TUTORIAL SERIES FOR TUTORIAL 2ADVANCED MULTIAXIS – PORT TOOLPATH Advanced Multiaxis TUTORIAL 2 This tutorial covers Mastercam's Advanced Multiaxis Toolpath functionality. To apply thesetoolpaths to a 5-Axis machine tool, a customized post processor for your machine is required.Mastercam has a post available called Generic Fanuc 5X Mill that can be configured for severaldifferent machine tool styles. However, this is a very generic post in terms of language andability to handle different configurations.We recommend that you contact your local reseller for a professionaly configured post tohandle your machine's configuration to take advantage of your machine/control's fullfunctionality.In-House Solutions has a team of engineers dedicated to post development. Our developmentservices are available worldwide.www.inhouseposts.comYou may be required to program according to a certain style or methodology that is specific toyour machine/control/post. This may not be covered in this tutorial. For instance:You may be required to position your stock with respect to the machine zero position asopposed to having a local part datum.You may be required to use the Misc Values boxes for input to the postYour post may need to prompt for tool gauge lengths to compensate for tool lengthThe nature of the additional information required depends largely on yourmachine/control/post. Contact the developer of your post processor for details. Page 2-2 Advanced Multiaxis TUTORIAL 2 Objectives: The Student will machine an engine inlet using an Advanced Multiaxis toolpath consisting of:Creating a 5-axis Advanced Multisurface Port toolpath.The Student will check the toolpath using Mastercam Verify verification module by:Defining a stock as a solid.Running the Backplot function by simulating the axis substitution and the rotary axis.Running the Verify function to machine the part on the screen.The geometry file, Port_Geometry.zip, can be downloaded from www.emastercam.com/files underAdvanced Multiaxis Mill X⁴The finish part, including the toolpaths, is also provided on the same location www.emastercam.com/files Page 2-3 Advanced Multiaxis TUTORIAL 2TOOLPATH CREATIONSTEP 1: SELECT THE MACHINE AND SET THE MACHINE GROUP PROPERTIES.Machine typeMillSelect Mill Default.MMDSelect the plus in front of Properties to expand the ToolpathsGroup Properties if necessary.Select the plus signSelect the Tool Settings to set the tool parameters and the partmaterial.Tool settingsPage 2-4 Advanced MultiaxisChange the parameters to match the following screenshot.Assign tool numberssequentially allows you tooverwrite the tool number fromthe library with the nextavailable tool number.

Page 2-5 Advanced Multiaxis TUTORIAL 2STEP 2 MACHINE THE INSIDE OF THE PART USING ADVANCED MULTIAXIS -PORT.Advanced Mutiaxis provides enhanced 5-axis multisurface machining strategies. You can work with thefull interface that gives you access to all the available parameters and options. You can also choose froma number of simplified interfaces that have been customized for specific applications and machiningstrategies.These toolpaths work on surfaces. Solid selection is available for most advanced multiaxis toolpathstrategies, with the following exceptions: toolpaths that require the selection of a defined edge (solidedge) and toolpaths that require the selection of only a single surface (solid face).Port toolpath is used to create a head porting toolpath. For each cut, Mastercam will project the leadcurve onto the drive surfaces, keeping the tool aligned so that the tool axis passes through the selectedpoint.Step Preview:ToolpathsAdvanced MutiaxisSelect the OK button to accept the NC file name.Page 2-6 Advanced Multiaxis TUTORIAL 2Scroll down and select Port in the Select 5axis App Type list.Click again on the Port button.If using a simplified interface, remember that you can always go back to the full interface by clickingSwitch to Advanced Interface on the Misc tab. This will bring your current strategy over to the fullinterface so it’s a nice way to help you through the initial setup and selection process. You will find thatthe full interface gives you much more control over your toolpaths.Right-mouse click in the tool list window and select Create new tool.Page 2-7 Advanced MultiaxisClick on the Lollipop Mill as the Tool Type.Change the parameters of the tool as shown in the screenshot below.Page 2-8TUTORIAL 2 [...]...
