Use Verify to identify and correct program errors before they reach the shop floor. Right-click in the graphics view and select Fit and Isometric from the menu. Mastercam Simulator should match the image shown below. View the Move List, which displays all pertinent information about the toolpaths being verified. The two Dynamic Mill toolpaths are able to machine the part in the time shown with the given parameters. The Dynamic Mill toolpaths easily and quickly remove all of the stock on the outside and prepares the part for any other necessary operations.
In the next lesson, you will create a Face toolpath to further machine this part. This toolpath can be based on chained geometry or on the current stock model. For this lesson, you will create a Face toolpath on the top of the part from the Dynamic Mill lesson. Exercise 1: Creating the Face toolpath 1. Open the part file, FaceMill, provided with this tutorial or use your part file created from the Dynamic Mill lesson.
If you are using your part from the previous lesson, select Toggle display on selected operations on the Toolpaths Manager. This will hide the two Dynamic Mill toolpaths and keep the graphics view clean. If necessary, expand the Tool Name column to see the entire tool name. Creates a smooth controlled motion that cuts from the outside to the inside, main- taining a constant load on the tool with minimal entries and exits.
Sets the amount of stock to leave on the floors during machining. Sets the distance between adjacent passes in the toolpath. Sets the height that the tool moves up to before the next tool pass. Sets the height that the tool rapids before changing to the plunge rate to enter the part. Before clicking OK, you will first preview the toolpath. Previewing toolpaths allows you to view the toolpath before generating it so that you can make adjustments as necessary.
Exercise 2: Verifying the toolpaths You now verify the two Dynamic Mill toolpaths created from the previous chapter and the Face toolpath together. The three Dynamic Mill toolpaths are able to machine the part in the time shown with the given parameters. Mastercam Simulator color-codes each toolpath so that you can distinguish where each toolpath cuts the part.
The colors on the part correspond to those on the time bar. Using the Dynamic Mill toolpaths and the Face toolpath, you have quickly cleared the part to prepare it for finishing operations. In the next lesson, you create two Dynamic Contour toolpaths. Compared to its standard counterpart, the Dynamic Contour toolpath provides much more efficient cutting by using the entire flute of the tool.
Exercise 1: Setting up the stock 1. Open the part file, DynamicContour, provided with this tutorial. Exercise 2: Creating the first Dynamic Contour toolpath 1. In Solid chaining mode, the Chaining dialog box gives you options to manage the chaining of solid entities. The Pick Reference Face dialog box displays. This dialog box allows you to cycle through possible reference faces on a solid until you reach the one you want.
Select the Endmill1 Flat filter, and deselect any other filter. This ensures that you are only selecting flat end mill tools. Offsets the tool to the right or left of the toolpath. Offsets the machining region to ensure the tool does not engage too much material during the first pass of the toolpath when entering stock from the outside. You are not leaving any stock on the vertical and horizontal surfaces. Both parameters help define the shape of the stock removed by the toolpath.
Mastercam calculates the stock to remove along the contour wall by using these parameters. This measures absolute values from the origin 0,0,0. Sets the height that the tool moves up before the next tool pass. Depth determines the final machining depth and the lowest depth that the tool descends into stock.
You will select an edge for this toolpath. Exercise 3: Creating the second Dynamic Contour toolpath 1. The chain will display as shown below.
Reverse the direction if needed, using Reverse on the Chaining dialog box. This ends the chain so that you can start a new one that is not linked to the previous chain. Incremental values are relative to other parameters or chained geometry. Exercise 4: Analyzing the toolpaths You now analyze the toolpath.
Analyze Toolpath allows you to view toolpath properties, such as coordinates, dir- ection, operation number, and other information by hovering over the toolpath. Analyze Toolpath informs you of the operation number, the feed move, spindle speed, G1 and the line length, and the coolant code.
