Description
Technical Field
The invention relates to a rapid milling cutter for a single-side angle groove-shaped workpiece, and belongs to the technical field of mechanical processing of artillery parts.
Background
A certain part of an artillery product is provided with a special groove-shaped structure which is symmetrical up and down and has an angle on one surface, and the requirements on the dimensional precision and the surface roughness of the groove are high.
The conventional machining method of the groove adopts linear cutting machining, but the linear cutting machining efficiency is low, the straightness of the machined groove is poor, and the radian (concave center) appears in the middle of the dimension 600, so that the dimensional accuracy of the groove cannot be guaranteed. The reasons for the analysis are two: firstly, the flexibility of the molybdenum wire and secondly, the thickness dimension of the workpiece exceeds the range, and the wire cutting is not suitable for processing the workpiece with the thickness of more than 300 and high precision requirement; in addition, the surface roughness of the groove after wire cutting processing is not satisfactory.
The milling of the groove on the machining center is an effective method for ensuring the dimensional accuracy and improving the efficiency. However, at present, the national standard of China does not have a milling cutter for processing the groove with the special shape. How to design and manufacture a reasonable milling cutter for a single-sided angled groove-shaped workpiece to achieve high-quality, high-efficiency and rapid milling is the key of milling of the groove.
