Parameters of Curves
Application Area:
The 6D Contouring operation allows for path creation using two varieties of Job Assignment lines:
5D Curve. The system generates the 5-axis tool path as the projection of the arbitrary curves on the part surface. In this case the tool tip will move in touch with the surface. Specify the surfaces or body to be projected on as the part of the operation.
Edge/Curve on Surface. Job assignment is formed with the edges of the part or any curves . If the edges if not highlighted when the mouse pointer goes under it then check the edges selection button on the filter panel ( the same applies to curves ). It must be down.
If the edge selection filter button is down but the edges is still not highlighted then sew the faces. If the set of the connected edges must be machined in one pass, then it must be selected from the screen together and added to the Job Assignment list by the one click on the Edge\Curve on surface button. In this case the edges are joined to the one item and machined as a whole. If the edges are added to the list separately then it is machined separately even if it is connected. Press and hold the Ctrl to select some objects from the screen at once. This option is most commonly used when it's necessary to mill surfaces with the side part of the mill. In this case, you can select the lower edges of the surface to be machined as the Job Assignment.
Item Properties:
Base Info:
Name. Specify a name for the item's appearance in the Job Assignment list.
Stock. This feature allows to shift both rough and finishing passes from the machined surface by the specified value. If the value is positive, the tool will follow a path outside the workpiece material at the specified distance. If the value is negative, the tool will cut the part material at the specified depth.
Selected Count. The number of selected items.
Project Curves Parameters:
Alternate Direction. This feature alters the toolpath direction along the curve.
Alternate Front Side. An edge/curve might relate to two different surfaces. Pressing this button allows switching between one of the two surfaces.
Properties:
An important advantage of the 6D Contouring operation of CAM system is its comprehensive set of features for adjusting the tool movement parameters along the curve . You can edit these parameters interactively in the graphical window or in the dialog window.
