Abstract

The invention discloses a processing method for parts. The processing method comprises the following steps: a, drawing the contour of a non-continuous arc narrow-end slot on a to-be-processed part by using a numerical control designing module; b, selecting knives by using a numerical control knife selecting system; c, employing a milling processing mode and setting cutting increment, cutting depth and a cutting mode through numerical control; d, selecting the contour for milling and determining boundaries; and e, automatically milling the non-continuous arc narrow-end slot on the to-be-processed part by using a numerical control programming module. According to the invention, processing efficiency is substantially improved, and numerical control processing only takes 15 min; quality of parts is effectively controlled; processing precision of dimension is guaranteed through adjustment of a milling cutter compensation value; and production cost is reduced.

Description

technical field [0001] The invention relates to the technical field of aero-engine parts processing, in particular to a non-continuous circular arc narrow end groove part of an engine injection oil channel. Background technique [0002] The injection oil passage is an important part of the combustion chamber of the aero-engine, and the non-continuous circular arc narrow end groove is an oil passage. Its main function is the passage of fuel, which sprays fuel to the oil throwing pan through the fuel injection hole, and provides fuel to the engine combustion chamber after the fuel is atomized. [0003] The non-continuous arc narrow end groove has been machined by EDM, and the EDM efficiency is low. Special shaped electrodes are required. The size of the part is directly guaranteed by the forming electrode, and the size and technical conditions of the electrode are strictly required, so the design and manufacture of the forming electrode are more complicated. In the case of ...
