Problems solved by technology

When using a ball end milling cutter to cut the concave surface of a hardened steel mold, the cutting impact caused by the change of the curvature of the processing surface makes the vibration of the milling cutter changeable, and the cutting contact relationship between the tool and the processing surface is in an unstable state, resulting in the deterioration of the surface morphology. Low precision, reduced service life and cutting efficiency of milling cutter
[0003] There are two existing testing methods for high-speed milling of hardened steel concave surface milling cutter vibration and machined surface morphology: (1) The milling cutter vibration test is performed directly on a large hardened steel mold, which can easily cause mold surface damage and affect Die life; (2) The cutting experiment w

Abstract

The invention relates to a high-speed milling process experiment method and a test piece, in particular to a high-speed milling process experiment method for an integrated quenched steel concave surface test piece and the concave surface test piece. The high-speed milling process experiment method and the concave surface test piece are used for solving the problem that existing process data and design methods can not meet the requirement for efficiently machining quenched steel moulds. According to the high-speed milling process experiment method, the integrated quenched steel concave surface test piece with a variable-curvature upper surface is designed and machined, three tool cutting paths in different directions are made along the test piece through bulb milling tools, the experiment of cutting the upper surface of the integrated quenched steel concave surface test piece is conducted, the data of milling tool vibration amplitude and machined surface scallop height in the feeding direction of the milling tool and the milling width direction are acquired, the influence on the vibration of the milling tool and the shape of the machined surface from curvature changing of the quenched steel concave surface is tested, and a high-speed milling process scheme for the integrated quenched steel concave surface is given. The test piece is of an integrated cuboid structure and is composed of a bottom boss and a middle area to be cut. The high-speed milling process experiment method and the concave surface test piece meet the requirement for efficiently machining the quenched steel moulds.

Description

technical field [0001] The invention relates to a high-speed milling process experimental method for a concave curved test piece, in particular to an integral hardened steel concave curved test piece high-speed milling process experimental method and a concave curved test piece, belonging to the technical field of complex surface processing. Background technique [0002] Large-scale hardened steel molds are produced in one piece, with complex profiles, and the curvature distribution of the high-hardness machined surface is changeable. When using a ball end milling cutter to cut the concave surface of a hardened steel mold, the cutting impact caused by the change of the curvature of the processing surface makes the vibration of the milling cutter changeable, and the cutting contact relationship between the tool and the processing surface is in an unstable state, resulting in the deterioration of the surface morphology. The precision is low, and the service life and cutting ef...
