Tech Tuesday is a weekly blog that addresses some of the most common questions and concerns that I hear throughout the previous week from users of BobCAD’s CNC software. Both customers and future customers are more than welcome to leave a comment on what they would like to see covered for the following Tech Tuesday. If you missed last week’s Tech Tuesday, click here.

Plane Handling – Arcs

The standard planes for CNC machine tools that follow the Right-Hand Rule are:
· G17 (XY Plane)
· G18 (XZ Plane)
· G19 (YZ Plane)
 
Following standard convention, you view a plane by looking down the vector of the plane from the positive side looking at the origin.

To explain that in more detail, look at the image above. If we are looking at the G18 plane, we would look at that plane from the Y+ coordinate looking to the origin. The result of this has us looking at the back face of a standard cube. When looking at the G19 plane, you are looking from the X+ coordinate looking to the origin which has us looking at the right face of a standard cube. For standard CNC controllers that follow the Right-Hand Rule, you determine the arc direction of G2 (CW) and G3 (CCW) by looking from the top (G17), back (G18), and right (G19) views.

Alternate Views

When looking at views that are opposite of the plane it is important to understand the arc directions are reversed.

That’s all we have for today’s topic on understanding plane & arc movements. Hopefully, this has shed some clarity on how your machine intends to move before you cut! Thank you again for reading another Tech Tuesday; see you next week!

    I’m using bobcadcam Trail software best software easy to use

  2. James Siemer says:

    Thanks for doing some lessons that are NOT version specific. I am still using V25 which is fine for me……………

    • Mike Downss says:

      V25 is a good version but have you had a chance to try the V31 demo? I think you will be pleased with the changes we have made since V25.
