                Session 103

                Build a 5-axis Mill Using STL Models

                This session describes how to define a Cincinnati T30 5-axis milling machine using CAD generated STL models to represent the component shapes. This session focuses on defining components and models to build a functional machine.

                The figure below shows the NC machine tool to be defined. The illustration identifies the machine coordinate system (XwYwZw axes), motion axes, and major components.

                A Fanuc 12M CNC milling control processes the NC tool paths.

                1. Start with a new Project file

                ? Launch VERICUT

                ? File > New Project > Inch

                ? Set your Working Directory by clicking on the toolbar icon

                2. Display Component and Model axis systems

                ? Right-click in the graphic area > Display Axes > Component, Model

                3. Load the Fanuc 12M Control file

                ?

                ?

                ?

                ? In the Project tree, select Project, right-click, Expand All Children In the Project tree, select Control , right-click, Open… Shortcut=Library File Name=fan12m.ctl, Open

                The following steps define the components from "Base" to "Tool". The components on the tool side of the machine are: Base > X > Y > A > Spindle > Tool

                This session shows you how to set component colors that will be inherited by models attached to the components later.

                4. Display the Component Tree

                ? Configuration > Component Tree

                5. Set the color for the "Base" component

                Select Base (0,0,0) in the Component Tree then, right-click and select

                Component Attributes

                ? Color=choose a different color (it is preferable to reserve the color red for errors)

                ? Apply (leave the Modeling window open to set colors on components that will be added) ? 6. Add "X" to "Base"

                With Base (0,0,0) selected in the Component Tree, right-click Append > X Linear

                ? In the Modeling window, Color=choose a color ?

                ? Apply

                7. Add "Y" to "X"

                With X (0,0,0) selected in the Component Tree, right-click Append > Y

                Linear

                ? In the Modeling window, Color=choose a color

                ? Apply ? 8. Add "A" to "Y"

                With Y (0,0,0) selected in the Component Tree, right-click Append > A

                Rotary

                ? In the Modeling window, Color=choose a color

                ? Apply ? 9. Add "Spindle" to "A"

                ? ?

                ?

                ?

                ?

                ?

                ? With A (0,0,0) selected in the Component Tree, right-click Append > Spindle In the Modeling window: Position tab Position=0 0 -12.5 Apply Component Attributes tab Color=choose a color Apply

                10. Add "Tool" to "Spindle"

                With Spindle (0,0,-12.5) selected in the Component Tree, right-click

                Append > Tool

                ? In the Modeling window, Color=White

                ? Apply ? The Tool component defines where cutting tools will be loaded. The Tool

                component must be defined prior to processing a tool path file, or attempting to move the machine via MDI . The Tool component origin is typically located at the intersection of the tool axis with the spindle face.

                The following steps define the components from "Base" to "Stock"

                The components on the stock side of the machine are:

                Base > Z > B >Attach > Fixture > Stock > Design

                11. Add "Z" to "Base"

                ? ?

                ? Select Base in the Component Tree, then right-click Append > Z Linear In the Modeling window, Color=choose a color Apply

                12. Add "B" to "Z"

                With Z (0,0,0) selected in the Component Tree, right-click Append > B

                Rotary

                ? In the Modeling window, Color= choose a color

                ? OK ? 13. Cut and Paste "Attach" to "B"

                ? ? Select Attach (0,0,0) in the Component Tree, then right-click Cut Select the B (0,0,0) in the Component Tree, then right-click Paste

                Notice that the Fixture , Stock and Design components all have moved with the Attach component.

                The Fixture component origin is the location where fixture models will be loaded. The presence of a fixture component in the machine definition does not affect how a tool path file is processed, however, is useful for detecting collisions between the fixture and other machine components.

                The Stock component origin is the location where the stock is located. Every machine definition must include this component type. The Stock component is typically connected to a Fixture component, but this does not have to be the case. The Stock component can be connected to any other component, but must be defined prior to processing a tool path file, or attempting to move the machine via MDI .

                14. Save a "5axmill.mch" Machine file

                ?

                ?

                ? In the Component Tree, select File > Save As Machine… Shortcut=Working Directory File Name=5axmill.mch, Save NOTE: Once a machine is saved, all the components that are attached to the Attach component will be saved in the Project file. The Machine file will not contain any Fixture , Stock or Design components, the branch will stop at the Attach component.

                15. Change the view to Machine and Cut Stock

                ? In the graphic area, right-click View Type > Machine/Cut Stock

                16. Add the "Base" model

                In the Component Tree, select Base (0,0,0)

                Right-click and select Component Attributes

                File Name=cint30ba.stl, Open

                Color=Inherit (colors can be selected for individual models to highlight

                details on the machine)

                ? Add ? ? ? ? ? ? ? ? ?

                Hint: Use Fit as needed throughout this session to see the entire machine, and

                use CTL+SHIFT+Left Mouse to rotate the models to view them.

                Note that the "cint30ba.stl" STL model file contains two shapes described in a single STL model file.

                17. Add the "X" model

                ? In the Component Tree, select Spindle (0,0,-12.5) In the Modeling window: Model tab Type=Model File Browse… Shortcut= Training File Name=cint30sp.stl, OK Add

                Model file shapes (STL or VERICUT) defined with the same origin as the machine, are typically located correctly as imported. When a component"s origin has been moved, such as often occurs with rotary components (or the Spindle component in this example), the model file shape must be moved in the reverse direction via the Model Definition: Position tab features to restore the proper relationship with the machine.

                ?

                ?

                ? Position tab Position=0 0 12.5 Apply

                Add Models to "Stock side" Components

                ? File Name=cint30z.stl, Open

                ? Add

                With the machine located at machine zero, the "Y" and "Z" components appear in a

                collision state. Since VERICUT machines are constructed with all components located at their respective zero locations, collisions during machine definition are common. A step follows (after adding the "B" model) to define an Initial Machine Location table to move the machine out of the collision state to its start-up position.

                22. Add the "B" model

                ? In the Component Tree, select B (0,0,0)

                ? In the Modeling window: Model tab

                ? Type=Model File

                ? Browse…

                ? Shortcut= Training

                ? File Name=cint30b.stl, Open

                ? Add

                ? Cancel

                23. Set an "Initial Machine Location" table to locate the machine

                at X0 Y60 Z62

                The Initial Machine Location table describe where the machine is initially positioned, how the machine moves when changing tools or spindles, and the location of the machine"s reference point.
