traditional concept of 100% hard gaging disappeared along with production runs in the millions. “Part runs [today] are in the 100,000s even in automotive. Some companies are configuring flexible production setups to run multiple engine

The Truth Is: A probe may be an effective way to verify tool lengths between cuts, but it is not the most efficient way to set your tools. A “guess-and-check” process for making adjustments wastes valuable cutting time. A Speroni MAGIS Tool Presetter can verify runout, measure length, diameter, radius, and other geometries using measuring icons, and it can also inspect tools for wear. Spend less time adjusting and more time cutting.
The notch-free nut design of our Mega Micro Chuck prevents vibratio at high sp ed for superior balance and concentricity. It not only eliminates whistling noise and coolant splattering, but also assures increased strength of the nut itself. The super slim taper design of the body offers added strength for micro end milling, and reduces interference in long reach applications.

These are designed to measure long, round workpieces such as crankshafts, camshafts and driveshafts, directly on the production floor. An LED light source illuminates a shaft rotating on a fixture. A high-resolution CCD line sensor captures a silhouetted shadow, digitally measuring the contour as the piece rotates. Models in this line measure parts as small as fuel injector nozzles or medical needles and as large as 2500-mm aircraft engine shafts. Programmers use a teach-in method to create parts programs. They call up programs when needed and workpieces are measured in seconds.
components on the same line: a 6-cylinder crank one week, a 5-cylinder the next day, and a 4-cylinder the next,” agrees Andreas Blind, vice president of Hommel-Etamic (Rochester Hills, MI). Flexible, reconfigurable metrology is the demand of the future. Hard gages and fixture gages are still very useful, he explains, but today they may be built to work in conjunction with flexible solutions or with retooling and reconfiguration in mind. There remain tradeoffs between speed, flexibility and cost. “This does not mean hard gaging fixtures go away,” he explains. “It does mean you build them with more flexibility, so that you can retool them very quickly.” The company uses three basic kinds of technologies for metrology: pneumatic, tactile and optical. Each is integrated into flexible or dedicated gaging solutions, depending on a customer’s budget and expecta- tions towards flexibility. At the same time, companies like Hommel-Etamic are expanding off- he-shelf production metrology. A good
