First penetrates face.
Using M1 as boundary, the opposite direction of P point to M1 is vector, obtains face SPlane i.e. first of penetrating with boundary and penetrates face.
Step 204: judging that first penetrates between face and the second curved surface with the presence or absence of intersection；If it exists, 205 are thened follow the steps；
If it does not exist, 206 are thened follow the steps.
It is penetrated between face and the second curved surface by judging first with the presence or absence of intersection, can determine first surface, the second curved surface
Between transitional type；Specifically, intersection if it exists, then transitional type is outer transition；Intersection if it does not exist, then transitional type be
Interior transition.
Step 205: intersection if it exists, transition face or cylinder transition are intersected in building between first surface and the second curved surface
Face.
When the transitional type between first surface and the second curved surface belongs to outer transition, need to construct transition machined surface.Institute
The transition machined surface of building can set for intersection transition face or cylinder transition face, those skilled in the art according to realization demand
Set the specific type of constructed transition machined surface.
A kind of mode preferably constructing cylinder transition face between first surface and the second curved surface is as follows:
Firstly, determining the intersecting lens of first surface and the second curved surface；
Secondly, using the upper point of intersecting lens, lower point as axis, water jet radius is radius, do the first offset bus of connection and
Third deviates bus cylindrical surface, using cylindrical surface as the cylinder transition face between the first surface and the second curved surface.

The offset bus that processing sequence is located at last in line set is redefined as the first offset bus, and returns to execution sub-step
For S1 using the first offset bus as axis, water jet radius is the step of radius constructs the first cylinder, repeats step S1 to step
Rapid S3 is until the intersection volume of the first cylinder and the second curved surface is sky；
The intersection volume of first cylinder and the second curved surface is not sky, then illustrates that initial water jet cylinder intersects with face is faced, this kind
In the case of first surface, the positional relationship of the second curved surface it is as shown in Figure 8.
S4: if it is empty, then the offset bus in the first offset bus set is deleted according to the second preset rules.
The intersection volume of first cylinder and the second curved surface is sky, then illustrates initial water jet cylinder and non-intersecting, this kind that face face
In the case of first surface, the positional relationship of the second curved surface it is as shown in Figure 9.
Wherein, sub-step S4 carries out deletion tool to the offset bus in the first offset bus set according to the second preset rules
Body includes following sub-step:
S41: deleting the first offset bus in the first offset bus set, will add in current first offset bus set
The offset bus that work sequence is located at last is redefined as the first offset bus；
S42: using the first offset bus as axis, water jet radius is that radius constructs the second cylinder；
S43: whether the intersection volume for judging the second cylinder and the second curved surface is empty；
S44: if not empty, then the first offset bus is deleted in the first offset bus set, current first is deviated
The offset bus that processing sequence is located at last in bus set is redefined as the first offset bus, and returns and execute S42
Using the first offset bus as axis, water jet radius is the step of radius constructs the second cylinder, repeats step S42 to step
S44, until the intersection volume of the second cylinder and the second curved surface is sky；
S45: if it is empty, then whole offset buses in current first offset bus set is connected, it is bent to form the second batten
Face；
S46: judge the second spline surface and the second curved surface with the presence or absence of intersection；
S47: if it exists, then executing S41 and delete the first offset bus in the first offset bus set, will be current
The offset bus that processing sequence is located at last in the first offset bus set is redefined as the first offset bus
Step；
S48: if it does not exist, then retain whole offset buses in current first offset bus set.
Interior transition processing is carried out to the second curved surface in the same way, specific process flow includes following sub-step:
First sub-step: whole offset buses in connection the second offset bus set form the second spline surface；
Second sub-step: judge the second spline surface and first surface with the presence or absence of intersection；
Third sub-step: if it exists, then second deviated in bus set, deleted with the offset bus of first surface heteropleural
It removes；
4th sub-step: if it does not exist, then retain whole offset buses in the second offset bus set.
The concrete mode that second is deviated in bus set, is deleted with the offset bus of first surface heteropleural, referring to by the
The concrete mode deleted in one offset bus set, with the offset bus of the second curved surface heteropleural is right in the embodiment of the present invention
