Abstract
The invention discloses a numerical machining method of a titanium alloy part. When inner shapes are milled, a broken line or circular arc tool feeding mode is adopted for the programmed tool feeding and retracting mode; machining is carried out according to groove-shaped characteristics, horizontal tool feeding from the opened part is adopted as far as possible for the programmed tool feeding and retracting mode according to a blank structure of a part, if the blank structure is not qualified, spiral tool operation or broken line tool operation is adopted; the tool operation is carried out by selecting the proper helical angle according to the particular situation of a tool, and longitudinal tool operation is forbidden in the program, so that machines, tools and parts can be prevented from being damaged caused by excessive impact generated in machining; speed reduction treatment is carried out at the corner part by the program, and the reduction percentage of the feeding speed can be determined by the size of corner margin and the particular situation of tools. The method can be used for overcoming the problems of high part deformation resilience and rapid cutting edge abrasion after a titanium alloy part is machined in the prior art, and the production efficiency is improved; the chilling phenomenon can be prevented; the machined titanium alloy part is relatively good in durability, and the quality of machined workpieces is ensured effectively.
Description
Technical field
The invention belongs to material processing field, be specifically related to a kind of numerical-control processing method of titanium alloy component.
Background technology
Titanium is a kind of new metallic material just grown up nearly decades, and because it has a series of excellent comprehensive physical mechanical properties such as proportion is little, intensity is high, heat-resisting, corrosion-resistant, facilitating it in the field such as space flight, aviation applies more and more widely; But the machining property of titanium alloy is poor, have impact on widely using of this material.
Summary of the invention
In order to overcome the above-mentioned technical problem that prior art field exists, the object of the invention is to, a kind of numerical-control processing method of titanium alloy component is provided, qualified titanium alloy component can be processed, preventing part work in-process to be out of shape, reduce location and clamping error.
The numerical-control processing method of titanium alloy component provided by the invention, comprises the following steps:
(1), in milling during shape, program forward and back cutter mode adopts broken line or circular arc feed mode; Processing flute profile feature, program forward and back cutter mode adopts from opening wide parts transversely feed according to part blank structure as far as possible, if blahk structure does not satisfy the requirements to adopt under spiral cutter under cutter or broken line, cutter under suitable helical angle is selected according to the concrete condition of cutter, program is forbidden vertically to descend cutter, avoids producing excessive impact in processing and causes lathe, cutter and damage parts;
(2) for avoid cutter on the corner because of cutting output suddenly increase cause broaching tool even breaking milling hinder the probability of part, avoid manual intervention to produce better simultaneously, improve part quality, on the corner program has carried out reduction of speed process, can determine the percentage that feed speed reduces according to the concrete condition of the size of corner surplus and cutter.
Described cutter is yg-type carbide, and described cutting parameter is " low feeding, the slow-speed of revolution, large cutting-in ".
The numerical-control processing method of titanium alloy component provided by the invention, its beneficial effect is, overcomes that part deformation resilience after the processing of original technology machining titanium alloy part is large, the problem of cutting edge quick abrasion, improves production efficiency; Avoid chill phenomenon; The titanium alloy component durability processed is better, effectively ensure that processing work quality.
Detailed description of the invention
Below in conjunction with an embodiment, the numerical-control processing method of titanium alloy component provided by the invention is described in detail.
Embodiment
The numerical-control processing method of the titanium alloy component of the present embodiment, comprises the following steps:
(1), in milling during shape, program forward and back cutter mode adopts broken line or circular arc feed mode; Processing flute profile feature, program forward and back cutter mode adopts from opening wide parts transversely feed according to part blank structure as far as possible, if blahk structure does not satisfy the requirements to adopt under spiral cutter under cutter or broken line, cutter under suitable helical angle is selected according to the concrete condition of cutter, program is forbidden vertically to descend cutter, avoids producing excessive impact in processing and causes lathe, cutter and damage parts;
(2) for avoid cutter on the corner because of cutting output suddenly increase cause broaching tool even breaking milling hinder the probability of part, avoid manual intervention to produce better simultaneously, improve part quality, on the corner program has carried out reduction of speed process, can determine the percentage that feed speed reduces according to the concrete condition of the size of corner surplus and cutter.
The numerical-control processing method of titanium alloy component, overcomes that part deformation resilience after the processing of original technology machining titanium alloy part is large, the problem of cutting edge quick abrasion, improves production efficiency; Avoid chill phenomenon; The titanium alloy component durability processed is better, effectively ensure that processing work quality.
Claims (1)
1. a numerical-control processing method for titanium alloy component, is characterized in that: in (1) milling during shape, and program forward and back cutter mode adopts broken line or circular arc feed mode; (2) flute profile feature is processed, program forward and back cutter mode adopts from opening wide parts transversely feed according to part blank structure as far as possible, if blahk structure does not satisfy the requirements to adopt under spiral cutter under cutter or broken line, select cutter under suitable helical angle according to the concrete condition of cutter, program is forbidden vertically to descend cutter; (3) on the corner program carries out reduction of speed process, can determine the percentage that feed speed reduces according to the concrete condition of the size of corner surplus and cutter.
