Coordinate System

There are two kinds of coordinate system in the image measurement: the machine coordinate system and the workpiece coordinate system, which are all right handed Descartes Cartesian coordinate system。

1. Definition of the coordinate system

Machine coordinate system: The origin of the machine coordinate system is a fixed point relative to the machine worktable. When the three motion axes stop at the origin position, the machine coordinate origin and the detection center of the image measuring instrument coincide with each other. The machine coordinate system is the measuring datum. It is fixed and can not be changed.

Workpiece coordinate system: The origin of the workpiece coordinate system is a datum point on the workpiece. You can arbitrarily create or change the workpiece coordinate system as required。

2. Creating coordinate system

(1) Establishing the machine coordinate system (Go Home)

   The machine coordinate system is inherent, you does not need to create the machine coordinate system. It will prompt to find the Home Position as follows when the software is opened. The machine coordinate system is automatically established after the Home Position was found.(Note: Here finding the Home Position is to find the origin of the machine coordinate system)
