The T-shaped part by numerical control machining deformation of elongated complexity control method
Technical field
The invention relates to a kind of part by numerical control machining deformation control method, relates in particular to the T-shaped part by numerical control machining deformation of a kind of elongated complexity control method.
Background technology
Originally in digital control processing field, if run into elongated T-shaped part, can in every procedure of process, all produce part deformation, finally proofread and correct difficultly, probably have a strong impact on the final processing dimension of part and cause part to be scrapped.Therefore, the Deformation control in machining is very important for follow-up processing, and it directly affects the crudy of subsequent parts.
Summary of the invention
The object of the invention is to provide the T-shaped part by numerical control machining deformation of a kind of elongated complexity control method, can in NC Machining Process, eliminate the afterbody distortion of weld parts front assembly, and deflection is removed.
The technical scheme of the invention: the T-shaped part by numerical control machining deformation of elongated complexity control method, comprises the steps:
1) the processed T-shaped part of elongated complexity is divided into left and right two subassemblys, i.e. subassembly I and subassembly II;
2) subassembly I and subassembly II are carried out to roughing and made positioning datum plane and locating hole;
3) subassembly I and subassembly II are fixed on CNC milling machine processing table top by fixing tool;
4) adopt the shallow processing mode of cutting to carry out the contour layer ring cutting that fall to part;
5) to the reserved allowance in assembling position;
6) subassembly I and subassembly II are welded into as a whole and are heat-treated;
7) complete the T-shaped part machinery process of elongated complexity.
The concrete grammar of described step 4) is: adopt the contour cutting way that falls layer in both sides, machine spindle speed is 220~300RPM, and cutting depth is 0.5~2mm, and cutting width is 60~70mm, feed speed is 700~1000mm/min, and adopts the modular cutting tool assembly of end mill body and blade welding.
The beneficial effect of the invention: adopt the shallow processing mode of cutting to carry out the contour layer ring cutting that fall in both sides to part, by improving machine spindle speed, reduce cutting depth, increase cutting width, increase feed speed, and the modular cutting tool assembly that adopts end mill body and blade to weld, make material stress in working angles along with the discharge of cutting has obtained sufficient release, reduce stress and concentrated the part deformation causing, eliminate the afterbody distortion of weld parts front assembly, working (machining) efficiency also improves thereupon, can improve more than 30%, has greatly shortened the manufacturing cycle of part.

The specific embodiment
The T-shaped part by numerical control machining deformation of elongated complexity control method, as shown in Figures 1 to 4, comprises the steps:
1) the processed T-shaped part of elongated complexity is divided into left and right two subassemblys, i.e. subassembly I and subassembly II;
2) subassembly I and subassembly II are carried out to roughing and made positioning datum plane and locating hole;
3) subassembly I and subassembly II are fixed on CNC milling machine processing table top by fixing tool;
4) adopt the shallow processing mode of cutting to carry out the contour layer ring cutting that fall to part;
5) to the reserved allowance in assembling position;
6) subassembly I and subassembly II are welded into as a whole and are heat-treated;
7) complete the T-shaped part machinery process of elongated complexity.
The concrete grammar of described step 4) is: adopt the contour cutting way that falls layer in both sides, machine spindle speed is 220~300RPM, and cutting depth is 0.5~2mm, and cutting width is 60~70mm, feed speed is 700~1000mm/min, and adopts the modular cutting tool assembly of end mill body and blade welding.
It is shallow that to cut processing be AF1410(16Co14Ni10Cr2Mo to this kind of material trademark) processing of unimach is a kind of new processing mode.
Now selecting a φ 63R4 cutter is example, and the shallow concrete cutting parameter of cutting processing and tradition processing contrasts as follows:
Can find out and adopt shallow superiority of cutting processing mode from upper table analysis.
