VS3D Machine Mode
The Cutting Tool settings define the spinning profile of the cutting bit.
"Type" : This setting specifies the basic geometry type of the tool - "Flat", "Cone", "Ball", "Ball Taper", "Parabola", or "Router".
"R" : This field is for the Radius of the tool.
"O" : This field is for the central Offset the tool.
"H" : This field is for the Height dimension of the tool.
"D" : This field is for the maximum cutting Depth of the tool (measured from the tip). This does not apply when the protocol Machne Type is "Laser".
Pressing the the keyboard "Enter" key in the "R", "O", "H" , or "D" fields will cause the specified cutting tool profile to be drawn in the Cutting Tool display window. The profile is not drawn if the "R" field is 0. For a valid tool, "R" and "D" must be greater than 0. "O" must be less than "R". The "O" setting (when greater than zero) can be used to specify "bullnose" and other types of special cutting bits. If the tool type is "Ball Taper", then the "O" parameter specifies the radius of the tip. When using a Contour machining path, the tool paths will be offset in the XY plane by the "O" parameter (or the "R" parameter when the tool type is Laser). The "H" setting does not apply to the "Flat" tool type.
Favorite cutting tools can be saved and loaded via the main "File / Cutting Tool" menu.
Note: When using a Cone ("V") tool bit to engrave on a flat surface, best results are obtained if the radius ("R") value is entered as the tool's actual radius at the cutting depth that it will be used at. For example, imagine a cone tool bit that has a radius of 0.25" at a depth of 0.5" and a radius of 0.5" at a depth of 1.0" . If this tool is only going to be used for cutting on flat surfaces at depths of 0.5" or less, enter the "R" radius value as 0.25 (even though the unused upper part of the tip has a larger radius of 0.5"). In other words, for a Cone tool, don't set the "H" parameter value larger than the "D" parameter value when cutting into flat (or nearly flat) material. The smaller effective radius will allow VS3D's tool path algorithm to work the tool into tighter places during Contour paths.
