Part Geometry

TURN Module requires Solid, Surfaces, Polygon Meshes, Regions/Curves that define the part geometry.  Since all parts that can be created in a 2-Axis turning machine are solids of revolutions, it is enough to describe the profile that needs to be revolved to create this shape.  The profile can be created in VisualCAD as a region or curve. TURN Module automatically creates the 2D silhouette of this part region when 3D Solid or Surface geometry is selected as TURN part geometry.

 

tog_minusBasic steps

1.Make sure you have either a 2D profile or a 3D surface model visible.

2.From the TURN Program tab, select Part and then pick Select Turn Part.

3.Define the Turn part using the Select Part Geometry for Turning dialog,

Watch how to do this (Similar or both RhinoCAM & VisualMILL)
tog_minusThe First Quadrant, XY Plane Restriction

Furthermore, TURN Module places a further restriction that these part geometries need to be constrained to lay only in the first quadrant of the ZX plane in turn coordinate system. This would essentially be XY plane (Top view) in world coordinate system in VisualCAD.
tog_minusIf Geometry Falls Outside the First Quadrant of the XY Plane

TURN Module will be unable to process a part region that fall outside the first quadrant. If the selected part region is outside the first quadrant, TURN Module will trim this to the first quadrant.

 

Example below shows curve region correctly positioned in the first ZX quadrant of the turn coordinate system touching both the X and Z axis. This would essentially be XY plane (Top view) in world coordinate system in VisualCAD.

Example of Curves Correctly Positioned within the First Quatrant of the XY Plane

Example of Curves Correctly Positioned within the First Quatrant of the XY Plane

Example below shows region not touching the X axis and/or Z axis

Part Profiles are Automatically Extended to the X and Z axis

Part Profiles are Automatically Extended to the X and Z axis

In such cases, TURN Module automatically extends the part regions to the X and Z axis when the regions do not touch the X axis and/or Z axis.

Note!Part regions need to be constrained to the first quadrant of the ZX coordinate system.

Note!Parts can be imported or can be created within VisualCAD using the Geometry creation and editing tools found under the CAD ribbon bar.

You can select 3D geometry (surfaces, solids or meshes) for defining the TURN part that contains milling features.  Such milling features are ignored while the turn part profile is being defined.
