Problems solved by technology

[0004] However, for parts that require a large R value of the cam fillet and high machining accuracy, due to the large fillet and high precision requirements, the processing plan has a certain uniqueness and originality, and there is no mature reference for it. scheme, which makes it more difficult to process, and the R value of the fillet cannot be effectively guaranteed
If the blade nose radius is used to make the corresponding radius value, the cutting resistance will increase sharply during machining due to the excessively large radius of the knife nose arc, which will lead to faster wear of the blade, and will directly cause the phenomenon of knife beating, resulting in the processing of tools and processed products. scrap parts
[0005] Therefore, for the milling method of the large cam fillet of the engine camshaft, the original optimal design method has certain limitations

Embodiment Construction

[0021] It should be noted that the embodiments of the present invention and the features of the embodiments may be combined with each other under the condition of no conflict.

[0022] The present invention will be described in detail below with reference to the accompanying drawings and in conjunction with the embodiments.

[0023] Optimal design calculation is a design method that selects the best scheme from a variety of schemes and calculates it. It is based on the optimization theory in mathematics and uses the computer as a means to establish an objective function according to the performance goals pursued by the design, and seek the optimal design scheme under the given constraints. The invention mainly aims at the optimization design calculation of the camshaft cam fillet milling processing.

[0024] Ordinary cam fillet size requirements are R1-R3, and the machining fillet is small. The conventional cam fillet milling optimization design calculation can basically ensu...

Abstract

The invention provides an optimization design method for cam fillet milling of a camshaft, which uses an alloy end mill with a certain radius of the cutter blade to carry out milling processing, and adopts a layer-by-layer circular arc progressive method; calculates the contact area between the cutter and the processing arc, and adjusts the Contact area, control cam fillet; conduct trial production, and feedback the results, and choose the optimal solution. The invention reduces the limitation of the optimization design of the large fillet cam fillet of the engine camshaft, improves the maturity of the processing method, ensures the first-time success of the process method design, and thus improves the effectiveness of the optimization design calculation.

Description

technical field [0001] The invention belongs to the field of camshaft processing, and in particular relates to an optimal design calculation method for camshaft cam fillet milling processing. Background technique [0002] The general calculation scheme of cam fillet milling optimization design is: when using an end mill to mill a cam fillet, the size of the fillet is determined by the fillet size of the insert installed in the tool (what is the insert fillet, and the cam fillet after milling is also How much), to optimize the design, it is only to formulate a variety of schemes (by changing the cutting parameters such as the feed amount and feed speed of the tool) and the processing sequence, to find the most suitable processing parameters to ensure the cam fillet size requirements. [0003] Ordinary cams have small rounded corners, and rely on tool rounded corners to be directly milled to form. The processing technology is relatively common and mature. The wear and milling ...
