Abstract: A feed apparatus has a ball screw, a nut, a drive motor, a braking mechanism and a controller and moves a movable body vertically. When recognizing a movement command for rapid traverse relating to the movable body, the controller, when the movable body is to be moved upward, moves the movable body past a target position according to the movement command and then reverses the moving direction thereof and moves the movable body to the target position and stops it there, and, when the movable body is to be moved downward, moves the movable body directly to the target position and stops it there. After moving the movable body to the target position and stopping it there, the controller causes the drive motor to keep the position of the movable body at the stop position and causes the braking mechanism to brake the movement of the movable body.

Abstract: Relative movement in X, Y and Z axis directions is made between a main spindle and a table 6 for application in a machine tool in which a work is machined. An emitting element 12 for irradiating laser beam 11 and a photosensitive element 13 are disposed on the table 6. A measuring tool 8 with its top end being shaped as a cone form is attached to the main spindle 4. The laser beam 11 is interrupted with the cone form portion 15 of the measuring tool 8 through relative movement between the table 6 and measuring tool 8 before and after machining a work. Detection signal of interruption is generated at the moment of interruption, position is detected, operation processing is performed so that difference in X, Y and Z axes before and after machining is obtained along with values for correction. Positional coordinate values for three axis directions are detected simultaneously with a measuring device of a simple constitution by use of laser beam and values for correction such as of thermal displacement is obtained by operation processing of displacement values.

Abstract: The invention concerns a feed system control method and apparatus that can calculate an accurate backlash amount and can accomplish highly precise position control. Position errors are calculated before and after a reversal in direction of movement of a slide 30, each from the difference between the position data of the slide 30 detected by a linear scale 25 and the position data of the slide 30 calculated from the rotational position data of the servo motor 23 detected by a rotary encoder 24. The backlash amount of the slide 30 is calculated from the difference between the position error before the reversal and the position error after the reversal thus calculated. Thereafter, when reversing the direction of movement of the slide 30, the feed speed during direction reversal is increased in accordance with the backlash amount.

Abstract: A rotary electric machine comprising a stator and a rotor arranged opposedly of the stator. A magnet is provided on the stator or a frame for holding the stator at a position so as to be constantly opposed during rotation to a portion of the magnetic body of the rotor. The magnet is disposed at a position other than at a portion at which the magnetic action for rotation of the rotor occurs. The rotor is therefore constantly biased so that rotor play is minimized and non-repeatable deflections of the spindle are eliminated.

Abstract: A machine tool controlled to restart automatic operation for machining a workpiece from an interrupted point after the machine tool, which has been automatically operated by NC program commands, is caused to interrupt the automatic operation. The NC program commands are classified into a plurality of main groups with respect to the contents of motions for changing the machine state of the machine tool. When the automatic operation of the machine tool restarts after the automatic operation has been interrupted halfway, an order of execution of the NC program commands is determined such that the main groups are arranged in a prescribed order of execution, for automatically generating a machine state restoration command. The automatic operation of the machine tool can restart from the interrupted point without the need for the operator to manually generate or correct a command for restoring the machine tool to its machine.

Abstract: A machining simulation is performed on a graphic data basis prior to machining. Machining simulation means (17) simulates a forced-vibration frequency and/or a load variation frequency occurring due to interrupted cutting on the basis of machining information, and numerical control command generating means (18) generates a numerical control command on the basis of the frequencies obtained from the machining simulation means (17). A spindle rotation speed can be reflected on the actual machining and the generation of a machining program under conditions optimum for the actual machining. Therefore, the interrupted-cutting forced-vibration frequency and/or load variation frequency, or harmonic frequencies thereof which are integral multiples thereof are prevented from being close to the natural frequency of a machine, a tool, a jig or a workpiece. Thus, chattering due to resonance can be prevented, thereby improving a surface accuracy.

Abstract: A CNC tapping machine includes a spindle to which a tap is attached and a spindle motor for rotating the spindle. The load torque acting on the spindle motor that is detected when performing a tapping procedure without a workpiece is stored in a memory as referential, torque data. During a tapping procedure, a detection device detects the load torque acting on the spindle motor. A computer computes the difference between the load torque defected by the detection device and the referential load torque and uses the difference as the cutting load acting on the tap. As a result, the cutting load torque acting on the tap is accurately detected.
