Understanding Cycle Time – A Simple & Practical Explanation

Cycle Time is a critical performance metric in manufacturing and operations. It tells us how long it takes to produce one unit at a workstation and directly impacts productivity, capacity planning, and delivery performance.

Cycle Time Formula:  Cycle Time (per unit) = Total process time / Total units produced

Example from the image:
-  A CNC machine produces 90 units in 1 hour (60 minutes)
-  Cycle Time = 60 / 90
-  CT = 0.67 minutes ≈ 40 seconds per unit

This means the machine completes one finished part every 40 seconds under stable conditions.

Why Cycle Time Matters:
• Helps identify bottlenecks
• Improves line balancing
• Supports OEE & productivity improvement
• Essential for lean manufacturing & continuous improvement
