• Probing for machine reference.
• Multiple angular positions.
• Define rotary axis center.
• Used for multi axis machining.
• Reference ‘pad’ delta from
rotary center or pivot point.
• Used for subsequent thermal
tracking.
Automated processing– initial set up
![Page 13: Transitioning from Development to Production: Addressing ...€¦ · 05/06/2018 Slide 3 •From research lab onto the factory floor •From prototypes & tooling to series production](https://reader035.vdocuments.site/reader035/viewer/2022070709/5ebaaf00d2b1434bca0e140b/html5/thumbnails/13.jpg)
• Zero point fixture system
• Part measurement on Equator
• Complex measurements of
surfaces
• Automatic transfer to CNC
• Writing to chip / tag possible
• Adaptive machining possible
Automated processing - part set up
![Page 14: Transitioning from Development to Production: Addressing ...€¦ · 05/06/2018 Slide 3 •From research lab onto the factory floor •From prototypes & tooling to series production](https://reader035.vdocuments.site/reader035/viewer/2022070709/5ebaaf00d2b1434bca0e140b/html5/thumbnails/14.jpg)
• Set ‘ballpark’ tool offsets
• Confirm correct tool & build
• Drills, taps, reamers etc. accurately set to each other
• Reduces inspection for set up & adjustment
• Reduces potential of tool breakages
• No dynamic effects on tool or part are compensated.
Automated processing – tool setting

• Recording process output from
machined features.
• Analysis of recent parts.
• Automatic tool offset update.
• Adjusting process mean to
nominal dimension.
• Reduces measurement /
manual update time delay.
• Eliminates manual errors.
Automated processing – process control

• Verify feature size to design
intent.
• Check for distortion against
pre-machined condition.
• Analysis of surfaces against
CAD nominal.
