This feature almost eliminates the need to have an expensive computer aided
manufacturing (CAM) system for 2-1/2 axis applications. Import a .dxf file from
your computer aided design (CAD) system and NCPlot will create a CNC program to
machine the imported shape! For contours, NCPlot even helps you create a G code
program that considers the cutter size. Using the Get Offset Data
function of NCPlot (shown below), you can create motion commands based upon a
specified cutter's centerline path.
Import DXF drawings to quickly create G-Code for both Mill and Lathe
Any tool path plot can be saved as a DXF drawing file for loading back into
a CAD or CAM system
Get offset data: After importing a .DXF file from your computer aided
design (CAD) system, this feature is helpful in creating a tool path based upon
the cutter's actual size. It is also helpful in creating roughing passes from a
finished contour pass. After selecting the entities you wish to offset (we've
selected the milled contour), select Offset from the Calc menu.
You'll be asked the amount by which you want to offset (the cutter's radius).
See next image for what happens next.
Get offset data (continued): NCPlot will create a new set of geometry
and will allow you to create the G code to move through the modified tool path.
See next image for what comes next.
Get offset data (continued): Click the Convert Selected to G
Code selection from the Tools menu to create the G code to machine
the selected entities. You'll be asked to fill in some information, including Z
axis positions and feedrates. Note that you can even have NCPlot generate
multiple Z passes!
