Introduction to co-ordinate systems

There are significant advantages of the Form Talysurf® PGI NOVUS part co-ordinate system over a traditional instrument-based co-ordinate system.

Traditionally, profilometers use a co-ordinate system based around the instrument axes. In Metrology 4.0 this is called the Instrument Co-ordinate System (ICS). Here, X, Y, and Z refer to the machine’s axes. X is the traverse unit and runs from left to right, the linear Y stage is typically mounted orthogonally and runs from front to back. A vertical columns provides the Z axis and runs up and down. This co-ordinate system represents 3D movement around the working area. It is useful for a wide range of applications and all axes can be controlled very precisely.

For the first time, the stylus tip is fully positionable around the sample, using Taylor Hobson’s unique SMART Move and Part Co-ordinate System (PCS). SMART move is very useful for providing easy access to complex features, or inside bores, for example. It removes all operator guess work and gives confidence to the operator.
