    • There is disclosed a method of controlling, and a control system for, an apparatus, such as a machine tool (100), for forming a straight configured contour, or a straight configured segment forming part of a curvilinear contour, and having co-ordinates in at least two directions (X, Y and Z), said apparatus incorporating a work piece support (102), a contour forming means, such as a milling cutter (107), incremental drives (M.sub.X, M.sub.Y and M.sub.Z) to effect relative movement between said support (102) and said milling cutter (107) in said directions, and involving determining the components of said contour or segment in said directions (X, Y and Z) as a number of increments of length equal to a predetermined distance, providing a continuous feed of input pulses in a computer (S B C), continuously counting in the S B C, in respect of each said direction, a predetermined number of input pulses in the ratio of the inverses of said number of increments, and subsequently feeding via motor control (MCB) and motor drive (MDB) boards,(i) a drive pulse to one of said incremental drives (M.sub.X, M.sub.Y or M.sub.Z) to effect movement in one of said direct directions (X, Y or Z) over said predetermined distance each time the predetermined number of input pulses relevant to that direction have been counted, and(ii) a drive pulse to at least one other of said incremental drives (M.sub.X, M.sub.Y or M.sub.Z) to effect movement in one other of said directions (X, Y or Z) over the same predetermined distance each time the predetermined number of input pulses relevant to that direction have been counted,whereby said movements combine to form a relative movement between said support (102) and said milling cutter (107) such as to produce said contour or said segment.
    • 公开了一种用于形成直线构造轮廓的装置,例如机床(100)的控制和控制系统的方法,或形成曲线轮廓的一部分的直线构造段,并且具有坐标 在至少两个方向(X,Y和Z)上,所述装置包括工件支撑件(102),轮廓形成装置,例如铣刀(107),增量驱动器(MX,MY和MZ) 在所述方向上在所述支撑件(102)和所述铣刀(107)之间的运动,并且涉及将所述方向(X,Y和Z)上的所述轮廓或段的分量确定为等于预定距离的长度增量 在计算机(SBC)中连续馈送输入脉冲,在SBC中相对于每个所述方向连续计数预定数量的输入脉冲,其中所述增量数量的反转比例,以及随后的通过 电机控制(M CB)和马达驱动器(MDB)板,(i)到所述增量驱动器(MX,MY或MZ)之一的驱动脉冲,以在所述直接方向(X,Y或Z)中的一个上移动所述预定距离 已经计数与该方向相关的预定数量的输入脉冲,并且(ii)到所述增量驱动器(MX,MY或MZ)中的至少另一个的驱动脉冲,以实现所述方向(X, Y或Z),每当与该方向相关的预定数量的输入脉冲被计数时,相同的预定距离,由此所述运动组合以形成所述支撑件(102)和所述铣刀(107)之间的相对运动, 产生所述轮廓或所述段。
