    摘要: A numerical controller is capable of foreseeing the occurrence of interference during operation of a machine and securely preventing the interference. An advanced position calculating section determines advanced time for the next interference check, based on an end time point of an interference check by an interference checking device and the sum of a time required for the interference check, a time required for communication, a time required for decelerating and stopping a movable part, and a predetermined float. If an interference checking device detects interference, the interference checking device delivers an axis stop signal the movable part.

    摘要: When a servomotor (control axis) is coasting and rotating in a servo-off state in which no current is applied to the servomotor, this servo-off state is switched over to a servo-on state in which current is applied to the servomotor, and a position control and a speed control are started. An actual speed in servo-on state is obtained in speed obtaining means by a position/speed detector. Position command means obtains a command movement amount using the actual speed as an initial speed. A position deviation amount corresponding to the actual speed is calculated, a command movement amount, a position deviation amount, and a position deviation amount remaining in a position deviation counter in servo-on state with the sign thereof reversed are added to each other as a command amount to the position deviation counter.

    摘要: The present invention relates to an area cutting method for cutting the interior of an area (AR) by moving a tool along a plurality of offset paths (CPT1, CPT2, . . . CPTn) successively offset in an inward direction from a closed curve (OLC) specifying the area (AR). In accordance with the area cutting method, the centroid (W) of the area is found and a check is performed as to whether the centroid lies inside the area. It is also checked whether line segments (L1, L2, L3, . . . ) connecting the centroid with the apices (P1, P2, . . . , P10) of the area intersect the closed curve (OLC'). If the centroid (W) lies within the area and none of the line segments intersect the closed curve, the area is not divided into a plurality of convex polygons even if the area is a concave polygon. Instead, each line segment is partitioned into a predetermined number of partitions and cutting is performed by moving the tool along a plurality of closed paths (CPT1-CPTn) connecting consecutive partitioning points Pi1 through Pi10 (i=a, b, . . . n) of the line segments.

    摘要: A machining load monitoring system to monitor a machining condition by comparing sampled data of a machining load in a trial cutting process and measured data thereof in an actual cutting process with each other precisely with respect to time. An NC command executing unit (1) executes NC commands, and updates a block number and an execution mode in an executed state table (2) when the execution of NC commands of one block is finished. A load monitoring unit (4) compares sampled data, stored in a sampled data table (3), of a machining load in a trial cutting process with measured data thereof in an actual cutting process at given intervals of time. When the block number in the executed state table (2) is updated, sampled data of a new block number are read from the sampled data table (3). The sampled data in the trial cutting process and the measured data in the actual cutting process are compared with each other at predetermined times, and an alarm is issued when the difference between the compared data reaches or exceeds a predetermined level.
