“Equator is designed to be an alternative to traditional dedicated gaging,” said a Renishaw spokesperson. It is more than just a new gaging system; it marks the launch of Renishaw’s first gaging product line. “The patented, low-cost design, unique in construction and method of operation, is capable of high-speed comparative gaging for inspection of high-volume manufactured parts. It has been developed and proven on the shop floor in collaboration with companies in the automotive, aerospace and medical sectors. The result is a lightweight, fast and highly repeatable gage that operators can use with ‘pushbutton’ simplicity. Equator can switch between parts in seconds, suited for flexible manufacturing processes or accepting parts frommultiple machines. “Based on an easily scaleable and adaptable ‘parallel kinematic’ structure, Equator’s patented principle allows high-speed scanning and rapid moves between features while retaining stiffness that delivers impressive point to point repeatability, critical for accurate gaging. “Installation of an Equator is possible in minutes, and an operator can switch between gaging of different parts in seconds. Reconfiguration of the gaging system to accommodate part design changes, or tomeasure new parts, is possible in a fraction of the time needed for conventional custom gaging, using industry standard DMIS programming.” Equator systems are available with two levels of software, a programmable version for production engineers to create DMIS programs and, at a lower price, a shop floor systemwhich allows those programs to be executed but prevents operators frommakingm odifications. Both software levels include MODUS Organizer operator front-end software. In the programmable version, MODUS Equator programming software allows engineers to rapidly create gaging routines for a variety of prismatic or free form. MODUS Equator features the ability to program scanning measurements and touch points, usingR enishaw SP25 compact scanningp robe. Scanning allows thousands of data points to be taken to define a feature for true form analysis. By taking the dongle provided with the programmable system and plugging it into a shop floor system, full programming functionality is activated on that shop floor system, ideal for engineers to adjust programs but also retain control, said the company. “Equator’s repeatable gaging technology is based on the traditional comparison of production parts to a reference master part,” said the spokesperson. “Re-mastering is as swift as measuring a production part and immediately compensates for any change in thermal conditions on the shop floor. Equator can be used in factorieswithwide temperature variation, simply remaster and the system is ‘rezeroed,’ ready for repeatable comparison to the master. “Master parts do not need to be expensive custom parts like a traditional gage; a production part measured on a coordinatemeasuringm achine (CMM) can establish feature variation from CAD or drawingnom inals. The results from any CMM, using any CMM programming software, can be configured to be used directly with the Equator software. “Effectively, the calibrated absolute accuracy of the CMM (often located in a temperature controlled room to ensure accuracy) can be ‘extended’ onto the shop floor to provide calibrated traceability to Equator measurements. With the calibration file loaded into the Equator software,measurementsmade in the Equator system can be referred back to the CAD or drawingnom inals. This allows true process control with SPC packages.” The Equator controller, included with every Equator system, is a dedicated control system designed to provide a secure environment for running the Equator gaging system software. It is similar to machine tool control systems, with the added ability to run Equator-specific Windows applications. Designed for Equator, it incorporates all the necessary electronic boards and software in one package. The user can create and execute DMIS measurement programs, change measurement settings and transfer data or programs. “An additional PC is not required when operating the Equator, reducing cost to the customer and eliminating the chance of incompatibility or unpredictable performance arising from thewide variation of PC architectures,” said the spokesperson. “Compared to dedicated gaging, Equator cuts fixture costs considerably. By using fixturing that positions parts to within 1 mm of where the master was measured, which has no significant effect on system repeatability, and by establishing the part orientation and datums on the part itself, the need for expensive precision fixtures is removed. “Further versatility is offered by the Equator-specific stylus changing rack (included in the purchase price of an Equator system) allowing automated in-cycle changing of SM25 stylus modules. The SM25 modules couple to the SP25 CMM probe, allowing Equator users to swap stylus configurations without re-qualifying each time. Up to six stylus combinations can be loaded into the rack at any time. These can be used on a single complex part or with multiple parts of varying geometries. “Equator can be integrated into automated cells, using the optional I/O interface to connect it to a robot, or by outputting the gage results to an SPC package. Some SPC packages also offer the ability to connect to certainmodern machine tool controls to update offset values, for true automated process control.” For more information contact: Jeff Seliga Renishaw Inc. 5277 Trillium Blvd. Hoffman Estates, IL 60192 847-286-9953 jeffrey.seliga@renishaw.com WESTEC Booth #1600
