Resources

PEC Labs & Equipment

At the heart of the Precision Engineering Consortium’s facility are four temperature-controlled, vibration-isolated laboratories in which faculty, students, and staff develop new ideas for metrology, precision fabrication, and control. The laboratories (temperature controlled at 20 degree C to ±0.03 degree C) are equipped with the most advanced measurement, computational, and fabrication resources worth over $2 million.

Services

The Precision Engineering Consortium’s computer scientists, physicists, and engineers form a unique multidisciplinary team. These researchers have an impressive array of resources at their disposal in our facility as well as access to the resources of the entire university via collaboration with other laboratories and other faculty. The PEC research team can provide engineering consultation, prototype fabrication and state-of-the-art metrology services to industrial and research communities. This includes services to other on-campus research groups. For more information, please contact Jacob Marx (jcmarx@ncsu.edu) at (919) 515-3977.

Fabrication Facilities

The PEC has purchased or built laboratory-scale and production-scale diamond turning machines (Pneumo ASG2500 and Nano Form 600), precision grinders, and a computer-controlled focused ion beam machining system. Custom controllers have been developed and integrated in these machines tools to improve and expand their performance.
