    • 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.
    • 按照与复制模型的示踪器头的路径相同的路径,并且将示踪器头滞后预定时间,以便切割器不在拐角部分咬合工件,来复制模型。 机床的每个轴线上,示踪器头部通过辅助设置在工具的进给轴上的子马达独立于工具驱动。 复制命令值存储在FIFO存储器(41)中,并以预定的时间间隔输出到机床的各个轴。 在计算电路(43)中,根据复制命令值计算子电动机的速度指令值(Vxs)。 根据这些速度指令值(Vxs),示踪器头复制模型,在该工具之前。

    • @ A method which makes it possible to speedily and reliably input parameters concerning the direction of a profiling feed shaft, a pick-feed method, and the direction of an approach shaft, etc. Identification symbols identifying a plurality of profiling parameters are displayed on a displayed device. When an operator positions a cursor at the portion of the display device where a certain identification symbol is displayed and then presses a parameter input request key, a series of parameter format data corresponding to the identification symbol is displayed on a blank portion of the display device. When the operator presses one of the format data selection keys arranged so as to correspond to the displayed format data, one format data item corresponding to the selected key is stored in a data memory as a profiling parameter value and, at the same time, is displayed on the displayed device so that it can be verified by the operator.

    • Improvement in machining accuracy and operational performance of a system of tracer control according to the signal from a tracer head. The system includes an input means (KB) for entering position information designating a given position on a model and a detecting means (PCX, PCY, PCZ) for detecting the position of a tracer head. During tracing machining, the differences between the work dimensions and the model dimensions are obtained on the basis of the position information and the detected results of the detecting means (PCX, PCY, PCZ), and then, after finishing the tracing operation, the machining conditions relating to the amount of cutting are changed so that the differences become zero and the tracing operation is executed again.
