Select the paths you want to work with.
Open the toolpaths tab on the right side of the screen and press the "Profile" button.
Set the Start Depth. Zero corresponds to the top of the material and is usually where you want to start cutting.
Set the Cut Depth. This is measured RELATIVE to the start depth. For example, a start depth of 0.5 and a cut depth of 0.6 would end up cutting to a final depth of 1.1.
Select the appropriate Tool. There are many cutting tools pre-defined in the Tool Database. Press the "Select" button to access them and choose one. DO NOT EDIT ANY OF THE TOOL PRESETS WITHOUT STAFF APPROVAL. You can damage the tool, the machine or hurt someone if you enter inappropriate speed and feed settings.
Choose whether to cut OUTSIDE, INSIDE or ON the specified path(s). Then, press "Calculate" to generate a toolpath with the specified depths, cutting tool and cutting parameters.
OUTSIDE will offset the cut path by the radius of the cutting tool towards the exterior of an enclosed area. The cut path is shown below as a solid pink line with arrowheads and the selected path defining the part is shown as a dotted line. Notice the offset. This ensures that the edge of the cutting tool follows the perimeter of the part.
INSIDE will offset the cut path by the radius of the cutting tool towards the interior of an enclosed area. The cut path is shown below as a solid pink line with arrowheads and the selected path defining the part is shown as a dotted line. Inside cut paths are typically used for cutting holes rather than releasing parts.
ON will place the center of the cutting tool directly over the selected path. Remember that you will lose material on either side of the path equal to the radius of the cutting tool.
Selecting the "Ramp Plunge Moves" option will ease the cutting tool into the material by zig-zagging vertically rather than plunging directly downward. This option generates less stress and can prolong tool life but increases machining time.
Selecting the "Add tabs to toolpath" allows you to place tabs with a user-defined length and thickness along the perimeter of a part. Tabs locations are marked with a "T" below.
The tabs are marked by green semi-circles in the resulting toolpath below.
Tabs keep the part attached to the stock material to prevent shifting or early release and will need to be removed manually after machining.
