Coordinate System

Next, double-click on the ‘Coordinate System’ node under the ‘Control Description’ node and select the ‘Planes’ tab. These settings contain all the information related to the interpolation planes supported by the machine.

We want our machine to support the XY-plane (G17), the ZX-plane (G18) and the YZ-plane (G19). We will not select a default plane as we want our post-processor to generate the required plane code when it outputs the code for the first operation. Next, select the ‘Translation’ tab. Leave the Local coordinate – tanslation available checkbox unchecked. Using Local Coordinate Systems (LCS) is typically only done with multi-axis CNC machine tools. Since our post-processor is for a 3-axis machining center, Local Coordinate Systems aren’t needed or supported. Next, select the ‘Rotation’ tab. Leave the Local coordinate – rotation available checkbox unchecked. Using Local Coordinate Systems (LCS) is typically only done with Multi-Axis CNC Machine Tools. Since our post-processor is for a 3-axis machining center, Local Coordinate Systems aren’t needed or supported. Next, select the ‘Advanced’ tab. Leave the Scaling & Mirror checkboxs unchecked. Since our post-processor is for a 3-axis machining center, Local Coordinate Systems aren’t needed or supported. Make sure to review what is displayed when you allow the cursor to hover over a specific input field or control as well as what is in the information area at the bottom of the interface as you move through the various input fields and controls.
