Step 3 – Programming a Multus U3000 – B Axis turning with TopSolid

Using the U3000 B-Axis to turn with

In the third video of this 25-video series on programming a Multus U3000 with TopSolid, you will learn how to use the B-Axis of the Multus U3000 to continue roughing the part.  As always, you will begin by selecting the geometry to machine.  From there you will select a neutral style turning tool that is mounted on the B-Axis of the machine.  Once you have the geometry and the tool selected you will learn how to set the B-Axis angle of the turret.  Finally, you will learn how to re-use the cutting conditions from the first operation by simple drag-n-drop.

Smarter Software with fantastic visualizations

TopSolid checks the insert angles for use with the U3000One of the first things that should be pointed out is that machine simulation and tool simulation are much more than just pretty pictures on the screen.  During this step, play close attention to the preview of the tool path based on the orientation of the neutral tool selected. You will see that TopSolid always is checking both the forward and the back angle of the insert based on the orientation of the tool and the angular solution of the B-Axis.  This is done automatically and in real time so that you are always sure to have the most accurate tool path possible.

Setting the B-Axis angle

Set the U3000 B-Axis angle in TopSolidWhen working with a machine like the Multus U3000 from Okuma, it is critical to understand what the machine can and more importantly cannot do.  It is crucial that you know that the machine is going to do exactly what you tell it to do.  In this example, you will learn how to set the B-Axis of the machine to be at 45 degrees.  What’s cool is that as you tell TopSolid to set the axis to that condition, TopSolid listens to you in real time and updates the graphic on the screen to reflect the change.  This way you are sure that you have entered the information correctly!

The simplicity of re-usability

Drag-N-Drop in TopSolid makes programming the U3000 even easier!One of the key development points behind TopSolid was re-usability. And TopSolid takes this to an entire new level.  In this video, you will learn how to reuse the cutting conditions from the first operation by simply dragging and dropping the first operation onto the cutting conditions button of the new operation.  The simplicity of this action is fantastic as the complexity of what’s actually happening is enormous!  When you drag-n-drop an operation onto one of the specific operation buttons, the software automatically copies all common parameters over to the new operation. In the case of cutting conditions this can be 10-15 parameters that get copied.  However, try doing this on other operations. For example, take an existing operation and drag-n-drop it onto the settings button of the new operation.  And presto!  All the common variables are now copied over!

Setting the correct driven point for a U3000

Set Driven point accurately for U3000 with TopSolidWhen working on a mill/turn machine like the U3000, it is important that you understand how to define the correct driven point for your turning tool when you are working on the B-Axis turret.  In the case where the B-Axis is either vertical or horizontal, you can use the standard driven points of the tool. However, if the turret is at an angle outside of vertical or horizontal, you will need to do some additional work to set the point correctly.

In this step, you will learn how to do exactly that. It will start by duplicating the TopSolid driven point.  From there you will activate the duplicate and the choose to rotate the point.  This is the key element here…the rotation of the driven point.  Because of TopSolid’s ability to offer this, you can affectively drive almost any tool from any angular solution with relative ease.

Reviewing what you’ve learned

In this video, you want to pay close attention to a couple of key elements. First, the dynamic simulation of the B-Axis.  Any change you make to the orientation of the B-Axis or even the orientation of the cutting tool is dynamically displayed to you in real time. This eliminates guess work on your side and also costly mistakes.

You should also pay attention to the simplicity of how you can reuse cutting conditions from a previous operation.  It’s just simple drag-n-drop!

Finally, spend some time practicing how you set the driven point of the tool. When you use custom B-Axis angles, this is a critical step to understand.

Step 2 – Programming Multus U3000 – Turn front face with TopSolid

Create your First U3000 Tool Path

In the second video of this 25-video series on programming a Multus U3000 with TopSolid, you will learn how to use the lower turret of the Multus U3000 to turn down the front face of the part. To do this, you will start by selecting the face to machine with the left mouse button.  Then you will right mouse click and choose Roughing from the Turning section of the contextual menu.   Once you get into the operation for rough turning, you will need to select your tool and set your cutting conditions.

Selecting a tool from the U3000 lower turret

Tool selection in TopSolid'Cam for the U3000To select the tool that you want to use, you need to click on the Tool icon from the operation icon bar.  Next, it is important that you select the turret where you want to select the tool from. In this samples case, it will be the lower turret.  Once you are viewing the lower turret, you can choose the appropriate tool by selecting the check box to the left of the tool number you wish to use.  In this sample, all the tooling is pre-loaded on the Multus U3000 Machining template.  This way, the common tools that are usually found on your machine are easy to use because they are already there!

Setup the rest of the operation for the U3000

Set Feeds And Speeds in TopSolid for the U3000Now that you have your tool selected, it is time to setup the rest of the operation.  In this first operation, you will use the Quick Settings Balloon to modify the depth of cut and the stock to leave.  As TopSolid is a fully certified Windows application, this can be done by just double left clicking on the field to modify.  If you pay close attention to the preview of the tool path, you will see that everything you change dynamically updates on the screen.

From there you will click on the Feeds & Speeds button in the operation navigation bar.  Once the dialog box is open, you will modify the settings to use constant surface feet. Once this is activated you will set the appropriate surface feet, chip load and finally the max RPM for the spindle.

Reviewing what you’ve learned

In this video, you want to pay close attention to the simplicity of how you create the tool path.  There are three main points to remember when creating any tool path in TopSolid.  You must:

  • Select an operation type
  • Select a cutting tool
  • Set Feeds & Speeds
  • Select geometry to machine
  • Tweak operation settings

That’s all that is required!  What’s even more impressive is that every single tool path command has the same requirements and the same way of being applied.  So really, once you practice a bit, you should be able to apply any tool path operation that your machine can handle!

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.