It also displays the start and end of the toolpath and of the section you are hov- ering over. If there is more than one toolpath displayed at the time, then toolpaths other than the one you are hovering over are dimmed. Continue hovering over areas of both toolpaths. Once you are satisfied, press [Esc] or Cancel out of the func- tion. Right-click in the graphics view and select Fit and Isometric, if necessary, so that the display matches the image below:. By using two Dynamic Contour toolpaths, the total machining time is approximately one minute.
Open the part file, PeelMill, provided with this tutorial. For this part, no geometry needs to be created. The bounding box will be accepted as it is. Exercise 2: Creating the first Peel Mill toolpath 1. This toggles the translucency of the current model and will help with selection for this first toolpath. Select the two edges shown below. Use Reverse if necessary to ensure both chains go in the same direction.
This adjusts the final tool engagement with the material. Click Top of stock to return to the graphics window to select the top of the stock of the part. The toolpath is copied below the original. There are now two Peel Mill toolpaths in the Toolpaths Manager. Copy the toolpath once more. You will now have three Peel Mill toolpaths in the Toolpaths Manager.
Copying and pasting toolpaths is helpful when you have to do similar cuts on the same part. In the case of these toolpaths, you will have to re-chain the geometry. Exercise 4: Re-chaining the copied Peel Mill operations In this exercise, you will re-chain the geometry for the Peel Mill toolpaths that were copied.
Select the chains shown below. Ensure that the chains are both going in the same direction. You may need to rotate the part or select Translucency on the View tab to select them. By doing this, you only need to select the chains for the toolpath without having to go through creating the entire toolpath again. The second and third Peel Mill toolpaths regenerate using the newly selected chains.
All three Peel Mill toolpaths will display as shown below:. Exercise 5: Verifying the toolpaths In this exercise, you will verify all three Peel Mill operations together. When creating similar toolpaths, copying and pasting saves time.
In the next lesson you create two Dynamic OptiRough operations and a stock model operation. In this lesson, you will create two Dynamic OptiRough toolpaths using different cutting strategies, and a stock model operation in order to rough out the part. Exercise 1: Setting up the stock In this exercise, you will create the stock model that will be used for the first Dynamic OptiRough toolpath.
If it is not displayed, select Levels from the View tab to toggle the display. This will add a small amount of stock at the top of the part. This will create lines and arcs based on the stock boundary. You will then use this geometry to contain the first Dynamic OptiRough toolpath. The stock model displays as a dashed outline in red. The geometry that was created with the Bounding Box also displays.
Exercise 2: Creating the first Dynamic OptiRough toolpath In this exercise, you create the first Dynamic OptiRough toolpath that uses this stock boundary.
Use window select or any applicable keyboard shortcuts to select the part body as the drive surfaces. This includes the blue caps, as shown below. Since you are creating a roughing toolpath, enter the following stock to leave amounts on the wall and floor. Double-click to activate the field. This returns you to the graphics window to select one or more closed chains of curves to limit the tool motion. In the graphics window, select the geometry at the top of the stock boundary.
You may need to change to Wireframe mode in the Chaining dialog box. From outside sets the toolpath to machine from outside the containment boundary moving in. This strategy is best used for machining cores. Select the Endmill3 Bull filter, and deselect any other tool filter. This ensures that you are only selecting bull end mill tools. Mastercam first machines all stepdowns, moving from pocket to pocket. After all stepdowns on a Z-level are machined to completion, Mastercam machines the stepups by next closest, in the safest cut order.
Determines the Z spacing between adjacent cutting passes. Sets the minimum toolpath radius to create in the operation. Specifies a minimum pocket size that Mastercam will create a cut- ting pass for. This helps with problems where Mastercam thinks that a pocket is large enough to accom- modate the tool, but the entry move is so compressed the tool is effectively plunging into the part. Creates high-speed loops into and out of each retract move. Outputs the rapid move between passes as a feed rate move instead of a rapid move.
