Five Axis Vision Inspection

Meyer Tool, Inc. utilizes Five Axis Vision Inspection Systems for a variety of non-contact dimensional inspections. Designed and built to support MTI's own production, the system has a proven track record for providing accurate and precise measurements on line-of-sight, machined characteristics.

The Five Axis Vision Inspection system is ideal for measuring the position of cooling holes and slots, as well as inspecting diffuser footprints, notches, and diameters. The variable data feeds directly into the Orion SPC data management package for real-time and off-line analysis.

Meyer Tool created the system to address a key problem facing the industry: How best to accurately obtain positional measurements for small diameter cooling holes on airfoils. Many competitors and customers use CMMs or manual layouts to verify the true position of these holes. Both methods rely on a small pin that flexes and bends and can result in false readings. Meyer's Five Axis Vision Inspection System successfully passes Gauge R&R studies for hole positions held as tight as .010" - .020".

Vision Vision Machine Accuracy:

  • Linear Axis Positioning: ±.001" per foot
  • Rotary Axis Positioning: ±30 seconds
  • Linear Axis Repeatability: ±.0005"
  • Rotary Axis Repeatability: ±15 seconds

The system is controlled by Meyer Tool Inc's proprietary software with programs generated from the CAD model. The machine measures the difference between the nominal position and the deviation in X and Y from nominal at the center of the hole.

The Five Axis Vision Inspection System also works like a surface light comparator allowing a variety of characteristics to be measured, stored and analyzed. Screen capture images can be generated as documentation to support an inspection result.

The system is Meyer Tool, Inc's answer to fast, accurate and precise non-contact inspection for gas turbine components.

eCAD Comparator

Recently, Meyer Tool began working with C.C.P. and their new eCad system which combines networked CAD data with a state-of-the-art CNC visual comparator. The eCad system links the CAD data to the product or consumable being inspected, showing the tolerance bands. Variable and attribute measurements are acquired through the system and managed via the Orion SPC network.
