Calibration Services for Coordinate Measuring Machines
Select Calibration Incorporated (SCI) is a third party service provider specializing in calibration of coordinate measuring machines. The technical manager and principal architect of SCI has worked with CMM's since 1990 in nearly all areas of coordinate inspection but primarily around service, retrofitting, and calibration.
SCI is able to read and write numerous compensation error map formats. The supported formats include AAt3D (.TXT, *.BIN), Apogee (.RES), ASI (.DAT), Brown and Sharpe CT1 and CT2 in various encodings (.DAT, .CMP, .ASC, .BIN, .ENC), Chorus (.DAT), DEA maps in various formats (.DAT), CMM Manager (.TXT), DEVA (.NOB, .TXT), Leitz (.TXT), LK (ERRC), Metrolog (.RES), OpenDMIS (.TXT, .BIN, .ECD), Renishaw (.GEC .GECS, 3PG), Sheffield (.CFG .SMP), Verisurf (.V3D), Virtual DMIS (.TXT), Wenzel (.V02), and Zeiss (.DAT, Yxxx). This includes the ability to read and write compensation error map files to certain controllers (Hexagon: FBPC, FB2, B3C-LC, FDC, Sheffield: MP35, SMP350, UMP360, UMP370, SMP400, and Zeiss: C99).
The method SCI uses to calibrate machines involves a semi-automatic measurement routine with unique equipment and software that produces a complete error map in a very predicable amount of time even if machine has only a partial or completely empty compensation error map table. A clear benefit of this approach is that the machine is always as good as it could be following the calibration excluding any mechanical or environmental issues. Another benefit is the ability to monitor of all changes that occur in a machine between calibration intervals.
The inspection software is an important part of the calibration process due to the need for specific information from the different measurement sequences. The part programs used are as simple as possible relying on external software to process the measurement data. Currently SCI supports inspection software that can run programs written in native DMIS such as LK Camio and OpenDMIS and some proprietary software languages such as PC-DMIS and Tutor for Windows. Adapting to new inspection software is possible by writing appropriate part programs that output the required information.
SCI invests a considerable amount of time developing software tools and distributes many of these through the website. Utilities available include the ability to simulate measurement errors on a CMM, tools to explore how compensation error map data is applied when using a CMM, tools to convert raw laser data into a suitable format, and various editors intended to solve problems that have been encountered in the field. SCI also has a number of articles on various topics related to CMM's.
CMM Services Inc.
Calibration: Regular calibrations ensure accuracy. A CMM should also be calibrated after a move, certain type of repairs, a major crash or when measured results are suspect.
Repair: If you are tired of 5-10 day response time from your CMM manufacturer, give us a call. We will be right there. Most phone calls returned within 4 hours and on site within 2 working days.
Relocation: With many years of experience moving and installing CMM’s, we can be counted on to safely move your equipment.
