H-Plane Split-Block Housing Assembly

Create a symmetrical H-plane split-block housing (35.00 mm × 35.00 mm uniform outer cross-section, total longitudinal length 65.80 mm spanning Z = -6.40 mm to +59.40 mm) separated at the horizontal parting plane Y = 0 into an Upper Block (+Y) and a Lower Block (-Y). Internal Cavity & Transitions Subtract the symmetric 27-zone WRD-650D28 double-ridge corrugated vacuum profile centered at X = 0 (channel width a = 20.85 mm, height b = 10.69 mm, constant ridge width w = 4.57 mm). From Z = 0.00 to 9.30 mm, apply a linear gap taper ramping from 2.69 mm down to 1.60 mm. Follow with Element #1 from Z = 9.30 to 10.70 mm at constant gap 1.60 mm. Alternate 24 core elements from Z = 10.70 to 43.70 mm using 1.40 mm long capacitive teeth at gap 1.25 mm and 1.35 mm long inductive grooves at gap 4.20 mm. Finish with Element #25 from Z = 42.30 to 43.70 mm at gap 1.60 mm, and a linear output taper from Z = 43.70 to 53.00 mm ramping from 1.60 mm back to 2.69 mm. Extend uniform 2.69 mm access tunnels through the end flange zones (Z = -6.40 to 0.00 mm and Z = 53.00 to 59.40 mm). Fasteners, Counterbores, Tapped Holes & Dowels • 4-40 Assembly Screws: Drill four through-holes (Ø3.00 mm clearance) parallel to the Z-axis at (±13.97 mm, ±13.97 mm) piercing completely through the Upper Block. On the matching coordinates of the Lower Block, create 4-40 UNC tapped holes (Ø2.35 mm tap drill, depth 12.00 mm) accessible from the bottom exterior face (Y = -17.50 mm). Add socket-head counterbores (Ø5.60 mm diameter, depth 4.00 mm) on the bottom exterior face of the Lower Block aligned with each of the four 4-40 tapped holes. • Parting-Line Alignment Dowels: Along the Y = 0 mating interface, subtract two transverse alignment dowel holes (Ø2.37 mm, depth 6.00 mm total, split evenly across Y = 0) located at (-12.00 mm, 0.0 mm, Z = 10.00 mm) and (+12.00 mm, 0.0 mm, Z = 43.00 mm). • Mating Flange Dowel Pins: On the input flange face (Z = -6.40 mm) and output flange face (Z = 59.40 mm), position two alignment dowel pins (Ø2.37 mm, protruding outward by 2.50 mm) at (-9.50 mm, +9.50 mm) and (+9.50 mm, -9.50 mm) on each end face.
