IMTS Pavilion: Quality Assurance Miniature Noncontact Encoder
With a readhead as small as 6.7 × 12.7 × 20.5 mm, Atom is the world’s first miniature noncontact optical linear and rotary incremental encoder to use filtering optics with Auto Gain Control and Auto Offset Control for exceptional signal stabil- ity and dirt immunity. Applications include laser scanning, precision
micro stages, semiconduc- tor, medical, DDR motors, microscopy, scientific
research and
space-critical motion control, inspection and metrology. The system features low Sub-Divisional Error (SDE), low jitter and long-term reliability. Atom offers analog speeds to 20 m/s (29,000 rpm on a 17-mm disk) and digital resolutions to 1 nm when used with Renishaw interpolation electronics. The readhead includes a setup LED to allow quick and easy instal- lation, and an autocalibration routine to enable faster optimi- zation. Scale options include linear and rotary (angle) scales in stainless steel and glass. Renishaw Inc. Ph: 847-286-9953 Web site:

The 700 Series is very useful in checking EDM or laser-drilled holes, found in aerospace or power-gen turbine components, for example. For both round and shaped holes, the system verifies precise hole presence and accurately measures hole location. Available in a high-resolution 20× magnification, the system features a 38" (965-mm) diagonal image viewing area. Methods Machine Tools Inc. Ph: 978-443-5388

CMM
The latest generation of the Zeiss Contura is even more precise than its predeces- sor and offers a large pack- age of optical sensors on top of additional measuring ranges as well as outstand- ing scanning technol- ogy, Zeiss Calypso 2014 software and a highly tuned overall system. Another new feature is the range of measuring volumes. The Zeiss Contura family has
eight different sizes starting with a measuring volume of 700 × 700 × 600 mm up to 1200 × 2400 × 1000 mm. Thanks to its robust design, Zeiss Contura can also be used near produc- tion. The latest and most powerful Zeiss scanning sensors are available for the machine. Zeiss Industrial Metrology Ph: 800-327-9735

Roughness Gage
The TC64-RG was developed for those who want to check part sur- face finish before removing the part from the CNC machining center. With a special stylus and the gage’s integrated Digilog-technology, which allows analog scanning of the part, the gage can accurately determine a part’s surface “rough-
