    • More accurate digitizing data are obtained in a profile control system for profile measurement of a shape of a surface of a model. When a tracer head (1) profiles a surface of the model (2), position detecting means (3) detects a position of the tracer head (1), and when displacement detecting means (4) detects a displacement of a stylus (1a) provided on the tracer head (1), profile data storage means (5) stores detected positions and displacements at a predetermined cycle. Positional increment calculating means (6) detects positions and displacements for respective axes of a profile plane at a predetermined cycle, and correct for an increment from a value of a position, which was detected last time, by means of a displacement to calculate the increment as a positional increment. Movement vector value calculating means (7) calculates a movement vector value in the last movement interval on the basis of the calculated positional increment, and axial movement control means (8) controls an axial movement of the tracer head (1) with the calculated movement vector value taken as a profile direction in the present movement interval.

    • A tool is made to copy a model, following the same path as that of a tracer head which copies the model, and lagging the tracer head by a predetermined time in order that a cutter doesn't bite a work at a corner part. One each axis of a machine tool, the tracer head is driven independently of the tool by sub-motors additively provided on the feed shafts for the tool. Copying command values are stored in a FIFO memory (41), and are outputted to each axis of the machine tool at predetermined time intervals. In a computing circuit (43), speed command values (Vxs) for the sub-motors are computed from the copying command values. According to these speed command values (Vxs), the tracer head copies the model, preceding the tool.

    • A profile control device for a rotating body, in which profiling is performed while rotating a model and a work. A plurality of point coordinates (P1 ∼ P10) to be determined by positions on the center axis of rotation and rotation angles of the rotating shaft are set on the outer periphery of the model (6) and profiling is performed on the basis of electric potential lines connecting a plurality of points (P1 ∼ P5, P6 ∼ P10) to each other. Hence, even when profiling of a model having a shape varying along the center axis of the rotating body, such as a groove in a cylindrical cam, is performed, the time taken for profiling can be reduced by encircling only a groove zone with the electric potential lines for defining, whereby the groove only can be profiled with high precision.

    • This invention relates to a pick feed method in rotary member profiling which rotates a model MDL), moves back and forth a stylus (ST) kept in contact with the model in a direction of the centre of rotation (O M ) of the model in accordance with the model shape, and pick-feeds the stylus within a plane parallel to the model rotation axis whenever the model rotates once, so as to make profile control During this pick-feeding, the entire periphery of the model is devided into two sections by a line (LL') connecting a point (P L ) having a predetermined rotary angle (θ L ) and the center of rotation (O M ) of the model so as to form first and second areas (Al, All). When the stylus (ST) is rotated relative to the model (MDL) by rotary member profiling control, judgement is made in which areas the stylus exists and pick-feeding is not carried out when the stylus has entered the second area (All) from the first area (Al), while pick-feeding is executed when the stylus has entered the first area from the second area.
    • 本发明涉及一种旋转构件轮廓的拾取进给方法,该方法使模型(MDL)旋转,在模型的旋转中心(OM)的方向上来回移动与模型保持接触的触针(ST) 根据模型形状,并且每当模型旋转一次时,在与模型旋转轴平行的平面内拾取手写笔,以便进行轮廓控制。 在该拾取期间,模型的整个周边通过连接具有预定旋转角度(θL)的点(PL)和模型的旋转中心(OM)的线(LL')分成两部分 以形成第一和第二区域(AI,AII)。 当通过旋转构件成形控制使得触针(ST)相对于模型(MDL)旋转时,当触笔已经进入第二区域(AII)时,判断存在触针的哪个区域并且不执行拾取进给 第一区域(AI),而当触控笔已经从第二区域进入第一区域时执行拾取。
