Abstract

The invention belongs to the related technical field of metal cutting machining and discloses a compound oblique plane milling machining method for high-precision surface roughness control.The method comprises the steps that (a) a workpiece is machined in a plunge milling mode, and multiple process parameters are acquired; (b) instantaneous cutting widths under the different plunge milling machining conditions are respectively calculated according to an optimizing formula; (c) the calculated instantaneous cutting widths are utilized to establish a required cutter instantaneous dynamic total cutting force prediction model, and corresponding guidance is provided according to the model to complete the plunge milling machining process.By the adoption of the method, comprehensive and accurate prediction on the cutting force in the plunge milling machining process can be achieved under the condition that technical machining requirements are strictly met, and accordingly the process guidance is provided for the high-quality efficient plunge milling control process.Therefore, the method is especially suitable for the plunge milling machining occasions of impellers, casings and other grooved parts.

Description

technical field [0001] The invention belongs to the technical field related to metal cutting, and more specifically relates to a cutting force prediction modeling method for plunge milling. Background technique [0002] Slot parts such as impellers and casings are usually made of high-temperature alloys. Currently, point milling and layer milling are mainly used for processing such parts with complex shapes and special materials. However, these processing methods have the characteristics of low processing efficiency and fast tool wear. Due to the high material removal rate and other characteristics of plunge milling, it can be used to process complex-shaped parts with grooves, which greatly improves production efficiency and reduces production costs. [0003] The plunge milling method, also known as the axial feed milling method, is one of the methods to achieve high material removal rate milling. In addition, plunge milling is more efficient than conventional face milling....
