Situation is entered in the milling of another end points or other profile frame line.
The present invention judges that wiring board profile milling enters the methods of technique edges and uses the obtained design outline figure of methods described complete
Meet actual production wiring board in milling profile entirely, the feed of milling cutter takes into full account that what milling cutter itself size brought actually mills out
The influence that profile is not inconsistent with customer requirement, majority milling cutter diameter is 1mm at present, if the wiring board profile of client is not the square of rule
Shape（Most cases are such）, then because milling cutter itself is round, run into re-entrant angle corner position will the non-milling of residual fraction arrive, so as to lead
Reality and different design are caused, and then causes product is unqualified to be forced to do over again or even scrap or customer complaint, is judged by the method
Go out these re-entrant angles position should many millings enter after technique edges, above-mentioned adverse consequences can be avoided completely, additionally, due to it is all judgement all by
Program voluntarily judges, it is to avoid the mistake that human intervention is caused, while whole results can be obtained the short time, then is about to this certainly by program

Enter）, once being learnt during traversal certainly needs milling to enter, then can jump out this traversal, then go to judge another end points or other profile side
Situation is entered in the milling of wire.
With reference to instantiation, the profile of wiring board in the design of the present invention, wiring board profile as shown in Figure 1, figure is described
Wire 1, is provided with one or more recessed position 2 in four sides of profile wire 1, recessed position 2 can for semicircle or fillet or
Right angle.Wherein the lower left corner for the present invention will set 0. 11, if it is exactly this in fact that we, which connect profile frame line,
The circumscribed rectangle of wiring board.
Plus the profile after technique edges is as shown in Fig. 2 it is exactly technique edges 5 than those parts that upper figure has more, in recessed position 2
The recessed position of upper correspondence is exactly that work side 6 is entered in so-called milling, and having most of position also side, also a segment distance, such as fillet phase are entered in milling
Work side 6 is entered in corresponding milling；Some do not enter toward side milling, and work side 6 is entered in such as corresponding milling in right angle：

It is the left side of the circumscribed rectangle of wiring board certain is a bit of, and AB be it is vertical, due to A points do not fall circumscribed rectangle some
Summit, thus at A points should milling enter technique edges, concurrently there are the arc AOC met with AB in A points, and the circumscribed square of point O assist sides
Outside shape and Y_a<Y_o, therefore certain distance should be entered to B end mills.
In addition, to B points position, (as shown in Figure 4) is checked in amplification, this figure is the enlarged drawing of the corner position of B points there, is passed through
Amplification, it is understood that corner is really the false arc connected into by multistage line segment, then now judge that the milling of B points position enters situation then
Should judge the mode that line segment meets with line segment：Because B points all do not fall within certain of the circumscribed rectangle of wiring board profile as A points
On individual summit, thus B points should milling enter the segment distance of technique edges one, and line segment AB and line segment BP meets at B points, due to AB be it is vertical,
And X_b<X_p, therefore B points should be while milling be entered toward another section of line segment AB（This example is A ends）A segment distance is entered in milling.
It can accurately show that situation is entered in all millings according to the method described before, and the method for above-mentioned derivation can pass through program
To realize, so CAM personnel designed lines plate profile the efficiency that will significantly improve, improve design and compatible degree.
