Custom automated machinery represents significant engineering investment, but the process of designing and building these systems can seem mysterious to those outside the automation industry. Understanding how custom machines are developed helps set realistic expectations and ensures successful project outcomes.
Phase 1: Discovery and Requirements Definition
Every custom automation project begins with thorough requirements gathering. This phase establishes the foundation for all subsequent engineering work.
Understanding the Application
The automation integrator's team works to understand:
- The product being manufactured—geometry, materials, tolerances, weight
- Current process if one exists—how the operation is performed today
- Pain points driving the automation need—labor, quality, capacity, safety
- Integration requirements with upstream and downstream equipment
- Facility constraints including available space, utilities, and environment
Defining Success Criteria
Clear project objectives must be established:
- Throughput targets—parts per hour, shift, or year
- Quality requirements—acceptable defect rates, measurement tolerances
- Flexibility needs—how many product variants, changeover time requirements
- Budget parameters—investment range and ROI expectations
- Timeline—when production must begin
Feasibility Assessment
Before committing to full development, experienced integrators assess:
- Technical feasibility—can the process be automated reliably?
- Economic feasibility—does the ROI justify the investment?
- Risk factors—what could prevent success?
This may include concept studies, proof-of-concept testing, or simulation modeling for complex applications.
Phase 2: Concept Development
With requirements defined, engineering begins developing the automation concept.
Process Development
For new processes, engineers determine:
- How the manufacturing operation will be performed
- What technologies will accomplish each task
- The sequence of operations
- Cycle time estimates for each step
Process development may require testing with customer parts to validate assumptions.
Mechanical Concepts
Mechanical engineers develop preliminary layouts showing:
- Overall machine footprint and arrangement
- Major component placement (robots, presses, conveyors)
- Operator stations and access points
- Material flow through the system
- Safety guarding approach
Multiple concepts may be explored before selecting the optimal approach.
Controls Architecture
Controls engineers define:
- PLC platform selection
- Robot controller requirements
- Vision system specifications
- HMI approach and operator interface
- Network architecture and connectivity
- Safety system requirements
Technology Selection
Key component decisions are made:
- Robot make, model, and payload
- Servo systems and drives
- Sensors and measurement devices
- Tooling and fixture concepts
- Material handling mechanisms
Concept Review
The concept package is reviewed with the customer, including:
- Layout drawings and 3D models
- Process flow descriptions
- Cycle time analysis
- Preliminary cost estimate
- Project schedule
Customer approval of the concept enables detailed engineering.
Phase 3: Detailed Engineering
Detailed engineering transforms concepts into buildable designs.
Mechanical Design
Mechanical engineers create complete designs for:
- Custom fixtures that hold and position parts precisely
- End-of-arm tooling for robots—grippers, welding torches, vision mounts
- Structural elements—machine bases, frames, guarding
- Material handling—conveyors, lifts, transfer mechanisms
- Utility systems—pneumatics, lubrication, chip management
Modern automation uses 3D CAD software to model every component. Interference checking ensures parts fit together correctly.
Electrical Design
Electrical engineers develop:
- Electrical schematics showing all power and control wiring
- Panel layouts for control enclosures
- Pneumatic schematics for air-powered devices
- Cable routing and wire harness designs
- Component specifications and bill of materials
Designs follow relevant codes and standards including NFPA 79 for industrial machinery.
Controls Engineering
Controls engineers develop:
- PLC programs that sequence and control the machine
- HMI screens for operator interface
- Robot programs for motion and process execution
- Vision system configurations for inspection and guidance
- Safety PLC programs for safety-rated functions
Digital twin technology allows much of this development to occur in simulation before hardware exists.
Design Reviews
Multiple reviews occur throughout detailed engineering:
- Internal design reviews catch errors before release
- Customer reviews ensure the design meets requirements
- Safety reviews verify compliance with standards
- Procurement reviews confirm component availability
Phase 4: Procurement and Fabrication
With approved designs, physical construction begins.
Component Procurement
Purchasing agents and engineers source:
- Major equipment—robots, drives, PLCs
- Commercial components—sensors, pneumatics, motors
- Fabricated parts—machined components, sheet metal
- Electrical materials—wire, cable, connectors
Lead times for some components can be months, making early ordering critical.
In-House Fabrication
Many automation integrators have internal fabrication capabilities:
- CNC machining for precision components
- Welding for structural assemblies
- Sheet metal for guarding and enclosures
- Wire harness assembly
Assembly
Skilled technicians assemble the mechanical systems:
- Installing components on machine bases
- Mounting and aligning fixtures
- Installing robots and servo systems
- Running utilities—electrical, pneumatic, hydraulic
Panel Build
Electrical panels are built from schematics:
- Mounting components to backplanes
- Wiring power and control circuits
- Labeling and documentation
- Testing before installation
Phase 5: Integration and Testing
The machine comes to life as mechanical, electrical, and controls systems are integrated.
Electrical Installation
Field wiring connects:
- Panels to machine devices
- Sensors and actuators to control systems
- Safety devices to safety controllers
- Communication networks
Controls Integration
