Abstract

The invention discloses a cycloidal milling rough machining method for engine casing parts, which comprises the following steps: step 1, performing regional division on the casing parts to be processed according to the boss features; Line milling to open the lower slit; step 3, perform trochoidal milling on the area where the lower slit has been opened; step 4, perform trochoidal milling on the remaining unprocessed area around the boss. In the rough machining of the casing, the method of the present invention adopts the trochoidal milling method to remove the material surplus as much as possible, avoids the large meshing angle of the slot milling and side milling in the closed area, improves the heat dissipation conditions of the tool at the same time, and can reduce the cutting tool to the greatest extent. The wear speed is improved, and the processing efficiency of casing parts is improved.

Description

technical field [0001] The invention belongs to the field of machining, and in particular relates to a cycloidal milling rough machining method for engine case parts. Background technique [0002] The traditional rough milling of the outer surface of the casing adopts the side milling method for the semi-closed area. In order to ensure higher processing efficiency, a large radial depth of cut and a small feed processing strategy are adopted. This processing method As a result, the angle between the tool and the workpiece is large, and the mechanical load received by the tool is large. At the same time, the large meshing area leads to poor heat dissipation and aggravates the wear of the tool. For the closed area, the lower slit is first processed by slot milling, and after the lower slit is opened, it is processed by side milling. During the slot milling process, the tool wrap angle reaches 180 degrees, the tool load is large, the heat dissipation performance is not good, an...
