TL;DR: In this article, the authors present a numerical control gear shaping machine, where a stand column base is slidingly arranged on two longitudinal slide rails, which are arranged on the upper surface of the machine body side by side.
Abstract: The invention belongs to the technical field of gear shaping machines, in particular to a numerical control gear shaping machine. The numerical control gear shaping machine comprises a machine body; astand column base is slidingly arranged on two longitudinal slide rails, which are arranged on the upper surface of the machine body side by side; two vertical slide rails are arranged on stand columns, arranged on the stand column base, side by side; a carriage is slidingly arranged on the vertical slide rails; a rotating plate is rotationally arranged on the carriage; a cutter shaft box is slidingly arranged on a chute vertically formed in the rotating plate; a cutter is arranged on a cutter shaft of the cutter shaft box; a workpiece mounting base is arranged on the machine body positionedon the lower side of the cutter; and actions of the stand column base, the carriage, the rotating plate and the cutter shaft box are all controlled by a numerical control system. The numerical controlgear shaping machine has the advantages of greatly improving the gear machining efficiency and improving the gear machining precision.

TL;DR: In this article, a high-efficiency dry cutting gear shaping using the pinion cutter 5 that uses high-speed tool steel is achieved, at a cutting speed of 400 m/min or less without use of cutting fluid.
Abstract: PROBLEM TO BE SOLVED: To provide a gear shaping method whereby a gear can be cut at low cost through dry cutting at high speed. SOLUTION: At least one film composed basically of AlOx (1.0<=x<=1.5) is subjected to dry cutting whereby it is cut by a pinion cutter 5 coated at least on its flank, at a cutting speed of 400 m/min or less without use of cutting fluid, to create a tooth profile. High-efficiency dry cutting gear shaping using the pinion cutter 5 that uses high-speed tool steel is achieved.
