Abstract
The invention relates to a machining method for ultrathin-wall plate edge strips. The machining method comprises the following steps that rough machining is performed by judging the types of ultrathin-wall fillet parts, a certain margin is preserved, the milling is performed after a cutting mode is selected, finally the finish machining is performed, the milling is performed on the ultrathin-wall fillet parts, the cutter quivering phenomenon is avoided, and the production efficiency of the parts is improved.
Description
Technical field
The present invention relates to a kind of method of processing parts, be specifically related to a kind of high thin-walled part edge strip processing method, belong to Aero-Space manufacture field.
Background technology
In order to weight reduction and raising mechanical performance in aerospace field, part is designed to integration, thin-walled property has become design direction and trend, part rib is also to higher thinner future development, numerous parts rib thickness is only 1.2mm or 1.5mm, rib height and thickness ratio are up to 80, if cannot precision be ensured by traditional processing method, rib there will be vibration distortion and causes rib surface light face degree extreme difference and the overproof problem of the extremely uneven local size of thickness distribution, and the phenomenon that even occurs breaking causes part rejection.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of high thin-walled part edge strip processing method, and structure is simple, and convenient operation, increases work efficiency, and ensures construction quality.
For overcoming the above problems, concrete technical scheme of the present invention is as follows: a kind of high thin-walled part edge strip processing method, and it is characterized in that, step is as follows:
1), judge that high thin-walled parts belongs to the open type rib lacking support or the high thin-walled rib part having support;
2), according to the judged result of step 1) process, first carry out roughing, leave 2-4mm surplus;
3), cutting way is selected, the surplus of milling 2-3.5mm according to the judged result of step 1);
4), milling base angle.
Preferably, the cutting way described in step 3) is staggered cutting mode or radial cutting mode.
The beneficial effect that the present invention brings is: first carry out roughing to high thin-walled parts, select cutting way to carry out milling according to condition again, not only reduce high thin-walled parts machining deformation probability, and improve working (machining) efficiency, reduce the second-order correction of aided process, avoid occurring cutter generation of quivering.
Detailed description of the invention
A kind of high thin-walled part edge strip processing method, it is characterized in that, step is as follows:
1), judge that high thin-walled parts belongs to the open type rib lacking support or the high thin-walled rib part having support;
2), according to the judged result of step 1) process, first carry out roughing, leave 2-3mm surplus;
3), cutting way is selected, the surplus of milling 2-3.5mm according to the judged result of step 1);
4), milling base angle.
Preferably, the cutting way described in step 3) is staggered cutting mode or radial cutting mode.
Embodiment one:
Lack the open type rib of support, adopt the processing scheme of staggered cutting, step is as follows:
1) first carry out roughing to rib, sidewall leaves 2-3mm surplus;
2) process in the mode of staggered cutting, axial one deck milling 2mm or 3mm;
3) milling is carried out to part base angle.
Embodiment two:
There is the thin rib of height supported, adopt the processing scheme of radially layered, step is as follows:
1) first carry out roughing to rib, sidewall leaves 3-4mm surplus;
2) process with one-sided cutting way, radial point two-layer carries out cutting 2.5-3.5mm surplus;
3) to step 2) surplus of remaining 0.5-0.8mm carries out fine finishining.
Above-described is only the preferred embodiments of the present invention.It should be pointed out that for the person of ordinary skill of the art, under the premise without departing from the principles of the invention, some modification and improvement can also be made, also should be considered as belonging to protection scope of the present invention.
Claims (2)
1. a high thin-walled part edge strip processing method, it is characterized in that, step is as follows:
