Method for machining thin-walled components

Abstract

The invention discloses methods for machining thin-walled components, relates to the field of machining, and particularly relates to a method for machining thin-walled components. The method includes steps that thin-walled portions and other portions are roughly machined together, machining allowance of 1 mm needs to be reserved at wide locations of the thin-walled portions to prevent the thin-walled portions from deforming due to high speeds and engagement of cutting edges during rough machining, rough machining modes should be surrounding cutter feeding modes, and cutters are spirally extended to the side walls of the thin-walled components from the peripheries to the middles of the thin-walled components in each cutter feeding procedure; the cutters are selectively end milling cutters with tungsten steel cutters, so that deformation of the thin-walled portions due to impact force generated when the cutters approach the thin-walled portions can be effectively reduced, and requirements on sufficient strength of the cutters can be met; top curved surfaces are subjected to semi-finish machining, 6mm spherical cutters are selected for carrying out semi-finish machining on the top curved surfaces, excessive defective materials are removed, and accordingly uniform finish machining allowance can be reserved. The method has the advantages that the method is easy and convenient to implement, the machining quality and the machining precision of workpieces can be guaranteed, the production efficiency can be improved, and the production cost can be reduced.

Description

technical field [0001] The invention relates to the field of mechanical processing, in particular to a processing method for thin-walled parts. Background technique [0002] Thin-walled electrode parts are very common in the mold manufacturing process, such as the processing of digital, mobile phone, casing and other product molds is particularly important, thin-walled electrodes are also called bones in the mold industry. Copper and copper alloys are usually used as electrode materials. Such thin-walled electrode parts have simple structures, high and thin walls, and large machining allowances. However, copper and copper alloys have low strength and hardness and large linear expansion coefficients, so the processability is poor. Under the influence of cutting force, cutting heat, cutting vibration and other factors, machining deformation is easy to occur, and it is difficult to control machining accuracy and improve machining efficiency. The precision thickness change req...
