Disclosed is a numerical control apparatus for controlling a chopping operation of a tool used in a grinding machine and the like. A programmed instruction value calculation circuit (2) outputs an upper dead point instruction (Zu) and a lower dead point instruction (Zl), a correction value calculation circuit (3) calculates and outputs correction values (.DELTA.Zu, .DELTA.Zl), and a chopping instruction calculation circuit (4) outputs a chopping control output to a manual control circuit (6) based on these instructions and correction values to operate a servo motor. When an instruction value (Zi) is input from a manual pulse generator (5) to the chopping instruction calculation circuit (4), the chopping is effected while continuously changing the upper and lower dead points, thereby enabling an operator to easily adjust the upper and lower dead points.

A numerical control method and a system therefor can perform numerical control repeatedly in accordance with a numerical control program modified by utilization of an override function. It is judged whether or not a teaching command is inputted during execution of the numerical control program (S1). When it is judged that a feed speed or spindle speed override storage command is inputted in the teaching mode (S2, S6), an override value manually set by an override switch is written into the end of a block in execution in the numerical control program (step S10). At execution of the numerical control program on and after the next time, override operation as set manually is carried out automatically.

The method enables an axial movement, in particular in the form of a pendulum motion of a numerically controlled axis to be carried out with minimal computational expenditure of time and energy. For this purpose, the pendulum profile is subdivided into the time intervals (t.sub.n-1,t.sub.n), in which different motion processes (acceleration, no velocity or constant velocity) take place. In each system clock, it is checked in which time interval (t.sub.n-1,t.sub.n), the sum of the already output system clocks (i.sub.N T) lies, so that with the corresponding, previously determined path-time equation (S.sub.n (t)), the path segments to be output by the control are calculated and can be output to the operating mechanism of the axis. A change in the tool path feedrate by means of an override setpoint selection can be effected in the fine interpolator by multiplying the system clocks (T) by a constant factor (f).
摘要:
A sewing machine is disclosed wherein the positional coordinates for successive stitch penetrations are stored in a memory having addressable locations corresponding to a plurality of operator selectable patterns. Means are provided for operator initiation of an override command to selectively alter the operation of the feed and bight actuators to an amount of motion different from that dictated by the stored pattern information. An operator influenced control provides a digital signal corresponding to a desired alteration value. Override memory locations are provided for storing bight and feed actuator motion alteration values. These locations are addressed in accordance with the selected pattern and the digital override signal provided by the operator. The alteration values are utilized for control of the appropriate feed and bight actuators.
