Introduction: Introduction to Workholding at the Pier 9 CNC Workshop

This class will introduce you to Workholding at the Pier 9 CNC Workshop for the Haas Mill, DMS 5-axis Router, and Matsuura 5-axis Mill. You will learn how to set up your CAM files in Fusion 360 HSM using custom templates that include precise models of the inside of each machine. Then, you will learn how to set up your vise, load your stock, and set your Work Coordinate System to prepare for machining.

Who should take this class? Pier 9 workshop users who have already been certified on either the DMS, Haas Mill, or Matsuura.

Why should you take this class? This course expands on CAM and machine skills that you have already built by giving you access to a new kind of workholding system, the Lang workholding system, that will increase precision of collision detection in CAM simulation, decrease setup/takedown time for each project because you will not probe your stock, and allow you to pause a project mid-machining or move a project from one machine to another with perfect registration.

How should I take this class? This course is set up differently from other courses because the lessons are not linear. Everyone should take Lesson 1, Introduction to Workholding, as well as Lesson 2, Introduction to Lang Workholding.

From there, branch off and choose the lesson that corresponds to the machine you want to use. Go to Lesson 3 for the DMS, Lesson 4 for the Haas Mill, or Lesson 5 for the Matsuura.

You will need an internet connection, a computer with Fusion 360 installed, and a USB drive. Download Fusion 360 here. If you are a student or educator, download Fusion 360 for free here!

Let's get started.

Introduction to Fusion 360 Template Files

You'll be using a Team Hub within Fusion 360, Team CNC at Pier 9, to access the dozens of workholding templates that we have created for each machine. These template files contain a wide variety of workholding configurations for each machine, featuring different vises, stock sizes, jaw orientations, and stock orientations.

Within the Team Hub, you will have a project labeled with your name that will be viewable and editable only by you and the Team Administrator, the CNC Lead at Pier 9. You cannot access anybody else's project files in the Team Hub unless they specifically share them with you.

When you access the templates, you will start by choosing a machine. Then you will choose the type of vise you are using, and then a vise and stock configuration (whether the jaws are facing in or out and whether the stock is high or low). Finally, you will drag your part into the file, create a joint between your part and the stock, and then check the CAM Setup settings. You will follow along with these steps inside each machine lesson.

In the next step, you'll learn how to access the Team Hub.

Accessing the Team Hub in Fusion 360

To begin the process of accessing every template file for the Pier 9 CNC shop, follow these steps:

1) Request access to your own folder within Team CNC at Pier 9 by emailing the CNC Shop Lead/Team Hub Administrator.

Use the email address that is associated with your Fusion 360 account.

2) You will receive an email invitation to access a folder titled with your name. Copy the link at the bottom of the email.

3) Paste the link into your browser, press Enter, and sign into your Fusion 360 account.

4) In the top right corner, click the bubble with your initials on it to switch from your personal hub to the team hub, CNC at Pier 9.

Within A360, you should see Team CNC at Pier 9 and your name in the top left corner. Inside your folder should be a sub-folder called Pier 9 Workholding.

Remember that there are many people working inside the team hub. However, all the contents of your personal folder are secret--other members of the hub cannot see your folder or access any files within it. You may modify the contents of this folder for your own personal use.

Open Fusion 360

5) Re-start Fusion 360.

If you haven't joined a Team Hub before, you should see a new splash page the next time you start up Fusion 360: "Welcome to Fusion 360 Team Hubs."

6) Open the dropdown by your name in the top right corner.

7) Switch hubs to CNC at Pier 9.

Now, you have access to every template file for the DMS, Haas Mill, and Matsuura 5-axis Mill at Pier 9.

How the Pier 9 Workholding Folder Works

The Pier 9 Workholding folder hierarchy follows a specific organization:

P9 Workholding/Machine/Vise/Jaw and Stock Orientation

You will follow these steps in detail in each machine lesson, but this is the general workflow:

--Choose a machine

DMS, Haas Mill, or Matsuura

--Choose how many vises you're using (for Haas Mill only)

--Choose a vise

There are four options: The small, medium, or large Lang vise, or the Lang 3-jaw chuck (for circular stock)

--Choose a jaw and stock orientation

For the vises (rectangular stock):

There are two jaw orientations: Jaws In or Jaws Out (dependent on stock size)

There are two stock locations: Part High or Part Low (dependent on surface finish and machining operations)

The naming convention is: Vise size_Jaw Orientation_Stock Location; for example: "Small_In_High"

For the 3-jaw chuck (cylindrical stock):

There are four jaw locations: 1, 2, 3, or 4 (Numbers get larger as stock diameter gets larger)

There are two jaw orientations: Jaws In or Jaws Out

There are two stock locations: Part High or Part Low

The naming convention is: Location #_Jaw Orientation_Stock Location; for example: "2_Out_Low"

In special cases, you will need to build your own template file. You will do that here:

P9 Workholding/Make Your Own

In general, you will follow these steps:

--Choose a machine base

--Drag the correct component into the machine base, such as a vise or tombstone + vise

--Create a joint between the component and the machine base. Repeat if necessary.

--Save your custom template file inside the P9 Workholding folder.

Watch this video for more information about the CNC at Pier 9 template organization. Then, spend some time in the Pier 9 Workholding folder to become familiar with the template files.

In the next lesson, you will be introduced to the specifics of the Lang workholding system.
