11、p controlCut Control / Parallel cutsThe parallel cuts option will create tool paths that are parallel to each other. The direction of the cuts is defined by the two angles. The angles in XY and in Z determine the direction of the parallel cuts of the tool path Imagine slicing an apple: You can slice

12、 it with a knife parallel from top to down or from left side to right side. The pictures in the dialog symbolize how to set the desired cutting direction using the angles. Cut Control / Cuts along curveWith this pattern the generated tool path is orthogonal to a leading curve. That means that when y

13、our selected curve is not a straight line the cuts are not parallel to each other. Cut Control / Morph between 2 curvesThis option will create a morphed tool path between two leading curves. Morphed means that the generated tool path is approximated between the tilt curves and evenly spread over the

14、 surface. This option is very suitable to machine steep areas for mould making. Cut Control / Parallel to curveParallel to curve option will align the cut direction along a leading curve. The neighbouring cuts are parallel to each other. Cut Control / Morph between 2 surfacesThis option will create

15、a morphed tool path on your drive surface. The drive surface is enclosed by two check surfaces. Morphed means that the generated tool path is approximated between the check surfaces and evenly spread over the drive surface. Cut Control / Parallel to surfaceParallel to surface means that the cuts of

16、on your drive surface will be generated parallel to a check surface.CNC Software developed toolpaths / Tool axis ControlCurve 5 ax optionsDrill 5 ax optionsSwarf 5 ax optionsThe walls define both the Cut Control motion and tool axis controlCurve 5 ax optionsFlow 5 ax optionsMsurf 5 ax optionsCNC Sof

The tilt axis can be the X, Y and Z axis. or any line created in the geometry. Tilted around axis: The tool axis has the same dir

Tilted through point: The tool axis is always pointing from a created point in your geometry to the surface point. Tilted through curve: the tool axis

23、 is aligned to a tilt curve. There are different option possible in which way this curve shall be aligned to the curve. Tilted through lines: The tool axis will be approximated along its tool path to lines you created in your geometry.Tilted from point away: The tool axis is always pointing away fro
