PURPOSE: To provide a numerical control device wherein a tool can be moved at an arbitrary angle and speed by a manual feed, in the numerical control device.

CONSTITUTION: A device is constituted of an angle setting means 1 capable of arbitrarily setting a direction of moving a tool, moving ratio calculating means 2 for calculating moving ratio in X, Y-axis directions of the tool from an angle 9 set by this angle setting means 1, feed speed calculating means 4 for obtaining a synthetic feed speed F by counting a number of pulses from a manual pulse generating means 3 and a moving command generating means 5 for obtaining a moving amount in the X, Y-axis directions from a result of calculation of the moving ratio calculating means 2 and the feed speed calculating means 4.
