Computer controller for grinding machine - calculates grind wheel carrier speed in accordance with predetermined matter removal per unit time when data entry rectification is made

摘要

The system uses a mini computer for controlling a grinding machine for shaping a shaft. The mini computer performs all the calculations required to obtain the correct dia. For a shaft with different dias. the reference used is specific volume to be removed in unit time. This allows the speed to be controlled and reduces programming required. Experimental data for the volume of material to be removed from a shaft with several dias. in a second is determined for the width of the grinding wheel. This value is entered manually by the operator into the computer memory. The computer calculates the speed of advance for the wheel carrier and also rotational speed of the shaft. These values are entered progressively into memory for centralling action to be effected.
