Embodiment 1

[0020] Such as Figure 1 to Figure 3 As shown, a method for processing double-sided single-boss thin-walled web parts includes the following steps:

[0021] (1) The machining allowance in the axial direction is reserved according to the thickness of the web part, and the principle that the thinner the thickness of the web part is, the more machining allowance is left in the axial direction, usually the axial The machining allowance is controlled at 3mm-5mm;

[0022] (2) Determine the processing parameters of the web parts: select the rated speed of the machine tool for the number of spindle revolutions to be 2500-24000r / min; the depth of cut is determined to be 2-5mm according to the machining allowance of the web parts in the axial direction; The thickness of the web part is determined to be 0.5-5mm; the feed rate of a single tooth is determined to be 0.15-0.18mm / turn (usually calculated as 0.18mm / turn) according to the thickness of the web part and the tool; After the amou...

Embodiment 2

[0027] Such as Figure 4 to Figure 6 Shown, a kind of processing method of double-sided thin-walled web part, comprises the following steps:

[0028] (1) The machining allowance in the axial direction is reserved according to the thickness of the web part, and the principle that the thinner the thickness of the web part is, the more machining allowance is left in the axial direction, usually the axial The machining allowance is controlled at 3mm-5mm;

[0029] (2) Determine the processing parameters of the web parts: select the rated speed of the machine tool for the number of spindle revolutions to be 2500-24000r / min; the depth of cut is determined to be 2-5mm according to the machining allowance of the web parts in the axial direction; The thickness of the web part is determined to be 0.5-5mm; the feed rate of a single tooth is determined to be 0.15-0.18 mm / turn (usually calculated as 0.18mm / turn) according to the thickness of the web part and the tool; After the amount is ...

Abstract

The invention provides a machining method of a double-face thin-wall web plate part. The method comprises the following steps: (1) remaining machining margin in axial direction according to the thickness of the web plate part; (2) determining machining parameters of the web plate part: main shaft revolution number, cutting depth, cutting width, single-tooth feed and tool feed; (3) determining cutting position; (4) determining cutting angle of the tool; (5) determining a machining mode: firstly machining a web plate on a boss, then machining a web plate on the contour part of the boss, and finally machining the web plate on the bottom surface. During machining of the web plate on the bottom surface, the machining mode and sequence are determined according to the number of the bosses. Through the method, the machined double-face thin-wall web plate meets the technical condition requirements of drawings, the problem of high probability of deformation of a part is solved, secondary correction of an auxiliary process is avoided, and the use of a special auxiliary tool is avoided, so that the machining efficiency is improved and the production cost is reduced.

Description

technical field [0001] The invention relates to a processing method of a double-sided thin-walled web part, belonging to the technical field of mechanical processing. Background technique [0002] In aerospace and other fields, in order to reduce weight and improve mechanical performance, parts are designed to be integrated and thin-walled, which has become a design direction and trend. However, the shortcomings of thin-walled parts during processing have always plagued the production line, such as easy deformation of parts during processing, low processing efficiency, secondary corrections required by auxiliary processes, and high cost of special auxiliary tooling. Contents of the invention [0003] In view of the above deficiencies, the present invention provides a method for processing double-sided thin-walled web parts. [0004] The technical solution of the present invention: a method for processing double-sided thin-walled web parts, comprising the following steps: ...
