Understanding the workpiece coordinate system in CNC Milling and calculating coordinates
Introduction
Milling is used to create geometrically complex parts. Understanding the coordinate system is the key to get the right toolpath for your operations.
- Watch the video to get the simple idea of the tool movement compared to the position of the workpiece
Analyze the X,Y and Z axis
Understand the position of the axises
Coordinate system on the workpiece
If you were to change the placement of the coordinate system on the workpiece, how would that affect the current cordinates, how would you recalculate them?
Workpiece center coordinate system
If you were to put the coordinate system in the center of the workpiece, you'd divide X and Y axis into 4 quadrants.
Analyze the photo to understand the center coordinate system
Coordinate system
Analyze the photo and define the coordinates of the shown points on x and y axis
Coordinate table
After defining the coordinates on the photo shown before, it is always good to make a table of the cordinates. Since the task was to define coordinates of the points shown on the X and Y axis, we will say that the Z cordinate is 0 because it is not defined.

Answer all the questions correctly
Exercise
Define the cordinates of the points shown in the task. Only X and Y axis
*There must be no spaces between points while entering the answer
*Example : "A(x,y)B(x,y)C(x,y)D(x,y)"
*Left click on the little photo to upscale it.