This helps when the tool needs to make many irregular moves per pass to jump between different areas of the part. Exercise 3: Creating the Stock Model operation You now create a Stock Model operation that uses the previous operation as its source. This stock model will be used in the second Dynamic OptiRough toolpath to remove any remaining stock.
This will only display the toolpath you have selected. It will also clean up the graphics view when making modi- fications to the part or creating another toolpath. Naming your stock model based on which operation it is using is helpful, especially when you have a part with multiple stock model operations.
Stock Setup copies the values defined in the Machine Group Properties dialog box to corresponding fields in the Stock Definition page. The values are not associative. The stock model is generated by running the selected operation against the parameters on the Stock Defin- ition page.
Exercise 4: Creating the second Dynamic OptiRough toolpath You now create the second Dynamic OptiRough toolpath that uses the stock model you created in the previous exer- cise. Select Toggle display on selected operations.
This hides all selected toolpaths to keep the graphics window clean. In the Levels Manager, turn off the display of the Caps level and turn on the Stock geometry level to make it easier to select the drive surfaces. This sets the outer edge of the tool to be bound to the containment boundary. This option adjusts the inside or outside tool containment boundary.
When you enable this page, Mastercam calculates the cutting passes based on the remaining stock. This option is used in conjunction with Ignore small cusps.
Mastercam will output cuts that engage large amounts of material. Mastercam moves to the closest cut from its last position on the previous cut. Adds retracts to avoid intersecting boundaries a gouge boundary, or a boundary of material yet to be milled. Select Toggle display on selected operations to display toolpaths again, and select the second Dynamic OptiRough toolpath to view the newly created toolpath.
Exercise 5: Verifying the stock model and toolpaths In this exercise, you use Mastercam Simulator to verify your toolpaths and stock model. Verifying your toolpaths allows you to use solid models to simulate part machining against the selected stock definition. If necessary, right-click in the graphics window and change the view to Isometric and Fit the part to the screen so that it matches the image shown below.

We developed Mastercam Mill Solutions to provide powerful, stock-aware toolpaths and machining strategies for milling operations. It offers wireframe, surfaces, solids, and mesh design so that virtually any part can be designed and machined without requiring third-party add-ons, although it works seamlessly with specialized tools like Port Expert and Blade Expert.
But what are the three most useful tools for the average milling shop? If it does find this inefficient cutting, it automatically changes tool angles to bring chip thickness into the most effectual range. Dynamic toolpaths ultimately reduce cycle time and minimize tool notching and excess side load, which lengthens tool life.
Every cut made with a Dynamic toolpath sounds the exact same. This is because the cutting conditions seen by the tool are always constant — from the beginning of an operation, to the end. Starting with Mastercam , Dynamic OptiRough is available in all levels of our Mill software and can be easily accessed from the 3D gallery in Mill Toolpaths. This tool combines Dynamic Motion technology with advanced 3D model awareness.
OptiRough replaces multiple less efficient roughing techniques with one advanced, collision-aware roughing strategy.

Dynamic toolpaths ultimately reduce cycle time and minimize tool notching and excess side load, which lengthens tool life. Every cut made with a Dynamic toolpath sounds the exact same. This is because the cutting conditions seen by the tool are always constant — from the beginning of an operation, to the end.
Starting with Mastercam , Dynamic OptiRough is available in all levels of our Mill software and can be easily accessed from the 3D gallery in Mill Toolpaths. This tool combines Dynamic Motion technology with advanced 3D model awareness. OptiRough replaces multiple less efficient roughing techniques with one advanced, collision-aware roughing strategy. The secret to its success is how it uses bidirectional cutting motion with deep cuts to cut away material much faster and more efficiently than traditional methods.
One OptiRough operation can take a part from raw stock, to finish-toolpath-ready. Because of its 3D model awareness, you can be sure that a uniform amount of material is being left for finish machining — across the entire topology of a part. Stock Model gives users the ability to keep track of stock with an in-process model of the part that Mastercam stores and uses for different stages of machining.
