Abstract

The invention provides a spur gear numerical control machining method. The spur gear numerical control machining method comprises the following steps that step S01, a workpiece is clamped; step S02, the workpiece is rotated; step S03, shape machining is performed; step S04, C-axis indexing positioning is performed; step S05, tooth profile machining is performed; step S06, C-axis indexing positioning is performed to a next tooth part; step S07, the step S05 and the step S06 are repeated; step S08, cutting and blanking are performed; and step S09, burrs and sharp edges of finished products are removed. The workpiece product manufactured by the spur gear numerical control machining method can eliminate the precision error problem caused by the secondary positioning clamping during the spur gear tooth profile machining, the workpiece product is machined on a CNC machine tool from the machining to the finished product blanking, midway discharging is not needed for secondary clamping machining, and the machining accuracy of the gear is ensured.

Description

technical field [0001] The invention relates to a machining method, in particular to a numerically controlled machining method for spur gears. Background technique [0002] CNC machine tool is the abbreviation of numerical control machine tool. It is an automatic machine tool equipped with a program control system. It is one of the most widely used CNC machine tools at present. The control system can logically process programs with control codes or other symbolic instructions, decode them, express them in coded numbers, and input them into the numerical control device through the information carrier. After calculation and processing, various control signals are sent by the numerical control device to control the movement of the machine tool, and the parts are automatically processed according to the shape and size required by the drawing. CNC machine tools solve complex, precise, small-batch, and multi-variety parts processing problems. It is a flexible, high-efficiency aut...
