Flatness Measurement of HP Turbine Shell June 6, 2011 Tags: flatness measurement, hp turbine shell, surface flatness Recently, a flatness measurement was needed on two halves of an HP turbine shell using LEVALIGN system. The top half (resting upside down) was a typical quick and easy measurement, as shown below in Figure 1: Figure 1 The second half, was not so typical. The studs had to remain in the shell and the customer wondered if our tool could still take the measurement with the lineofsight obstructions for the laser from the studs. The answer was YES! The unique “InfiniSplice” feature of the LEVALIGN allowed for this to happen without having to resort to custom brackets to shoot over the top of the studs. InfiniSplice allows for multiple sets of measurements to be combined into one unified measurement. This is based on the concept that two sets of measurements can be unified or merged if they have three or more points measured in common. It’s simple. Just measure as many points as you can with the LEVALIGN laser emitter in the first position. See Figure 2. Figure 2 Then move the laser to another position and measure any points you couldn’t measure with the first measurement setup plus at least three points that you did measure with the previous RSS Feed Youtube Twitter Facebook Flickr Connect Calendar April 2015 M T W T F S S « Mar 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 Categories Alignment Articles and Case Studies Balancing Condition Monitoring Geometric Measurement Industry Events Lubrication LUDECA News Maintenance Tips PDM RCM Reliability Training Ultrasound Vibration Analysis Archives April 2015 March 2015 February 2015 January 2015 December 2014 November 2014 October 2014 September 2014 August 2014 Search
