4D Technology to host surface defect measurement webinar on July 18

4D Technology Corp., Tucson, Ariz., will host the "Improving Surface Defect Measurement: Solutions and Case Studies" webinar on July 18, 2017, from 12:00 p.m. to 1:00 p.m. EDT. To register, visit https://attendee.gotowebinar.com/register/611815932310945537.

Accurate measurement of surface defects is essential to the long life and performance of precision components for aerospace and automotive applications. The challenge facing inspectors is how to quantify pits, scratches, and bumps with sufficient resolution, coverage, and speed to satisfy customer requirements—particularly on complex surfaces or on large components. This webinar will cover the challenges involved in making accurate surface defect measurements on precision machined surfaces.

Kevin Harding, president of Optical Metrology Solutions, will discuss the strengths and shortcomings of common measurement techniques, from assessing surface defects with a “calibrated fingernail” to employing high-end 3-D surface profilers. Dr. Erik Novak of 4D Technology Corp. will present the InSpec® surface gauge, a hand-held instrument for noncontact, 3-D measurement of surface features and defects.
