Back by popular demand is the ability to create one-off parts, nested panels and parts, and G-Code from all of them.
Smaller shops and others that know exactly the dimensions of the single parts they want to produce need this feature. It is a quick and easy way to produce single parts without using the full capabilities of Microvellum and its libraries.
Two interfaces within Microvellum support placement of custom drilling and routing machine operations. One accesses the 2D Part Editing Tools from the command "Modify > Draw Part in 2D," which requires you to select a 3D part to modify. The other is the "2D Machining Tools" interface that supports the direct creation of parts and the addition of machining to those parts, as discussed in this article.
The interface for "2D Machining Tools" is used for a different purpose than the 2D Part Editing Tools. Use the 2D Part Editing Tools to add machining to, or modify machining on specific existing parts. Use the 2D Machining Tools to create new nested sheets and add parts to them, or new single parts and add machining to them.
The top-level component on the 2D Machining Tools interface is a dropdown list for the selection of the processing station to use for your nests and parts. These are the same processing stations that are displayed within the Processing Center. Edit the Processing Station from this interface by selecting your station and clicking on the ellipsis button immediately to the right of the dropdown list, or leave it set to the default value that is displayed.
The second component on the 2D Machining Tools interface is a dropdown list for the selection of the Current Work Order. If a work order has been opened in the Processing Center already in this Toolbox session, the Current Work Order box will contain that work order name, as shown above. If the opposite is true and a work order has not been opened in this session, the Current Work Order box will be empty, as shown below.
Below that, the interface tabs are as follows:
This tab contains tools that you use to create nest sheets of a given size and material and add it to a work order.
There are also part placement tools for manipulating the parts on the nest sheet. Here are the Microvellum nest editing tools. The commands available here are "Move Part," "Copy Part," "Erase Part," "Rotate Part in Nest," "Change Parts Border Setmill Location" (reading left to right, top to bottom).
You may also use the AutoCAD commands for Move, Copy, Rotate, or Erase.
And finally, there are tools for miscellaneous operations in the "Machining" area. These include "Create New Machining Instructions and G-Code from Drawing," "Update G-Code Files from Drawing," "Show Machining Properties," "Make Center Line Nest," "Add Tab to Nest," "Assign Priorities to Routes," and "Assign Priorities to Borders."
This tab contains tools that you use to create single parts to add to a nest or to add as single stand-alone parts for a point-to-point machine.
There are tutorials outlining the specific steps necessary to add parts elsewhere in the Knowledge Base, but here are the general steps.
Fill out the Name, Length, Width, Border Tool in the Part Information section.
Click the Select Existing button to select AutoCAD closed polyline geometry that has already been drawn.
Click the Draw button to select a location in the drawing to locate the part. This can be either inside nested sheet borders or outside. If outside, a label is drawn containing the part name, dimensions, and material.
Use this tab to add vertical drill machining to either nest parts or single parts destined for the point-to-point machine. The tools available under this tab reflect those configured in the toolfile.
Use this tab to add horizontal drill machining to either nest parts or single parts destined for the point-to-point machine. The tools available under this tab reflect those configured in the toolfile.
Use this tab to add route machining to either nest parts or single parts destined for the point-to-point machine. The tools available under this tab reflect those configured in the toolfile.
Use this tab to customize existing route machining. These include: "Reverse Polyline Direction," "Change Setmill (used to modify the tool entry point in part's non-border machining operations)," "Step-Through Polyline," "Hatch Polyline (use for creating a pocket from a polyline)," "Show Center Line Path," "Settings," "Add Lead-In to Polyline," "Add Lead-Out to Polyline." If you need to modify the Z Value or Feed Speed of a polyline machining definition, use the "Select Polyline" button in the section Modify Polyline Properties and change the values in the appropriate text boxes.
Use this tab to add saw machining to either nest parts or single parts destined for the point-to-point machine. The tools available under this tab reflect those configured in the toolfile.
