Problem & Context
A precision machine shop noticed certain CNC programs were always running late. Spring passes (rework without a change in toolpath) were silently adding time, without being tracked.
Using JITbase, they identified that 51% of overtime came from these reworks. With data in hand, they finally understood the true cause of the delays
From Hidden Losses to Real Performance Gains
Once JITbase flagged the repeated spring passes, the Methods department validated the issue and improved the CNC programs accordingly.
The impact:
+50% performance improvement on affected programs
+15% overall OEE increase
Better planning with more reliable production estimates

This case study reveals how program-level monitoring helped one shop align real and estimated cycle times, eliminating hidden time losses.
