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
The present invention relates to a kind of processing method of two-sided thin-wall web plate part, belong to Machining Technology field.
Background technology
In fields such as Aero-Space, in order to weight reduction, improve mechanical performance, part is designed to integration, thin-walled property has become design direction and trend.And thin-walled parts annoyings production line adding the deficiency shown man-hour always, as yielding in part processing, working (machining) efficiency is low, need aided process to carry out second-order correction, dedicated accessory tool use cost is high.
Summary of the invention
For above deficiency, the invention provides a kind of processing method of two-sided thin-wall web plate part.
Technical scheme of the present invention: a kind of processing method of two-sided thin-wall web plate part, comprises the following steps:
(1) leave and take allowance in the axial direction according to the thickness of web part, and the thickness following web part is thinner, leave and take the more principles of allowance in the axial direction, usually controls at 3mm-5mm by allowance axially;
(2) machined parameters of web part is determined: spindle revolutions selects the rated revolution of lathe; Cutting-in is determined according to web part allowance in the axial direction; Cut the wide thickness according to web part to determine; The monodentate amount of feeding is determined according to the thickness of web part and cutter; Tool feeding is determined again after spindle revolutions and the monodentate amount of feeding are determined;
(3) determine lower cutter position: for the little vallecular cavity web of web area≤100mm × 100mm, its lower cutter position is selected at close rib place; For the large vallecular cavity web of web area > 100mm × 100mm, its lower cutter position is selected in an arbitrary point;
(4) cutting angle of cutter is determined: the cutting angle of cutter controls within 3 °;
(5) determine processing mode: first process boss epiplastron, reprocessing boss profile place web, finally processes bottom surface web.
When carrying out processing bottom surface web, if the quantity of vallecular cavity inner convex platform is one, then need to select from inner principle of processing toward outer ring to process bottom surface web.
When carrying out processing bottom surface web, if the quantity of vallecular cavity inner convex platform is two or more, then needing bottom surface web to be first divided into several well-behaved parts, then locating web I according to first processing between boss---reprocessing large area place web II---and finally process the principle of small size place web III to process bottom surface web.
Beneficial effect of the present invention: by adopting the present invention, the two-sided thin-wall web plate after processing is made to meet the requirement of drawing technical conditions, not only overcome and process yielding problem because web trembles the part brought, stop aided process second-order correction, and avoid the use of dedicated accessory tool, therefore improve working (machining) efficiency, reduce production cost.
