ABSTRACT:
A feed control apparatus for a numerically controlled grinding machine having a work table movable in a first axis direction, a wheel head provided thereon with a grinding wheel of the angular type and movable in a second axis direction perpendicular to the first axis, wherein the feed control apparatus comprises a memory for storing an instruction for effecting relative movement between the work table and the wheel head, and command data indicative of a movement amount of the wheel head in the second axis direction, a computer for reading out the stored instruction and command data to calculate a movement amount of the work table on a basis of the read out command data and for producing first and second output signals respectively indicative of the movement amount of the wheel head and the calculated movement amount of the work table, and a feed mechanism responsive to the output signals from the computer for effecting the relative movement between the work table and the wheel head to move the grinding wheel along a path extending at an acute angle with respect to the second axis.
