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

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

Document current state (video)
Separate internal/external
Convert internal to external
Streamline internal setup
Streamline external setup
Standardize and train
Track and improve

Integration Points
