data and the code matches a rule, and the two pieces of data are within a predetermined judgment range. The operation judgment unit judges that the feed axis motor is stopped when at least one of the pieces of data for which the relationship matches the rule deviates from the judgment range.
