Title:
FEEDING SPEED CONTROL METHOD FOR NUMERAL CONTROL
Document Type and Number:
Japanese Patent JPH0272414
Kind Code:
A
Abstract:
PURPOSE:To omit the need to decide working speed via a program by obtaining the maximum feeding speed within a due range and slowing the speed down to the obtained level when the speed change of each axis exceeds the maximum level at a corner. CONSTITUTION:A numeral control part 101 performs a speed control process and decides feeding speed at a corner. In other words, the working speed is not designated by an NC working program 100 and defined as the maximum cutting speed FMAX set previously. Then the working speed is slowed down to a prescribed level from the level FMAX for execution of the working so that the speed change of each axis is kept under the maximum allowable speed change of each axis set previously. Thus it is not required for the program 100 to decide the working speed and at the same time the least deceleration is required. As a result, the maximum capability of a machine is ensured so that the working is performed with high efficiency and high accuracy.
