Blower Wheel Machining with TopSolid 7

Introduction

In this 7 step video series, you will learn how to machine a blower wheel within TopSolid 7.  This will include preparing your cad data, defining your stock model, selection of a machine, adding a fixture, and adding your MPS file to cut.  From there, you learn how to use Turning to machine as much as possible prior to moving on to 4 axis continuous roughing and semi finishing.  Lastly we will cover a few different types of 5 axis finishing.  Oh and don’t forget that you will also learn a lot of tips and tricks along the way too!

Prepare Data for Blower Wheel

Create an MPS document for the blower wheel in TopSolidIn this sample, we are assuming that the first operation has been completed by someone else.  So you will need to create a stock model that is representative of that. In Step 1, we will focus on building a custom assembly so that you can define your stock correctly.

In all reality, you have two choices here. You can create the custom stock directly within a MPS file (Machine Part Setup), or you can do it within an assembly file.

If you choose to use a MPS file, the creation of this custom stock will be tied to that MPS file.  This means that in the parametric world that is TopSolid, the birth of this custom stock block will be tied to the existence of the MPS file.  Now if this is a simple, one off part then this method works well. However if there is a chance that you might use this stock model another way, it is better to use an assembly first. Besides, if you start with an assembly, you will have more freedom as to how you design the stock model.  The video below will show you how to build the assembly first and then how to use it within a Machine Part Setup Document.

Setup the machine

Like in every real job, you have choices to make.  You need to select a machine to run a job on…choose fixturing and tooling and of course you need to setup the machine.  In TopSolid, it’s no different.  In TopSolid, we always start with machine selection.  It is a critical part of the manufacturing process that will affect how you hold the part and how many setups are required to machine the part. In this sample, we will choose a DMG CTX Beta 1250 TC to machine our blower wheel.

Select a machine for the Blower Wheel project in TopSolidIn Step 2, you will start by creating a new, empty machining document.  From there you will use the “select a machine” command to browse to and select the CTX Beta.  After TopSolid loads the machine definition, your next step will be to select and add the correct chuck and jaw combination.  In this case, you will browse to a sample chuck library and choose the 3 jaw Rohm chuck.  You will use standard windows drag-n-drop to include the chuck into the machining file.  Next you will use standard TopSolid constraint positioning methodologies to position the chuck.  Play close attention to the fact that the jaws on the chuck move in and out according to the stroke of that specific chuck as well!

Step1- Programming a Multus U3000 Machine Part Setup with TopSolid

Start with Machine Part Setup

Describe the stock condition while programming millturn machinesIn the first video of this 25-video series on programming a Multus U3000 with TopSolid, you will learn how to get started in TopSolid. You will start by opening the part to machine.  From there, you will add this part to a Machine Part Setup document (MPS for short).  It is in this document that you will tell TopSolid what the part to machine is and what the stock condition for the part is.  (For more information about a Machine Part Setup Document, please click here.)

Include your MPS into a Machining Document

Position the part while programming millturn machinesNext you will select a new Cam document by selecting a pre-created Machining template that already has the Okuma U3000 machine model and some basic tools loaded in it already.  From there you will learn how to include your MPS file into the Machining document.  It’s literally as simple as drag-n-drop to include.  Next up…positioning of the MPS file on your chuck. This part is very important. You want to be sure that you position your part correctly in the simulated environment. To position the part you will be shown a few of TopSolid’s powerful and simple-to-use assembly constraints.  (For more information about building assemblies within TopSolid you should check out this post here).

Once the part is loaded into the Machining document, you are now ready to make your first tool path.

Reviewing what you’ve learned

What you should pay close attention too in the video, is the simplicity of TopSolid.  Everything that you see in this video is being done in real time.  From the creation of the MPS file to the positioning of the part on the U3000 millturn machine.  Remember you’re working in a simulated environment in real time. You’re working this way because it makes more sense and is a far more efficient way to program complex millturn machines.  Why?  It makes sense because you want to know if you make a mistake, at the moment you make the mistake.  Not 2 days (or 3 weeks) later when you are running your program through a simulation.  By that point you have too much to lose.

Create a Machine Part Setup Document within TopSolid 7

Like all processes that exist in manufacturing, it is important to understand the process of how to send a part to be machined within TopSolid 7.  This process includes a special document type called “Machine Part Setup”.

It is this document that today’s video will cover.  In this video you will be shown various ways to send a part into a Machine Part Setup document.  But first, what is a Machine Part Setup document?

A Machine Part Setup document, or MPS for short, is a document that exists between the Cad document and the Cam document. Its sole purpose in life is to give you a simple way to describe the part, or parts to cut to TopSolid and also to describe the stock model to be used.

We created an intermediate document like this because we have found that our users always need a way to manipulate and edit the stock conditions of the parts they are cutting. And with this intermediate document, they can do this with ease.

The following video will introduce you to the basics of what an MPS document is and how you can use it.
