Changeover Optimizer

Overview

The Changeover Optimizer skill provides comprehensive capabilities for reducing setup and changeover times. It supports SMED (Single-Minute Exchange of Die) methodology, sequence optimization, and changeover time tracking.

Capabilities

• Internal/external setup separation
• Changeover video analysis
• Parallel task identification
• Standardization opportunities
• Quick-release mechanisms
• Sequence optimization
• Changeover matrix
• Time reduction tracking

Used By Processes

• LEAN-004: Kanban System Design
• CAP-002: Production Scheduling Optimization
• LEAN-003: Kaizen Event Facilitation

Tools and Libraries

• Video analysis tools
• SMED templates
• Time study software
• Scheduling optimization

SMED Methodology

Stage 1: Separate Internal and External Setup

| Type | Definition | Goal |

|------|------------|------|

| Internal | Must stop machine | Minimize |

| External | Machine running | Maximize |

Stage 2: Convert Internal to External

• Pre-stage tools and materials
• Pre-heat/pre-cool components
• Prepare documentation
• Pre-adjust settings

Stage 3: Streamline All Operations

• Parallel tasks (multiple operators)
• Eliminate adjustments
• Standardize procedures
• Use quick-release mechanisms

Changeover Analysis

Current State:
- Total time: 120 minutes
- Internal: 100 minutes
- External: 20 minutes

Improvement Opportunities:
1. Move mold retrieval to external: -20 min
2. Pre-heat mold: -10 min
3. Use quick-clamps: -15 min
4. Parallel connection work: -10 min
5. Eliminate test shots: -15 min

Target State:
- Total time: 30 minutes
- Internal: 25 minutes
- External: 35 minutes

Changeover Matrix

| From / To | Product A | Product B | Product C |

|-----------|-----------|-----------|-----------|

| Product A | - | 30 min | 45 min |

| Product B | 35 min | - | 25 min |

| Product C | 40 min | 30 min | - |

Quick Changeover Techniques

| Technique | Application |

|-----------|-------------|

| Quick-release clamps | Replace bolts |

| Intermediate jigs | Pre-positioned tooling |

| Color coding | Visual identification |

| One-turn fasteners | Reduce turns required |

| Standardized heights | Eliminate adjustments |

| Preset gauges | Eliminate measurement |

Implementation Steps

1. Document current state (video)
2. Separate internal/external
3. Convert internal to external
4. Streamline internal setup
5. Streamline external setup
6. Standardize and train
7. Track and improve

Integration Points

• Production scheduling systems
• Video analysis tools
• Training platforms
• OEE tracking systems
