Combining the scanning capabilities of the REVO® 5-axis system with MODUS™ Blade planner software, SurfitBlade™ and MODUS metrology software breaks through the limitations of standard blade measurement techniques.
Traditional methods of blade inspection are limited to a number of cross sections. However, REVO's sweep scanning techniques and Renishaw's Blade Toolkit software enable the accurate and fast measurement and evaluation of the whole blade.
Now, it is possible to carry out an unlimited number of sections or full surface analysis from high precision tactile probing data.
To initiate the blade measurement process, MODUS Blade planner software automatically generates a collision-free sweep scan program for REVO. This program is then run on the CMM using MODUS metrology software.
The sweep scan operation produces an accurate ‘point cloud' encompassing the entire airfoil surface. Using MODUS point cloud sectioning functionality, it is possible to generate sections wherever they are required.
As the complete data set is stored, additional sections can be created without having to re-measure, should the need arise.
The data obtained can then be processed in two ways:
The data is sectioned by MODUS and compared to the nominal CAD model requirements. The analysis results are presented through MODUS reporter, which also produces a defined PDF document for archiving.
The data is processed by SurfitBlade to produce a full NURBS surface for use in aerodynamic and stress analysis, etc.
