摘要： A position control system, capable of correcting the positional deviation between mechanically related control axes. The position control system comprises a structural body having a Y-shaft supported by a fixed member so that two end portions can move in a vertical direction and a main shaft provided in this shaft so that it can move in a horizontal direction, servo motors for driving the two end portions, a servo motor for driving the main shaft, and a control device for performing the servo control of the servo motors. The control device adjusts the positions of the two end portions of the Y-shaft in accordance with the position of the main shaft with respect to the Y-shaft at the position control to correct the positional deviation from the target position of the main shaft in the vertical direction.

摘要： A rotation axis of a work spindle and a rotation axis of a spindle primary-axis portion are rotated relative to each other and feeding of a work-piece to a tool is accordingly adjusted, whereby warpage of the tool in accordance with a change in machining condition is corrected. A revolution volume of the relative rotation is compared and calculated in process based on data entered in advance, a result of measurement by a displacement sensor and information such as a machining position, and controlled in real time until the end of machining. The relative rotation is driven by an actuator such as a piezoelectric element, at a resolution even as fine as in seconds. The data entered in advance can be sequentially updated in accordance with monitoring of a processed product.

摘要： A machine tool that attaches and detaches workpieces to and from a spindle in a shorter time includes: a machining mechanism part including a spindle, a tool rest, a first-axis feed mechanism moving the spindle in a a first axis extending along a center axis of the spindle, and a second-axis feed mechanism relatively moving the spindle and the tool rest in a second axis orthogonal to the first axis; a loading mechanism part including holding parts for holding a workpiece, and a third-axis feed mechanism moving the holding parts in a third axis orthogonal to the first axis to position them at the transfer position; and a numerical controller. The numerical controller operates to move the spindle toward the transfer position and to position the holding parts at the transfer position such that the operations at least partially overlap.

摘要： The invention relates to improvements in the multiple spindle rotary indexing machine tool systems of the prior art. Traditionally, such machine tool systems include a base and an upstanding vertical column which houses a plurality of machining stations each equipped with two-axis tool slides. In addition, the base supports a rotatable worktable, which carries a number of work-holding spindles. As the worktable rotates, these spindles are indexed through successive machining stations where a variety of operations are performed. In accordance with the invention, a spindle position measurement unit is provided to dynamically measure the exact location of each spindle indexed to position at a modified machining station. A computerized numerical control system calculates spindle position errors based on the position information provided by the measurement unit and offsets tool slide position commands to compensate for those errors. As a result, the control unit compensates for both fixed and variable spindle position variations, thus improving the machining tolerances of the machine tool apparatus. In accordance with another aspect of the invention, a high accuracy finishing station is provided which includes spindle position variation measurement and compensation in combination with an independent X and Y axis tool slide positioning system. The tool slide positioning system is responsive to CNC commands for speed control and position offset due to spindle errors.
