ADVANCED MULTIAXIS – PORT TOOLPATH







Advanced Multiaxis

TUTORIAL 2






This tutorial covers Mastercam's Advanced Multiaxis Toolpath functionality. To apply these
toolpaths 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 several
different machine tool styles. However, this is a very generic post in terms of language and
ability to handle different configurations.
We recommend that you contact your local reseller for a professionaly configured post to
handle your machine's configuration to take advantage of your machine/control's full
functionality.
In-House Solutions has a team of engineers dedicated to post development. Our development
services are available worldwide.

You may be required to program according to a certain style or methodology that is specific to
your 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 as
opposed to having a local part datum.
You may be required to use the Misc Values boxes for input to the post
Your post may need to prompt for tool gauge lengths to compensate for tool length
The nature of the additional information required depends largely on your
machine/control/post. Contact the developer of your post processor for details.

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 under
Advanced Multiaxis Mill X⁴
The finish part, including the toolpaths, is also provided on the same location www.emastercam.com/files

Warn of duplicate tool numbers
gives a warning if you enter two
tools with the same number.
Override defaults with modal

STEP 2 MACHINE THE INSIDE OF THE PART USING ADVANCED MULTIAXIS -
PORT.
Advanced Mutiaxis provides enhanced 5-axis multisurface machining strategies. You can work with the
full interface that gives you access to all the available parameters and options. You can also choose from
a number of simplified interfaces that have been customized for specific applications and machining
strategies.
These toolpaths work on surfaces. Solid selection is available for most advanced multiaxis toolpath
strategies, with the following exceptions: toolpaths that require the selection of a defined edge (solid
edge) 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 lead
curve onto the drive surfaces, keeping the tool aligned so that the tool axis passes through the selected
point.

Scroll 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 clicking
Switch to Advanced Interface on the Misc tab. This will bring your current strategy over to the full
interface so it’s a nice way to help you through the initial setup and selection process. You will find that

the full interface gives you much more control over your toolpaths.
Right-mouse click in the tool list window and select Create new tool.
