摘要： An accleration/deceleration controller is used for a numerical controller in which a machining program is given from an instruction tape (3) to a machine tool and is decoded to simultaneously control movements of a plurality of axles. In order to keep the continuity in the machining locus between program blocks, a comparator circuit (7) compares the actual speed of the object during the deceleration with the required speed in the next instruction data block, and inhibits a pulse distribution circuit (6) from performing the pulse distribution for the next instruction data block until the two speeds are in agreement with each other, so that the tool positioning can be effected more accurately by servo motors (1) and (2) which are accelerated and decelerated in accordance with interpolated data.

摘要： First and second tool control blocks precede and follow a corner on a tool path, respectively, and perpendicularly intersect each other at the corner. A pulse distribution computation based on NC command data in the second block is not executed at the instant that a pulse distribution computation based on NC command data in the first block ends. Rather, a pulse distribution computation based on the NC command data in the second block is performed starting at the instant that a feed speed based on the NC command data in the first block attains a prescribed speed by being decelerated. As a result, the torch of a gas cutting machine or the like will cut the corner portion quickly to a high degree of accuracy, without cutting the corner to an overly rounded shape.

摘要： Tracer control apparatus, for a tracer machining system, has a memory storing position A, along the PICKFEED AXIS, of the first clamping feed in initial tracing of a clamping feed area H1 and position B at which clamping feed is absent after initial tracing of area H1.
Using the stored positions the apparatus causes repeat tracings back and forth between A and B.
Clamping level setting means 11 to 15 set an initial clamping level LCZ for clamping feeds in initial tracing of area H1, and add increments inc to that level for successive repeat tracings.
Only when the incremented clamping level is not reached in a repeat tracing, or the incremented level reaches a limit value, does tracing proceed beyond area H1. The clamping level is set back to its initial value.
A method of machining is provided in which repeat tracing is carried out only in areas where required, e.g. H1, in dependence upon stored positions A and B and incrementing clamping levels.

摘要： During a tracing operation of a tracer head (TR) the present position of the tracer head in the Z-axis direction is detected and a maximum value (Zma) of the detected tracer head positions is stored in a memory means (AR). When the tracer head (TR) is returned from a trace terminating end (LX2) to a trace starting end (LX1), it is quickly returned to a position (Zma + a) corresponding to the sum of the stored maximum value (Zma) and a constant value (a).

摘要： In one forward or backward trace path on a model (MDL), a jerk inatracer control system point (P 1 to P 4 ) in the surface configuration of the model (MDL) is detected and the position of the jerk point is stored in a memory (MEM). The reduction of the trace velocity is started a predetermined distance (a) short of the stored position of the jerk point (P 1 to P 4 ) in the trace direction and when a jerk point is detected again, the position of the jerk point previously stored in the memory (MEM) is updated and the reduction of the trace velocity is released, thus achieving high accuracy trace.

摘要： Tracer control apparatus, for a tracer machining system, has a memory storing position A, along the PICKFEED AXIS, of the first clamping feed in initial tracing of a clamping feed area H1 and position B at which clamping feed is absent after initial tracing of area H1. Using the stored positions the apparatus causes repeat tracings back and forth between A and B. Clamping level setting means 11 to 15 set an initial clamping level LCZ for clamping feeds in initial tracing of area H1, and add increments inc to that level for successive repeat tracings. Only when the incremented clamping level is not reached in a repeat tracing, or the incremented level reaches a limit value, does tracing proceed beyond area H1. The clamping level is set back to its initial value. A method of machining is provided in which repeat tracing is carried out only in areas where required, e.g. H1, in dependence upon stored positions A and B and incrementing clamping levels.
