Effective hob cutter inspections

Ingersoll knows precisely how gears get their teeth. The company specialises in vibration-free cutting tools. At its factory in Haiger, Ingersoll Werkzeuge GmbH concentrates on the design and manufacture of large-volume special tools, among them multithread hob cutters for the gearmaking industry. During production, these hob cutters undergo precise inspection with a Leitz PMM-C coordinate measuring machine from Hexagon Metrology.

The hob cutters consist of a mill base with individual cutting segments, all made of heat-treated steel. The segments have carbide-tipped indexable inserts, which can achieve high cutting speeds and metal removal rates. What makes the Haiger products so special: almost every hub cutter is treated like a one-off product and is designed for a particular machine application and machine spindle. When it comes to hob mill bases, batches of one to twelve are quite commonplace for Ingersoll.

Which also means: every hob cutter needs its own measuring program. The inspection solution from Hexagon Metrology not only takes this factor into account: "Hexagon Metrology was able to offer us a system that combined ease of programming, high accuracy and speed," says Jens Lange, QM Product and Production Optimisation at Ingersoll.

Highly accurate measurements right on the spot
The solution – a Leitz PMM-C 16.12.10 with a tactile measuring system for variable High Speed Scanning and the QUINDOS 7 software package – was placed directly beside the machining centres in the production hall. As part of a 100% inspection regime during production, the Leitz PMM-C measures various features on the mill bases and individual segments, including flatness, pocket seating and pitch to micrometre accuracy: the volumetric length measurement deviation of this coordinate measuring machine is 1.5 μm + L/600.

Brand new: measuring software for hob cutters
At the time the decision was made, no other measuring software provider offered programs that could measure . . . . .
