Description
Technical field
The present invention relates to a kind of milling method for car light LED-PES reflecting surface.
Background technology
LED-PES speculum is Component units important in automobile lamp, and small product size is little, complex structure, and face type Curvature varying is large, and effects on surface precision and surface quality have high requirements.The structure of PES reflecting surface part is mainly divided into two parts: the functional surfaces such as the positioning supports of convex bowl-shape reflecting surface and periphery, and wherein bowl-shape reflecting surface requires the highest, LED-PES reflecting surface part schematic diagram as shown in Figure 1.
General NC milling, uses larger cutter to overall fine finishining, then carries out the back chipping of local.This all can cause back chipping lapping defect, affects product appearance and precision.If use small-sized cutter fine finishining, that is for through Overheating Treatment, and the PES reflecting surface part that hardness is higher, just likely occurs the problems such as tool wear.
In addition, the processing cutter track of reflecting surface, require that step pitch is even, direction is neat, machined surface can not occur the lapping defect between different cutter track, preferably adopt the disposable processing of a kind of tool path pattern.So how to select cutter track track, it is also the problem needing to consider.
Summary of the invention
The object of this invention is to provide a kind of milling method for car light LED-PES reflecting surface, described processing method adopts the cutter of reasonable size, reflecting surface and periphery functional surfaces are processed separately, and reflecting surface surplus is decomposed processing, ensure that cutter track does not exist knuckle, turn avoid lapping defect, in order to solve general NC milling mode, can lapping defect be caused, affect the problem of product appearance and precision.
For achieving the above object, the solution of the present invention is: a kind of milling method for car light LED-PES reflecting surface, and described processing method comprises:
(1) select the cutter being less than the minimum R angle of machined surface, ensure 1.2 times of the tool radius minimum R angles being still less than described machined surface, cutter track turning arranges knuckle;
(2) be provided separately protective surface processing to the reflecting surface of car light LED-PES speculum and periphery functional surfaces, reflecting surface and functional surfaces junction, periphery arrange handing-over fillet, in process, in handing-over fillet place's transition of reflecting surface and periphery functional surfaces;
(3) fine finishining reflecting surface cutter track, adopts contour processing and plane machining two kinds of modes to mix, and arranges different surplus modes, reflecting surface surplus is decomposed into axial surplus and radial slack is processed.
Further, according to the milling method for car light LED-PES reflecting surface of the present invention, in described step (2); during processing reflecting surface, periphery functional surfaces arranges protective surface, during processing periphery functional surfaces; reflecting surface arranges protective surface, wherein fillet place processing twice.
Further, according to the milling method for car light LED-PES reflecting surface of the present invention, in described step (2), during processing reflecting surface, periphery functional surfaces arranges the protective surface of 0.1mm; During processing periphery functional surfaces, reflecting surface arranges the protective surface of 0.1mm.
Further, according to the milling method for car light LED-PES reflecting surface of the present invention, in described step (1), knuckle is 0.1 times of tool diameter.
Further, according to the milling method for car light LED-PES reflecting surface of the present invention, in described step (3), add man-hour contour, radial slack is set to 0, and axial surplus is set to 0.03mm; When plane machining, axial surplus is set to 0, and radial slack is set to 0.03mm.
The beneficial effect that the present invention reaches: 1, processing method of the present invention selects rational tool dimension, has both ensured that processing puts in place, ensures that again cutter track does not exist knuckle, prevents from shaking and cut.
2, reflecting surface and periphery functional surfaces are processed by the present invention separately, even if there is lapping defect also at fillet place, can ignore.
3, reflecting surface surplus is decomposed processing by the present invention, and between different tool path pattern, handing-over has transition, both ensure that precision, and turn avoid lapping defect.
Accompanying drawing explanation
Fig. 1 is LED-PES reflecting surface part schematic diagram;
Fig. 2 is that the present invention is provided separately protective surface processing to reflecting surface and outer peripheral face, joins the schematic diagram in fillet.
Detailed description of the invention
Below in conjunction with accompanying drawing and specific embodiment, the present invention is further detailed explanation.
The invention provides a kind of milling method for car light LED-PES reflecting surface, by adopting the cutter of reasonable size, reflecting surface and periphery functional surfaces are processed separately, and reflecting surface surplus is decomposed processing, ensure that cutter track does not exist knuckle, turn avoid lapping defect.
Concrete processing method of the present invention is as follows:
Select the cutter being less than the minimum R angle of machined surface, ensure 1.2 times of the tool radius minimum R angles being still less than described machined surface, the R angle of such as 1mm, selects the ball head knife of radius 0.75mm.Cutter track turning arranges knuckle, and knuckle is 0.1 times of tool diameter.The present invention, by selecting rational tool dimension, has both ensured that processing puts in place, ensures that again cutter track does not exist knuckle, prevents from shaking and cut.
As shown in Figure 2, protective surface is provided separately to the reflecting surface of car light LED-PES speculum and periphery functional surfaces and processes, and in handing-over fillet place's transition of reflecting surface and periphery functional surfaces, that is:, when processing reflecting surface, periphery functional surfaces arranges the protective surface of 0.1mm; During processing periphery functional surfaces, reflecting surface arranges the protective surface of 0.1mm, wherein fillet place processing twice.The present invention, by by reflecting surface and periphery functional surfaces separate machined, even if there is lapping defect also at fillet place, can ignore.
Fine finishining reflecting surface cutter track, adopting contour processing and plane machining two kinds of modes to mix, processing by arranging different surplus modes, that is: reflecting surface surplus is decomposed into axial surplus and radial slack, contourly add man-hour, radial slack is set to 0, and axial surplus is set to 0.03mm; During plane machining, axial surplus is set to 0, and radial slack is set to 0.03mm.The present invention is by decomposing processing by reflecting surface surplus, and between different tool path pattern, handing-over has transition, both ensure that precision, and turn avoid lapping defect.
