1
Machining preparation
In this section you will practice the modeling and assembly techniques you
learned previously to create a manufacturing assembly. You will inspect the
part geometry and create the cutting tools needed for machining. You will
also create geometry groups in preparation for machining.
Step 1:
Create a new inch assembly named ***_bowl_mfg and immediately
add the existing component bowl_cavity-1.prt to your assembly.
Step 2:
Review the geometry for size, depth and shape.
Step 3:
Save the manufacturing assembly.
Step 4:
Option: At this time you can create a piece of geometry for the
Blank inside of Workpiece, or you will have to use the Auto Block
option in the Workpiece.
Step 5:
Start Manufacturing and use a Mill Contour CAM Session
configuration and a Mill Contour CAM Setup.
Step 6:
Create cutting tools that will be used to cut the part. The part will
be rough machined using a plunge milling operation.
The tools can be created with holders that would be similar to
holders on your machine tools.

Machining preparation

Create an endmill for this operation.
Diameter — 2.00
Length — 6.00
Lower Radius — .0469
Flute Length — 2.0
Flutes — 3
The next tool will continue the roughing process using a Cavity
Mill operation.
Create an endmill with the following parameters;
Diameter — 1.25
Lower Radius — .125
Length — 3.50
Create an endmill with the following parameters;
Diameter — .750
Lower Radius — .250
Length — 3.50
The following tools will be used for semi-finishing and finishing
using Fixed Contour operations.
Create a BALL_MILL with the following parameters;
Diameter — .750
Length 3.50
Create an endmill with the following parameters;
Diameter — .375
Lower Radius — .0605
Length 3.50
Step 7:
Change the Operation Navigator to the Geometry view. Edit the
MCS and locate per standards used in your shop.
Edit the Workpiece and add Part and Blank geometry. You can
use the Auto Blank or create a block in modeling to be used for
the blank geometry.

Plunge and Cavity Milling
2
In this lesson you will create Plunge and Cavity Milling operations to rough
out the cavity. You will create a Plunge Milling operation to rough the cavity.
Then you will create a Cavity Mill operation to remove any large scallops left
by the plunge milling operation. The process will continue with a smaller
tool to remove more material.
Step 1:
Continue using the part file ***_bowl_mfg.prt.
Step 2:
Create a Plunge Milling operation using the 2.00 diameter endmill
that you created in the previous activity.
Adjust the stepover to make a tool path that is acceptable to you.
If your practice is to use inserted tools the stepover will need to
take the size of the insert into consideration.

Plunge and Cavity Milling
Step 3:
Create a Cavity Mill operation to continue the roughing process.
You can use the 1.25 end-mill that was previously created. Set the
cut levels and other parameters to create an acceptable roughing
path.
Step 4:
Create a new semi finishing Z level operation. Use the .500
end-mill that was created in the first lesson.
2
You need to create a new Mill Area geometry to contain the tool
path to the inside of the cavity. The Method should be changed
to MILL_SEMI_FINISH.

Fixed Contour finishing
operations
3
In this lesson you will create Mill Area and Flowcut operations to begin
finishing the cavity. You will create a new Mill Area and a fixed contour
operation to finish the cavity. Then you will create a Flowcut operation to
cut the fillets and corners of the part.
Step 1:
Continue using the part file ***_bowl_mfg.prt.
Step 2:
Create a new Mill Area geometry. The bottom fillet of the bowl
and the inside of the bowl will be included. You will add this as a
child of the WORKPIECE.

Fixed Contour finishing operations
Step 3:
Create a Mill Area operation to begin the finishing operations. You
can use the .750 ball nose end-mill that was previously created.
Step 4:
Create a new finishing operation to remove material left in the
fillets of the cavity by the last tool. Use the .500 ball nose endmill
that was created in the first lesson. Create a Flowcut Reference
Tool operation. The reference tool will be the .750 tool used in
the last operation.
Step 5:
Additional operations may be needed to finish the planar faces of
the part. Create these operations using the tools and methods
of your choice.
