Abstract

The invention discloses a processing method for avoiding cutter interference. The processing method is used for developing and processing a low-pressure turbine case weld assembly and comprises the following steps: at first, calculating a proper transformation angle of the taper slot of a part and measuring the deformation of the part to ensure that the allowance is to be processed; then, adoptingan end mill to carry out layered rough mill processing, and according to the processing parameters of the part, reserving 0.2mm allowance for the single side of finish machining; and finally, according to the specific requirements of the taper slot, selecting a proper end mill to carry out finish-milling processing by adopting a correct angle to ensure related size requirements. The processing method effectively ensures the processing quality of the part and effectively solves the problems about cutter interference, low processing efficiency and not-in-place processing caused by part deformation to ensure the processing quality of the part.

Description

technical field [0001] The invention relates to the technical field of mechanical processing of large thin-walled casing parts, in particular to a processing method for avoiding tool interference. Background technique [0002] When traditionally machining the inner circumferential chute of thin-walled parts, in order to avoid tool interference, small-diameter milling cutters are used for rough machining in layers, leaving a margin of 0.2mm on one side, and then finishing milling to ensure the size requirements of the parts. There are three problems in the processing of this method: one is that due to the small diameter of the tool, the processing depth of each layer is small during rough machining, which affects the processing efficiency; the other is that the processing on both sides of the chute is not in place, and there is a margin, which needs clamping Guarantee; the third is affected by the welding deformation of the parts, it is easy to bruise the inside of the parts ...
