A3018174_80063_DP_0001_G casting drawing NEW.pdf

This document is a technical engineering drawing for a case connector casting component. The drawing specifies detailed manufacturing requirements for a pressure-tight casting assembly that will serve as an interface connector.

The casting must meet Class 4, Grade C specifications per MIL-E-6621 and comply with pressure-tight application standards per MIL-STD-276, Method B. Key material requirements include aluminum alloy 356 per QQ-A-591, with all cast surfaces sized at 3/32 inch unless otherwise specified. The drawing establishes tolerance and dimension standards using correlated datums indicated by symbols [X], [Y], and [Z]. Critical specifications include: flash and parting line removal requirements; stock allowances for subsequent machining on indicated surfaces; a maximum draft angle of 10 degrees for internal surfaces; edge radii specifications ranging from 0.5 to 1.5 inches maximum; and sharp edge tolerances of 0.50 inch maximum. The casting must be free of external protrusions, with all raised characters to be 0.32 inches high in Gothic style font positioned approximately as shown. Impregnation is permitted per MIL-STD-276, Method B. The document includes revision notes indicating modifications dated 8/27/2023, with drawing number A3018174 and specifications cross-referenced to document 6159375. Multiple sectional views (A-A, B-B, C-C, and D-D) provide comprehensive dimensional guidance for manufacturing validation.
