ABSTRACT:
A stroke end checking apparatus of a machine tool of numerical control stores an actual machine coordinates value of each of the table stroke ends on the basis of the machine reference point in detecting each of the table stroke ends which restrict a movement of the processing table in a two-dimensional direction. This apparatus also displays the relationship of the processing locus with the positions of the table stroke ends in the two-dimensional direction by the processing program of numerical control prior to actual processing on the basis of the machine corrdinates value. This enables the graphic stroke ends on the display screen to coincide with the corresponding table stroke ends, thereby permitting a rapid and accurate stroke end checking operation on the graphic display screen without the program checking operation which accompanies the transfer of the processing table in an axial direction. This apparatus also enables a highly reliable stroke end checking without allowing the processing locus of the processing table to interfere with the table stroke ends at the stage of actual processing. This arrangement can decrease working hour for preparation prior to actual processing and as a consequence improve working efficiency.
