Standard Machine Overview

100% inline dimensional and geometrical inspection
30-60 second cycle time (Cycle Time increases as the Diameter of the gear increases)
<1µm Repeatability
Inspect gears < 250mm Diameter.

*Larger gears CAN be inspected with an upgraded machine for additional price. (requires additional mechanical design)

Allen Bradley PLC – Easy integration with Customer line and Plant Data System
10 Minute Part Changeover
AGMA, ISO, and DIN standards for accuracy grading.
Laser Profile Sensors calibrated to a common coordinate volume
Rotary Air Bearing <20nm runout
+V3D Core Software – Calibrates Sensors into a common coordinate system and generates point cloud
Metrolog Inspection Software – Pulls in point cloud, compares to CAD model and generates results
+V3D Comm – Primary control software that synchronizes the rotary motion with the sensors, directs data traffic and

communicates status to PLC

Additional Part Types

The machine is designed with interchangeable tooling plates for

different parts.

Part type changeover is a 10-minute process:
1. Remove sensors
2. Replace Tooling Plate
3. Replace sensors
4. Calibrate sensors
5. Ready to run
Additional Part type cost includes:
Metrolog Inspection Software Programming
Sensor Position and Tooling Plate design
Calibration of gage (Artifact Design and Certification)

Lab Qualification

Prior to accepting a PO, we will verify feasibility using our lab system to make sure the sensors collect reliable data from the surface of the gear flanks. Our lab system is also used to determine the

ptimal sensor locations to implement in the

mechanical design of the final machine. Upon request a correlation study can be done before ordering a machine, we need to manufacture and certify an artifact to calibrate the sensors, program an inspection in Metrolog, and run a study.

Create Gear Model

We will utilize a Gear Module to create a CADModel for the inspections. A provided model is not sufficient to perform inspection in Metrolog. The Model must be created within the software with information from the part print. The Gear Module has Pitch information as well as Helix and Profile locations built into its generated Model. *Bevel Gears still need development 10/17/19

Measurement Method

Metrolog inspection software aligns the Cloud of points measured to the generated CAD model using predefined datum surfaces. Cylindrical regions of interest are established along the profile and helix to compare the data points with respect to the nominal CAD surface. We can measure at multiple diameters and levels.
