    • A digitizing method which controls the movement of at least one axis (X- or Y-axis) by the numerical control based upon the passage data, which controls the movement of another axis (Z-axis) by the profile control, and which monitors the current positions of the axes in order to obtain three-dimensional data on an object. A numerical controller (101) performs numerical control based on NC data supplied from an NC tape (106) to move a tracer head (105) in the X- and Y-directions. A profile controller (102) performs the control relying upon displacement components (epsilonX, epsilonY, epsilonZ) of the axes generated by the tracer head, to produce a speed instruction VZ of the Z-axis, and to move the tracer head in the direction of Z-axis. The numerical controller (101) counts the number of pulses (FZ) generated every after a motor (MZ) that drives the profile control axis (Z-axis) has made rotation of a predetermined angle, and obtains the current position of the profile control axis. The numerical controller further obtains an instruction position of the numerical control axes (X-, Y-axes) using the passage data, and subtracts servo delay amounts (Ex, Ey) which are the contents of error registers (ERx, ERy) from the instruction position, in order to obtain a current position expressed by a mechanical position. Thereafter, the current positions of the axes represented by mechanical positions are stored in a memory (101b) every after a predetermined period of time.

    • PURPOSE: To simplify constitution, and facilitate addition and changing of functions by constituting circuits through proper combination of software and hardware by the use of a microcomputer.
      CONSTITUTION: A central processing unit 1 successively reads out the programs or data written into an ROM2 and makes data operation while executing prescribed sequence processing thereby performing necessary input and output controlling. External devices are a pulse motor driver part, a detecting part, an operating part, etc. The unit 1 supplies gate opening and closing signals, acceleration and deceleration signals and forward and backward revolving signals as control signals to the external devices in accordance with the input signals from the external devices. The programs or data in the ROM2 are easily rewritable. Hence, the constitution is simplified and the addition and changing of functions are made easy with this constitution.
