Abstract

The invention relates to the technical field of key slot machining and provides a machining method for slotting of key slots by a numerical control apparatus. The machining method for efficient slotting of key slots by a numerical control apparatus is characterized in that a numerical control milling center replaces a traditional manual slotting apparatus and the slotting machining of a plurality of key slots is performed by using the indexing function of the numerical control apparatus with one-time clamping; the problems of poor machining precision, low machining efficiency and high workload of the manual slotting apparatus are solved.
