Why accurate tool measurement?
Reduce tool tolerances
• Save material by reducing wall thickness
Avoid problems in can forming
• Less downtimes
• Greater Yield
• No tool related crashs
Shorter set-up times
• Shorter downtimes
Longer tool lifetime

Comparable functions to RINGMASTER and PUNCHMASTER
4. RICOS – Ring Profile Gauge
02.11.2018 www.oeggmbh.com 23
Purpose
Measurement of inside ring profile
Measuring system
• mechanical tracer
• often seen in toolrooms!
Advantage of RICOS
• protection of stylus needle
• exact positioning of the ironing die
RICOS: Software
Purpose
• Creation of form- and tolerance models according CAD-drawing of the ironing die
Advantage
• comparison with the tolerances
• fast good / bad decision
02.11.2018 www.oeggmbh.com 24
Tolerance model development software
RICOS: Examples
02.11.2018 www.oeggmbh.com 25
RICOS: Measuring process
The RICOS mechanical setup ensures, that the ring is
• positioned exactly
• and reproducible
• in the scan range of the tracer
This is the requirement to:
• compare the results
• compare the results with the model
