Dock in the House
Gear manufacturers can use this device in the measuring lab when it is docked, and also on the shop floor as a portable system when onboard inspection isn’t available.
The PM 750 from R&P Metrology is a portable device used to measure large parts on production machines lacking onboard inspection. A docking system with a rotary table is also available.
It’s always good to have options, and that’s what the PM line of gear inspection and measurement systems from R&P Metrology provides. Designed as a portable device, it is used to measure large parts on production machines lacking onboard inspection. It allows for inspection to be conducted on many different machines with a single measurement unit that is easy to transport between locations. In addition, a new docking station with a base plate and rotary table transforms the device into a standalone, full-featured, four-axis (+1 positioning) measurement system that is capable of profile and form measurements as well as gear inspection and 3D measurements.
The PM is a three-axis CNC measuring column, capable of gear inspection, form and profile measurements as well as 3D measurements. The system utilizes proven air bearing and linear motor technologies and industry standard 3D scanning probe systems from Renishaw. The standard models are the PM 750 and the PM 1250. The PM 1250EX (extended version) is also available for larger gears, as well as custom configurations.
R&P Metrology designs and builds its own metrology equipment concentrating on medium and large parallel axis gears, bevel gears, tools, shafts, bearing rings and 3D parts. It is represented in the United States by Kapp Technologies, which also provides support, service and sales throughout North America. Watch a video of the system in action.
Guidelines used to standardize the measuring process can provide a good basis for making gage decisions.
Virtually every machine tool builder lists, as part of a machine's specification, accuracy and repeatability figures. What's generally not given is the method used to arrive at the figures. Though these methods are defined in linear positioning standards, not all builders use the same standards.
A laser scanning system helps this shop capture the free-form surfaces on a hand-sculpted original. The resulting digitized models are the basis for CAM applications such as programming a CNC machining center.
