Abstract
A numerically controlled grinding machine of the present invention grinds a cylindrical surface of a workpiece by a relative movement between the workpiece and a grinding wheel. The grinding conditions such as a grinding method and a finishing diameter of the workpiece are inputted so that data necessary for grinding the Workpiece are automatically determined in dependence upon the grinding conditions. The automatically determined grinding data are displayed on a display means. The grinding data displayed on the display means are modified by one of the four rules of arithmetic. The modification are carried out in accordance with a compensation rate set by override switch and the like or a compensation value inputted by a key operation.
Claims11
A numerically controlled grinding machine for grinding a cylindrical surface of a workpiece by a relative movement between the workpiece and a grinding wheel, said numerical controlled grinding machine comprising:
- means for inputting grinding conditions;
- means for automatically determining grinding data necessary for grinding the workpiece in dependence upon the grinding conditions inputted by said input means;
- means for displaying the grinding data determined by said determination means;
- and
- means for modifying the grinding data displayed on said display means by one of the four rules of arithmetic.
A numerically controlled grinding machine for grinding a cylindrical surface of a workpiece by a relative movement between the workpiece and a grinding wheel, said numerical controlled grinding machine comprising:
- means for inputting grinding conditions;
- means for automatically determining grinding data necessary for grinding the workpiece in dependence upon the grinding conditions inputted by said input means;
- means for displaying the grinding data determined by said determination means;
- means for setting a compensation rate of the grinding data;
- means for modifying the grinding data displayed on said display means in accordance with the compensation rate set by said rate setting means.
A numerically controlled grinding machine for grinding plural step portions of a workpiece by a relative movement between the workpiece and a grinding wheel, said numerical controlled grinding machine comprising:
- means for inputting a grinding method of each step portion;
- means for inputting a finishing diameter of each step portion;
- and
- means for automatically determining data necessary for grinding each step portion in dependence upon said inputted grinding method and the finishing diameter of each step portion;
- means for displaying the grinding data for each step portion which are automatically determined by said determination means;
- and
- means for collectively modifying plural grinding data displayed on said display means by one of the four rules of arithmetic.
