Automated Optical Measuring System for Dimensional Testing of Turned Parts

Mahr Federal Inc. (Providence, RI) will feature their new, totally redesigned version of the MarShaft™ Scope, a high-precision, fully automatic optical measuring system for dimensional testing of turned parts. The new MarShaft Scope Plus is now twice as accurate as previous — and competitive — models. It offers micron level measurements, and includes a new MarWin®-based controller and system architecture that opens new levels of machine capability.

The new MarShaft Scope Plus also incorporates new EasyShaft™ operating software that facilitates easy and quick measurements. The optional ProfessionalShaft™ software high-level script programming allows virtually unlimited customizing capability for these systems.

“The goal of this ground-up redesign was to apply Mahr’s extensive experience in form, surface, and contour measurement to the world of optical shaft measurement and fundamentally change what is possible,” said Pat Nugent, the vice president for Mahr metrology systems. “In addition to mechanical enhancements that improve accuracy, we’re now using the same electronics and controller architecture, and the same MarWin operating platform, as our high-end form testers.”

The error limit for measuring length and diameter with the new MarShaft Scope Plus is (2+L/125) µm. “This groundbreaking level of accuracy for an optical shaft measuring system allows high precision measurements on turned parts that typically couldn’t be measured by these types of systems,” said Nugent.

Operational software for the MarShaft Scope Plus comes in two levels: basic and professional. Basic EasyShaft software provides simple touch screen operation utilizing selectable feature icons, many of which are easily recognizable from the standard Feature Control Frames that the user sees on their part drawings. ProfessionalShaft script-level programming of the new MarShaft Scope Plus allows expert users virtually unlimited access to the machine’s capabilities.

All MarShaft Scope Plus systems are equipped with touch screens with intelligent multi-touch gestures built in, so zooming in on specific features is as easy as the two finger “pinch to zoom” we all know from typical tablets. Moving the camera view around the machine is done by a flick of the finger on the screen just as you would do to scroll up or down on a tablet.

A full range of other Mahr Federal handheld gages and other dimensional metrology products will also be on display. [email protected], www.mahr.com
