                      Full 4th Axis Machining
                            LABORATORY 8
Purpose:  This exercise will cover the basic procedures for full 4th axis machining using OneCNC.   File importing, coordinate systems, CNC options, tool selection, and tool path generation will be covered.

Objectives:  After completing this exercise you should be able to perform the following:

1. Import a model into OneCNC
2. Edit the file for delineating required geometry
3. Set the coordinate system for full 4th Axis Machining
4. Select the geometry to be turned
5. Specify tooling information required
6. Modify cut control as necessary
7. Generate a tool path for the part specified
8. Post process tool path for a HAAS lathe
9. Save the file as a PLAIN ASCII format
10. Download file to the HAAS VF1 lathe
11. Run the program (under supervision) and produce the required part.

Procedures:

Prior to using OneCNC, create a model or 2D drawing of part shown in the following section.  You may create the geometry using a 3D package of your choice (i.e. ProE, ProD) or create using AutoCad or equivalent.

Steps necessary for creating a tool path are provided with graphical illustrations .
Major steps include the following:

STEPS:
   1.  Create Model, import into OneCNC as IGES file
          2. Edit and remove non-essential lines
               3. Make sure that 4th axis (full options is selected)
                    4. Rotate the part (if necessary) so that rotation will be about the X axis (this is called the "A" axis).
                          5. Move object so that 0,0 is located at the center of the part on the "free end"
                               6. Again, verify that are in the full 4th axis mode.
                                    7. Select the start and finish location along the "X" axis.
                                         8. Select the start/end and incremental angle
                                              9. Click DONE and edit tool information
                                                   10. Select tool and make sure a .375 inch ball end mill is selected.
                                                         11. Save and post for  HAAS
                                                               12. Run a simulation for the part to be produced and record estimated machining time.
                                                                   13.  Have your lab instructor verify your program execution and sign off for completion.
                                                                    13.  Write lab report and submit

The following part will be produced on the HAAS VF-1 using an HRT210 rotary table.
