    摘要: A robot control method capable of eliminating any influence of motion in a preceding path section to assure an accurate path movement with respect to a portion of a path section toward an end point. In a motion statement, a path-assurance section is previously designated in terms of length, time or path-assurance ratio for a moving path �2!.fwdarw.�3!. A path motion plan EFGH for the moving path �2!.fwdarw.�3! is created so that a path section represented by DHGK is the path-assurance section designated in the motion statement, assuming that D represents a terminal point of the motion along the moving path �1!.fwdarw.�2!. Consequently, an influence of motion of the moving path �1!.fwdarw.�2! is not exerted on the motion after a point in time represented by D or K, to assure a movement on the path �2!.fwdarw.�3! in the path-assurance section.

    摘要: Based on an offset direction which indicates whether a laser beam (RB) is offset in a direction to the right side or left side of a travelling direction contained in a motion definition statement, and the direction of a curve at a corner portion (CN) of a laser beam path (b.sub.i,b.sub.i+1), it is determined whether an inner side or outer side of the beam path at the corner is a part (PT). If the inner side of the corner is a part, an NC part program for laser machining is created upon inserting a preset escape path (EP) in the corner portion of the beam path. If the outer side of the corner is a part, an NC part program for laser machining is created in such a manner that similarly set machining conditions prevail in preset machining condition modification intervals.

    摘要: The tolerable maximum feed rate Fd is calculated in real time during operation based on the tolerable minimum moving time Ta to be determined by the data interpretation and the moving distance L of each machining block. If the command feed rate Fc exceeds the tolerable maximum feed rate Fd, the actual feed rate for the block is set to the tolerable maximum feed rate Fd, thereby realizing smooth deceleration and preventing mechanical shock of the machine tool and reduction in machining accuracy. Required time for each processing element is determined in advance, the sum of processing times corresponding each element is calculated by judging the processing mode element contained in machining for each block. Then, the feed rate is controlled by determining the tolerable minimum moving time for each block based on the calculated sum of processing times.

    摘要: A method of moving a cutter blade along a contour defined by a plurality of segments each connected end to end with one another and having at least one angle disposed between consecutively ordered segments calculates a distance from a corner point along one and another line segments and fits an arc to be followed by the blade between the line segments for eliminating repeated high force short time system inputs and replacing them with lower force longer duration inputs to affect the reduction and mechanical wear and the reduction of shocks to the system. The method further includes a process by which individual velocity profiles are determined for each contour in order to run the system at maximum velocity at all times during the course of a cutting operation.

    摘要: An apparatus for forming a line of separation in a plastic work surface includes a tool having a tool holder of thermally conductive material, an electric heating element and a tool member having a separating point. The holder is surrounded by an insulating member and includes a sleeve portion in which the tool member is releasably secured, the tool member projecting from the body in freely exposed manner with the separating point remote from the holder whereby the work surface may be engaged solely by the separating point which comprises a tip from which a surrounding surface extends in divergent manner. The holder is arranged to conduct heat from the heating element to the tip and suitable control means are provided for regulating the heating element temperature to a desired value. The apparatus is adapted to traverse the tool in orthogonal directions across a work-support surface in a head movably mounted above the surface, the tool being releasably mounted in a clamping arm of a pivotable lever having an actuating arm, actuating means engaging the actuator arm to bring the separating point of the tool into and out of engagement with the work on work-supporting surface by pivotal movement of the lever.Since the separating point is freely exposed the depth of penetration into the work is not effected adversely by surface irregularities or cutting swarf on the work but is determined by the point form, temperature rate of movement and pressure on the work.
