Comparison of 3D measurement with reference dataset of involute toothing (radius 1.2mm).
Global supplier of optical 3D surface management solutions, Alicona has released a new MicroGear measurement module aimed specifically for the measurement of micro gears up to 5mm diameter.
Developed in conjunction with German gear and spline specialist Frenco and using Alicona’s FocusVariation technology, this new measurement module provides optical non-contact measurement on gears that are typically difficult to measure. The process of measurement captures the full 3D form of a micro gear wheel and it is on this 3D model that measurements are made.
Micro gears present a challenge in terms of measurement as tactile systems can only provide data from a single line scan in each direction on the helix or spur. The amount of data collected can also very limited using traditional systems due to the small features, which can be difficult to capture.
Tactile and Optical Comparison.
The new optical measuring solution captures the full form of the gear teeth using area-based measurement rather than a line based measurement, resulting in more robust and accurate data.
A complete measurement of every tooth is possible within a range of 0.1mm Ø to 5mm Ø with unlimited numbers of teeth measurable. The measurement process can fast produce high resolution and repeatable results to VDI/VDE standards.
CAD dataset comparison is also possible to show the differences between the actual produced products in relation to the design requirements with the capability to set up tolerance ranges.
A complete range of parameters are available and include profile angle deviation, profile form deviation, total profile deviation, helix angle deviation, helix form deviation, total helix deviation, individual pitch deviation, total pitch deviation, runout deviation and more.
This software is useable with the Alicona InfiniteFocus G5 with advanced real3D rotation unit.
