Summary Gauge R&R Gauge R&R

URP 40-100: Conclusion

Cost effective solution for measurement of rings and punches in beverage can manufacture

But

• Little less accurate than Ringmaster and Punchmaster

• Little less comfortable handling

• No automatic roundness measurement


Comparable functions to RINGMASTER and PUNCHMASTER

4. RICOS – Ring Profile Gauge


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


Tolerance model development software

RICOS: Examples


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

Current Development Project

- Optical Ring Profile Measuring System


5. Ring and Punch Inspector


Inspection of both rings

and punches

• with or without camera

available

• useful help in the toolroom

OEG-Toolroom: We think like Canmakers

• Solutions for the perfect toolroom in 2 piece can manufacture

• specially developed for can industry

• developed in close cooperation with can makers

• currently 75 can plants worldwide proves our competence
