4. Eliminate coolant pipe setting
Varies from application to application but when operators are
setting the coolant pipe direction it normally takes 2 to 3
attempts to get it right – red light on!
Poor chip control often then knocks the pipe and so setting is
quite a regular occurrence.

5. Quicker production start up
By eliminating either ‘first test component’ or ‘measuring cuts’
the production rate is increased and scrap reduced. The best
analogy is the pit stop in motor racing. Calculated through the
year if quick change was used the number of additional
components produced and reduced scrap rate is significant.

First test component – higher volume production - The first
component of every tool change is often scrapped and the tool
change time needs to be considered as:
- change tool (keep old offset)
- cut complete part
- measure finished component
- adjust offset

Measuring cuts – low/medium volume production – Taking a
measuring cut with backed off offset ensures that the
component is not scrapped but can take longer time. Tool
change time needs to be considered as:
- change tool
- back off offset
- cut
- measure
- adjust offset
