INFINITY SKIES UNIFIED MODULAR MECHANICAL STANDARD

The governing engineering framework for all Infinity Skies products, systems, and interfaces.

The Infinity Skies Unified Modular Mechanical Standard (UMMS) defines the mechanical architecture, interface logic, datum structure, and interoperability rules that govern all Infinity Skies-designed components, assemblies, and systems.

This standard exists to eliminate ad-hoc mechanical design, reduce system integration complexity, and enable scalable, reconfigurable, long-lifecycle industrial and aerospace hardware platforms.

Purpose and Scope

This standard establishes a unified mechanical language across all Infinity Skies products. It governs how components interface, align, mount, stack, reference, and integrate at every level from individual machined parts to full system assemblies.

The scope of this standard includes, but is not limited to:

  • Machined interface plates
  • Fixture and tooling components
  • Structural interface blocks
  • Equipment mounting systems
  • Test and automation assemblies
  • Ground support equipment (GSE)
  • Modular frames, carts, and platforms

All Infinity Skies products either fully comply with this standard or explicitly declare deviations.

Core Design Philosophy

Modularity First

All components are designed as reusable modules, not single-use parts. No component exists without the intent of reuse across multiple systems and applications.

Interface Ownership

Interfaces are more valuable than individual parts. Infinity Skies owns and controls its mechanical interfaces to ensure long-term compatibility and system continuity.

Datum Discipline

Every component is designed around defined primary, secondary, and tertiary datums to ensure predictable alignment and repeatable assembly.

System Scalability

All designs must support expansion, stacking, adaptation, or recombination without requiring redesign of existing components.

This preserves system integrity while allowing controlled exceptions.

Unified Interface Grid

All Infinity Skies components are governed by a standardized interface grid that defines hole spacing, fastener logic, and alignment references.

Standard Interface Grids

  • Primary Metric Grid: 25 mm
  • Secondary Imperial Grid: 1.000 in

These grids may be overlaid or combined where required to support legacy equipment integration.

Rules

  • Hole patterns align to grid intersections
  • Fastener sizes are standardized by grid tier
  • Grid origin references primary datums

This ensures cross-compatibility between product families and future expansions.

Datum Architecture

Every Infinity Skies component defines a consistent datum structure:

  • Datum A: Primary mounting or reference face
  • Datum B: Orthogonal alignment face or edge
  • Datum C: Secondary alignment or rotational control feature

Rules

  • Datums must be explicitly defined on drawings
  • Functional interfaces reference datums, not features
  • Stack-ups are controlled through datum chains

This enables predictable alignment across assemblies without manual fitting.

Fasteners and Hardware Standards

Fasteners are selected to balance strength, availability, and serviceability.

Standard Practices

  • Metric fasteners preferred (ISO)
  • Socket head cap screws as default
  • Dowel pins used for precision alignment
  • Thread engagement follows best practices

Non-standard fasteners are minimized and must be justified.

Materials and Finishes

Standard Materials

  • 6061-T6 Aluminum (default)
  • 7075-T6 Aluminum
  • Carbon Steel
  • Stainless Steel

Standard Finishes

  • As-machined
  • Clear anodize
  • Black anodize
  • Chemical film
  • Protective coatings as required

Material and finish selections are driven by structural, environmental, and lifecycle requirements.

Tolerances and Quality Control

Infinity Skies components are designed for manufacturability while maintaining functional precision.

Standard Controls

  • Flatness, parallelism, and perpendicularity are controlled on interface surfaces
  • Precision bores and locating features are tolerance-driven
  • Cosmetic features are secondary to functional performance

Inspection-critical features are explicitly called out on drawings.

Configuration Control and Traceability

Infinity Skies maintains configuration control across all products and revisions.

Rules

  • Each product has a unique SKU and revision state
  • Changes are documented and traceable
  • Backward compatibility is preserved whenever possible

This ensures long-term supportability for deployed systems.

System-Level Interoperability

The Unified Modular Mechanical Standard ensures interoperability across product families, enabling:

  • Cross-family mounting
  • System reconfiguration
  • Incremental system growth
  • Reduced custom engineering

Products are designed to function independently or as part of larger assemblies.

Compliance and Deviations

All Infinity Skies products are designed to comply with this standard unless explicitly stated.

Deviation Policy

  • Deviations are documented
  • Rationale is recorded
  • Compatibility impacts are assessed

This preserves system integrity while allowing controlled exceptions.

Who This Standard Serves

  • Aerospace & defense engineers
  • Automation and robotics teams
  • Industrial system integrators
  • Test and qualification engineers
  • Manufacturing and operations teams

This standard exists to accelerate engineering outcomes without sacrificing control.
