p The entire W10 package can be readily ftted into a case smaller than a briefcase. It combines portability with precision. p The Jenoptik W10 is designed to be used on the production line or in a machining cell. The measuring unit is brought to the part, not vice versa, yet the measurement capability is lab-like. On-Site Surface Roughness Measurement While surface roughness measurements can be critical in production operations, one of the problems associated with making those measurements is that the parts are being made in the machining line while the measurements are made in the metrology lab. Which isn't always convenient. Or timely. The traverse unit, which handles the probe, is ergonomically designed to ft into a user's hand. It is approximately the size of a telephone handset (151 x 50 x 55 mm). And the base unit, which includes a color touch screen and optional printer, is about the size of a business telephone base unit (224 x 226 x 70 mm). It weighs just 275 g (9.7 oz). Jenoptik (jenoptik.com/industrialmetrology) has developed the W10, a portable surface roughness measuring system that's capable of checking more than 40 roughness and waviness parameters as it can be ftted with an array of probes and accessories. The W10 can track eight separate measurement programs, up to 100 separate profles, and ofers a total storage capacity of up to 10,000 completed measurements. The lithiumion battery in the traverse unit is capable of making more than 800 measurements per charge. The device is designed so that it can measure perpendicular to the part, traverse to it, or overhead. There is a support prism that precisely locates or shafts from 10 mm in diameter, and which also serves to protect the inductive skid probe in measuring bores from 12 mm in diameter. There are built-in, extendable tripod legs that allow the device to be mounted on a surface. The W10 has a measurement range/ resolution of 320 µm. The maximum traverse length is 17.5 mm. Comparing the Actual to the Digital Heidenhain (heidenhain.us) has developed a new software system that provides the means to measure and determine parts profles within tolerance zones, with an optional capability to comparing the measured part with a 3D model. The IK 5000 QUADRA-CHEK PC software system can be used with new coordinate measuring machines or retroftted for existing equipment. To use the optional 3-D Profling system, a 3D model is sent to the PC running QUADRA-CHEK with IGES or STEP. Then the part is measured. The system fts and compares the digital and actual model within the IK5000, such that the overall profle and individual point results can be tolerance, printed, and exported as required. p IK 5000 is PC-based inspection software that can be used for 2D and 3D measuring tasks. Its optional 3-D Profling feature allows comparison of the measured part with the CAD model in the PC. 41
