#TaiCaanTechnologies (www.TaiCaan.com) It brings us great pleasure to showcase our new development platform #VODBot®, a liquid handling system designed specifically for the precision sampling of human saliva. It uses precision motion control guided by a state-of-the-art machine vision system to automate specimen loading, volume measurement and sample extraction. The system provides robust, accu...

This is the first of two videos where we show how to analyse surface roughness and wear from 3D STL (point cloud) X-ray CT data. In the first part we explain the difference between 2.5D (surface) and 3D (point cloud) data then how to import, rotate, section, resample and extract the surface of interest from STL data.

In this tutorial we explain how to use autocorrelated surface generation to develop realistic surfaces, and then evaluate their 3D roughness using the S series parameters.

This is the second of two videos where we show how to analyse surface roughness and wear from 3D STL (point cloud) X-ray CT data. In this part we show how to isolate and extract the S series of roughness parameters (Sa, Sq) using 3D Gaussian Filtering to evaluate surface texture changes caused by erosive wear.

This is an study of freeform 3D surface roughness changes on a molar tooth. The tooth surface has been measured before and after exposure to fruit juice acid (citric acid) using a TaiCaan XYris optical surface profiler. The tooth is not polished before measurement to provide a more clinically relevant study of surface wear. www.taicaan.com/software/ More information on BEX software www.taicaan....

In this video the eroded volume on an electrical contact is calculated. The complexity added is the erosion is into a spherical surface. The study demonstrates how to remove the underlying "form" of the sphere and correctly calculate the volume of material lost. www.taicaan.com/software/ More information on BEX software www.taicaan.com/bex-download-form/ BEX download page

In this video we demonstrate the loading of other data formats including data from AFM (Atomic Force Microscope) measurement systems and stereolithography files (.STL) from X-CT (X-ray Computer Tomography) www.taicaan.com/software/ More information on BEX software www.taicaan.com/bex-download-form/ BEX download page

Often you will need to compare and contrast more than one surface. In this tutorial we explain how to load multiple data sets into the BEX analysis software www.taicaan.com/software/ More information on BEX software www.taicaan.com/bex-download-form/ BEX download page

In this tutorial the basic features of the imaging window are introduced and explained. www.taicaan.com/software/ More information on BEX software www.taicaan.com/bex-download-form/ BEX download page

This tutorial explores how to create video, images and data from your data for export to presentations or to other graphing software. www.taicaan.com/software/ More information on BEX software www.taicaan.com/bex-download-form/ BEX download page

This video shows how to load a data file to the Boddies Extreme (BEX) surface analysis software, and describes the function of the main windows in the software. www.taicaan.com/software/ More information on BEX software www.taicaan.com/bex-download-form/ BEX download page

Here we introduce the main 3D viewing window that displays a representation of the surface data. The tools to manipulate orientation of the display and the colour scale are shown, as well as taking 2D cross sections of the surface. www.taicaan.com/software/ More information on BEX software www.taicaan.com/bex-download-form/ BEX download page

An introduction to form fitting where surface form can be fitted and removed from data to allow the examination of the residual surface. In this example a mathematically perfect sphere is removed from surface measurement of a calibration sphere (essentially a large ball bearing with a precisely measured radius). Removing a a spherical form from the measurement reveals and the error that was pre...

We carry on from the previous video with the concept of using Gaussian filtering extract the "roughness" parameters from the surface "profile" by removing "waviness". The filter cut off length is varied and the impact on the "waviness" and "roughness" parameters is shown visually in the 2D cross section. www.taicaan.com/software/ More information on BEX software www.taicaan.com/bex-download-for...
