5. Mill Lesson 12 The Process
Geometry Creation
TASK 1: Setting environment
TASK 2: Create geometry – material blank 6.0 x x .75
TASK 3: Create the profile for the sweep on top of material
TASK 4: Trim geometry for the sweep
TASK 5: Create right hand section geometry for sweep
TASK 6: Create left hand section geometry for sweep
TASK 7: Create center section geometry for sweep
TASK 8: Create the swept surface
TASK 9: Create flat boundary surface at ends of sweep
TASK 10: Create fillet surfaces
TASK 11: Save the drawing
Toolpath Creation
TASK 12: Define the rough stock using stock setup
TASK 13: Rough the pocket using surface rough pocket
TASK 14: Finish walls using surface high speed (waterline)
TASK 15: Finish floor and fillets using surface high speed (scallop)
TASK 16: Rest passes using (waterline rest passes)
TASK 17: Verify the toolpath
TASK 18: Save the updated MCX file
TASK 19:Post and create the CNC code file

6. Demonstration of Mastercam?
Verify Lesson 12

7. Geometry Creation Tasks 1 - 11
Create the 3D box to represent the material
Create the profile for the sweep on top of material
Create right hand section geometry for sweep
Create left hand section geometry for sweep
Create center section geometry for sweep
Create the swept surface

8. Geometry Creation Dynamic Planes
For the center section geometry you will use Dynamic Planes
Dynamic Planes are an extremely useful function that allows easy visual manipulation of planes.
Origins can be created by snapping to entity features.
Coordinate system orientation can easily be changed by grabbing an axes and rotating it with the mouse. 8

9. Geometry Creation - Swept Surface
You create a Swept Surface by sweeping curves along a path. You define the
surface with two types of curves:
Across curves perform the sweep, defining the surface's cross-sections.
Along curves define the sweep's path or trajectory 9

10. Geometry Creation Tasks 1 - 11
Create flat boundary surface at ends of sweep
Create fillet surfaces 10

11. Geometry Creation Flat Boundary & Fillet Surfaces
Flat boundary surfaces are trimmed NURBS surfaces created within a boundary defined by a closed, flat chain
With fillet surfaces you can create one or more fillet surfaces, each of which is tangent to two surfaces. 11
