The method has the advantages that: 1, the method provides the key for cutting edge gap back milling cutter numerical control machining, and ensures the normal height of the cutting edge so as to ensure the machining precision; 2, the method has simple operation, flexible parameter input and wide application range; and 3, when the cutter path is calculated, factors such as chuck interference, tool bit interference, corner deceleration, smoothening treatment on taper angles and the like are comprehensively considered, and the most reasonable cutter path is generated on the premise of safety. The invention finally realizes high-efficiency and precise cutting edge gap back milling cutter automatic numerical control machining.
Description
Technical field:
The present invention relates to a kind of CAM processing method of cutting edge gap, especially use the cutting edge gap processing method of back of the body milling cutter.
Background technology:
Trimming edge is the key component of diel forming part, and for the smooth and easy blanking of energy, the counter blade open height generally all has dimensional requirement.This just need guarantee that modal way is that mould is inverted processing from the negative by processing method, but this is unworkable at all to large mold.Effective method is to use the processing of back of the body milling cutter, but present CAM software also not have special back of the body milling process at cutting edge gap.And often the cutting edge height is treated to the solid surplus by the cutting edge gap program that additive method obtains, mistake on this theory of computation not only makes operation waste time and energy, and dimensional discrepancy very big (do not wait because of the cutting edge height is different, maximum can reach several mm) can not satisfy production requirement.
Summary of the invention:
Purpose of the present invention just is to improve the Computerized Numerical Control processing technology of cutting edge gap, has proposed a kind of numerical-control processing method that uses back of the body milling cutter, makes the procedure of cutting edge gap generate simply, and has well guaranteed dimensional accuracy effectively to have improved production efficiency.
Technical scheme of the present invention is: a kind of back of the body milling cutter Computerized Numerical Control processing technology of cutting edge gap is characterized in that: carry out according to the following step: (1) input solid also is provided with machined parameters such as cutting edge height, the final surplus in cutting edge side, cutting edge gap side margins; (2) go out final following cutting edge line according to calculation of parameter such as profile surplus, the final surpluses of cutting edge height and cutting edge side; (3) following cutting edge line is according to the back of the body milling cutter processing cutter rail that calculates cutting edge gap in conjunction with the cutting edge gap side margins.
Advantage of the present invention is: 1, proposed the key point of key for cutting edge gap back milling cutter digital control processing, guaranteed the normal direction height of cutting edge, thereby guaranteed machining accuracy; 2, this method is simple to operate, and flexible parameter input is applied widely; 3, when calculating the cutter rail, take all factors into consideration factors such as chuck interference, cutter head interference, corner deceleration, sharp corner fairing processing, under the prerequisite of safety, generated the most rational cutter path.Efficient, the precise cutting edge gap back milling cutter automatic numerical control machining of final realization.
Description of drawings:
Fig. 1 is a FB(flow block) of the present invention.
Fig. 2 is a cutting edge gap program example.
Fig. 3 is the partial enlarged drawing of Fig. 2.
The specific embodiment:
As shown in Figure 1: a kind of back milling cutter numerical control machining method of cutting edge gap, carry out according to the following step: (1) input solid, cutter also is provided with machined parameters such as cutting edge height, the final surplus in cutting edge side, cutting edge gap side margins; (2) calculate the cutting edge line according to the final surplus of profile surplus and cutting edge side; (3) according to the cutting edge height last cutting edge line is setovered and obtain final following cutting edge line; (4) following cutting edge line is according to the back of the body milling cutter processing cutter rail that calculates cutting edge gap in conjunction with the cutting edge gap side margins.
Shown in Fig. 2,3: cutting edge gap generally adopts back of the body milling cutter to process, and wherein the cyan face is a trimming edge.Compare lamellar body model (sheet body), physical model (solid body) has shortcomings such as precision is low, data volume big, difficult modification, so the processing of 3D cutter rail is according to the general lamellar body that adopts.Entity shown in Figure 1 is not the processing foundation only for saying something.Line 1 shown in Figure 1 is theoretical three-dimensional trimming edge die parting line (not considering to expect thick and the deburring gap), line 2 be the following cutting edge line of cutting edge height (normal direction height) during for 15mm (consider that simultaneously negative material is thick :-1mm, the deburring gap :-0.05mm).Following cutting edge line is a key point of calculating the cutting edge gap program, can obtain by two kinds of methods: the one, directly do three-dimensional biasing and obtain by the three-dimensional trimming edge die parting line of theory, only be applicable to and do not consider to expect thick and the situation deburring gap, and prerequisite is that three-dimensional die parting line is wanted accurately; The 2nd, be that reference line calculates down the cutting edge line by the lamellar body model with the die parting line, advantage is that the Z value of split pattern line does not have required precision, is applicable to any situation, when especially the lamellar body model need be revised repeatedly.Obtaining down after the cutting edge line just can be to have carried on the back the cutter rail of milling cutter according to calculating according to this, shown in figure center line 3 (the cutting edge gap side margins :-1.5mm), to note chuck interference, cutter head interference, corner deceleration (corner's cutting output is big), sharp corner fairing processing etc. simultaneously.
Fig. 3 is the partial enlarged drawing of Fig. 2, can be clear that the effect that covers of using back of the body milling cutter processing cutting edge gap, thereby guarantees the normal direction height unanimity of cutting edge.
