structure in a simpler way

If the surface S1 don’t interfere with the lower boundary line one to four more surfaces, named S2, S3, S4, S5, has to be created. The number of surfaces is depending on topology of the head.

Surface S2 starts, in most cases, at the end point of min supporting length, the intersection between the design advice DA_SUPS1 and DA_S1. S2 is a radius. The radius size is, for example, depending on the distance from the intersection between DA_ SUPS1 and DA_S1 to the design advice circle DA_TANCR and max and min limitations. The surface S2 isn’t allowed to be inside the design advice circle DA_TANCR. The start of surface S2 could in some cases be changed depending on radius size and limitations. But the start of S2 isn’t allowed to start closer to the tip seat than the intersection between DA_ SUPS1 and DA_S1. The surface S3 is allowed to be tangent to design advice circle DA_TANCR but not closer to the tip seat. Surface S3 is tangent to radius surface S2 and perpendicular to base plane 3.

Surface S4 is tangent to surface S3 and the exit is at the intersection between upper boundary line and left side boundary line.

If the chip space surface is tangent to surface S4 closer to the base plane 2 than left side boundary line surface S5 has to be created. S5 should be tangent to S4 and the exit is at the intersection between upper boundary line and left side boundary line. S5 should have same angle, AL, as the ship room surface.

In some cases the surface S3 could be excluded. If the calculation of radius size on S2 gives a length of S3 less than zero, the surface S3 will be excluded. If so, the two radii are allowed to be tangent to each other, but not allowed to be wrapover, see figure 3.1.14. The size of S2 will be set without restriction of surface S3. The intersection point, between the two radii, replaces the surface S3 in calculation of positions and sizes.

The maximum distance between base plane 2 and surface S3 is DMM/2 -0.5. If the distance is bigger, measured perpendicular to base plane 1 (Bp1), the surfaces S3 - S5 will be excluded. If so, the surface S2 will be tangent to the surface of D4. This is the only case when the radius, S2, is allowed to be smaller than the min radius. But not smaller than 0.4*min. If so, the radius will be excluded.

The surfaces S2-S5 should be perpendicular to base plane 1 (Bp1).

Limitations

Right limitation means that the surface S3 isn’t allowed to pass the base plane 2, on the insert side, on coupling sizes >=32,

allowed to pass with 5mm on DMM=40

	7mm		DMM=50

	10mm		DMM=60

The surface, radius, S2 should have following radius size:

DMM=16 3.7 min 2.5

DMM=20 4.0 min 2.5

DMM=25 5.0 min 3

DMM=32,40 6.0 min 4

DMM=50 8.0 min 5

DMM=60 10 min 6

if the surface S3 is between the limitations as follow: right limitation and left limitation.

Left limitation is depending on the coupling size and located at the distance of 1/4*DMM measured from base plane 2.

The radius, S2, has to be reduced or increase until it hits the allowed area. The radius isn’t allowed to be reduced more than to min radius.

Radius S2 isn’t allowed to be bigger than the radius S4.

Surface S4, radius, should have following values:

DMM<=25

S4=8

25<DMM<=40 S4=10

40<DMM<=60 S4=12

Answer 2

The provided text describes a complex structure involving multiple surfaces (S1, S2, S3, S4, S5) and their relationships based on specific geometric constraints and limitations. Here’s a simplified breakdown:

1. Surface S1: The primary surface that does not interfere with other surfaces.
2. Surfaces S2 to S5: Created based on the topology of the head and specific geometric rules:
   • Surface S2: Starts at the end point of the minimum supporting length and is a radius. It must not be inside a designated design circle and can be adjusted based on radius size and limitations.
   • Surface S3: Tangent to S2 and perpendicular to a base plane. It may be excluded if its calculated length is less than zero.
   • Surface S4: Tangent to S3 and exits at the intersection of upper and left side boundary lines.
   • Surface S5: Created if the chip space surface is tangent to S4 and must match the angle of the ship room surface.
3. Geometric Constraints:
   • Surfaces S2-S5 must be perpendicular to a base plane.
   • Specific limitations based on coupling sizes dictate how surfaces can interact with base planes and each other.
   • The radius sizes for S2 and S4 are defined by coupling sizes (DMM) with minimum and maximum values.
4. Exclusions and Adjustments: If certain conditions are met (e.g., distance limitations), surfaces may be excluded or adjusted in size.

This structure is governed by specific geometric rules to ensure proper design and functionality based on the intended application.
