Abstract

Provided is a machining method of a wedge-groove gauge. The invention relates to the machining method of the wedge-groove gauge with the purpose of solving problems in the prior art such as complicated operation for measuring machining precision of a wheel disc dovetail groove and inaccurate measurement. In order to solve such problems, the method is realized by adopting following steps: firstly, discharging: selecting rectangular workblank 230 mm long, 80 mm wide and 50 mm high; secondly, rough mill and precision grinding; thirdly, milling end surfaces including a first oblique plane and a second oblique plane; fourthly, machining a circular conical surface by utilization of a numerical control milling machine; fifthly, machining a workpiece. The operation for machining the workpiece further comprises following steps of installing workblank onto a wire cutting machine and machining the bottom surface of the workpiece. Therefore, two vertical surfaces are machined between the bottom surface of the workpiece and the circular conical surface. A protrusion is machined between each one of the two vertical surfaces and the bottom of the workpiece and comprises a first protruding oblique plane and a second protruding oblique plane, by means of which each vertical surface is connected with the bottom surface of the workpiece in order. The machining method of the wedge-groove gauge is used for the machining field of wedge-groove gauges.

Description

technical field [0001] The invention relates to a processing method of a wedge groove gauge Background technique [0002] Rubrics are simple structures, usually entities of precise size and shape. Rubrics are also an authenticity assessment tool, which is a set of standards for evaluating or grading a student's test, development portfolio, or performance. At the same time, it is also an effective teaching tool and an important bridge between teaching and evaluation. The gauge is a precision measuring instrument. During the use of the gauge, it needs to be in contact with the workpiece many times. How to maintain the accuracy of the gauge and improve the reliability of the test results In the past, the wedge groove gauge was processed in one clamping process on the five-axis CNC milling. Because the wedge groove gauge workpiece is slender, the deformation after processing is relatively large, and the machining accuracy is difficult to guarantee. Contents of the invention ...
