    摘要： A tool presetter and a tool offset amount calculation method are provided which ensure easy and accurate determination of reference tool offset amounts in a machine tool having a pivotal tool spindle stock. The tool presetter is mounted in a composite lathe having a pivotal tool spindle stock 17. The tool presetter calculates tool offset amounts Oz (=A−Zm), Ox (=B−Xm) on the basis of machine coordinate values Zm, Xm of the tool spindle stock detected when a nose of a tool T is in contact with Z-axis and X-axis detection points of a presetter sensor 18 with the tool spindle stock 17 pivoted by a pivot angle &agr;, and machine coordinate values A, B of the Z-axis and X-axis detection points of the presetter sensor 18, and calculates reference tool offset amounts Lz, Lx from predetermined expressions on the basis of the tool offset amounts Ox, Oz and the pivot angle &agr; of the tool spindle stock 17.

    摘要： A method for synchronously interlocking feed axes of a lathe is disclosed. In particular, a numerical controller (NC) controls the operation of a lathe by sending position command signals to servo amplifiers. The lathe turns a long workpiece chucked by two opposed headstocks which are driven synchronously. The servo amplifiers send signals to corresponding directional servo motors for moving the headstocks in respective directions. The present invention overcomes the problems of mechanical and workpiece displacement developed as loads on the servo motors by compensating for the positions of the feed axes by means of position offset values determined from the displacement of the machine or workpiece. Specifically, the displacements are detected in accordance with a difference between the torque of the two feed axes to be controlled for synchronous interlocking. In this manner, the displacement of the machine or workpiece is compensated for by moving the headstocks, which are synchronized in the corrected positions.

    摘要： A machine control apparatus has several machine members whose positions are to be controlled and has several servomechanism loops for controlling the members. Each servomechanism loop includes a controller, and switching is provided by which the inputs and outputs of the various controllers can be switched to control different ones of the movable machine members. Each controller has a data storage register for storing the instantaneous value of error signal of its servomechanism loop. Upon changeover of a particular member from one controller to another, the error signal data in the storage register of the outgoing controller is transferred to the error storage register of the incoming controller, so that the error signal data remains associated with the member being controlled, and no inaccuracies are introduced into the position of the controlled member.

    摘要： The present invention provide a workpiece exchanging system in a CNC lathe having two spindle heads. The workpiece is machined by a spindle head A (S1, S2), a spindle head B is moved toward the spindle head A while loading a servo motor controlling a feed axis for the spindle head B to a torque limit (S3, S4). An error (d) of the feed axis is detected when this movement is completed, and it is determined whether the workpiece is normally clamped by a chuck mounted at a spindle head (S5, S7). The workpiece is machined as it is in accordance with the error of the feed axis (S9), is machined after being moved by a coordinate corresponding to the error (S8), an alarm is displayed, and the CNC is stopped (S10).
