The purpose of the V_BlockCtrMove routine is to allow a circular object to be placed in a V-block.Within this Section:V-Block Center Move (V_BlockCtrMove)
|
Required Inputs:
Object Points:
•ObjPt1: This point is the center of a circular feature. The point may, or may not, have a diameter associated with it.
Target Points:
•TarPt1: The first target surface that the object circle will be tangent to.
•TarPt2: The second target surface that the object circle will be tangent to.
•TarPt3: A point with a diameter associated with it. This diameter is used to calculate the tube locator point.
Directions:
•Dir1: The vector normal to the surface defined by TarPt1.
•Dir2: The vector normal to the surface defined by TarPt1.
•Dir3: The vector along the axis of the circle (cylinder) to be moved to the V-block.
Parts List: The parts listed in this section will be moved based on the object point being translated to a point that is the (radius) distance from the two surfaces on the V block.
Output:
The output is the new position of the object when ObjPt1 is translated to the calculated target point. ObjPt1 will be the tube radius from the target surfaces on the V-Block defined by the target points.
Determine the radius (R1) of the tube from TarPt3.
Offset the V-block planes defined by TarPt1 and TarPt2 by R1. Find the line L1 formed by the intersection of the offset planes of TarPt1 and TarPt2.
Find the point (T3a) at the intersection of line L1 and a plane normal to L1 through TarPt1. Find the point (T3b) at the intersection of line L1 and a plane normal to L1 through TarPt2. Create a point T3 mid way between T3a and T3b.
