Before launching SolidWorks:

Open Windows Explorer & Navigate to: 1. Copy: C:\Users\Public\Documents\my

MCamforSWx9

2. Paste it into: H:\My Documents (it has to be in MY Documents)

3. Copy part file: C:\Users\Public\Documents\shared mcamforswx9\ME418_2015_Cup-ForStudents.SLDPRT to your H: drive (location does not matter)

M8

4. Open SolidWorks 5. Accept the SolidWorks licensing agreement (if

it pops up) 6. Set help settings as desired (if it pops up) 7. Click on the arrow on the Options icon go to

Add-Ins and select Mastercam X9 for SolidWorks (NOTE: DO NOT select it to load at Start Up)

a. DO NOT Load Mastercam Direct 8. Agree to licensing agreement for X9 9. Do not choose to participate in the feedback

program 10. Open part file from H: drive (DO NOT OPEN

FROM Default location) 11. Wait for it to load (a few minutes potentially)

Set-Up Sheet

Video here, start with a shot with door open pointing out turret, chuck, stock etc.

“Cup” Part Production

Things to Ensure: Sketch on a Cardinal Plane Units are Metric Machine Type is USASK HAAS ST-10 Lathe

(Operations Manager) File Save location is H: drive (if it is left on C:,

you won’t be able to access it). If undo is unavailable, Esc the function and it

will be available.

M8 – Drawing for MasterCam

M8 – ST-10 Stock Set-Up

FacingAllowance2.0 mm

First is Always a Facing Pass with tool ID#1 Leave stock behind for finishing passes 0.5

mm. Always “From Tool” Reference points to ensure safe tool paths. Lead in/Lead out parameters for some tools

are required. Cut-off tool is always tool ID#9 and in

position 9. ONLY Tools listed in the Catalogue are

Available!

M8 – Tool paths

A printed, dimensioned (METRIC) drawing of your work-piece. SEE PAGE 6 for Details.

A printed listing of all tools used, in sequence.

Your part modelled in SolidWorks: Ensure Machine group is properly set. Set the Part-off Plane and Origin (see page 21

of the lab manual). Set the Chuck Jaws and Stock. All Roughing passes attempted.

Templates for set-up sheet, drawing and Job Card can be found on the ME 418 website.

For M9

Design Considerations (see lab manual 6-9). Maximum diameter = 50.8 mm Maximum length <= 2.5* stock diameter Keep the bar-stock as thick as possible close to

the chuck for as long as possible. Very small diameters can result in unstable

work pieces and chattering (poor surface finish).

Design should include circular arcs and straight lines.

Tool library is in the Lab Manual Late Penalties & Marking Scheme supplied

on pages 3-6 of the lab manual.

For M9

Working Envelop of ST-10

Code is generated within Mastercam using Code Expert.

Once the Code is generated, it must be debugged.

Step #1: Check the tools to ensure that

they are correct.

Code Generating & Debugging

NC Configuration Start number = 0, Increment = 1.0

Insert Block Numbers Delete block numbers for the following:

1st line % 2nd line O0001 Last line %

Change O0001 to year (15) and your group: O1506 for group 6.

Code Expert Settings for M10

Unmodified Code found on page 56 Debugging Tools:

Mastercam Backplot Shows tool path, rapid moves, tool and holder

Can be expanded (double blue triangles) to show coordinates D, Z, Y of leading edge of tool during run through, rapids and feeds different colors.

Can set to stop at any change in XYZ, (stop sign to right of progress bar).

Mastercam Simulation (Verify) Haas Simulators

The same as the actual controller on the lathe, can run code from USB, available via email appointment, will be used in M10.

CNC Code Debugging

G02: Clockwise G03: Counter Clockwise

In Code: G3 X Z I K Where: X and Z are the coordinates of the arc

end point(the start point is where the cutter is at the start of the arc)

I = X offset from the start point to the centre of arc

K = Z offset from the start point to the centre of arc I and K are used to specify the centre of the arc

Circular Arcs

N63 G0 G54 X0. Z70.5 N64 G81 Z40. R67.5 F.1

Drill cycle: Z = finish depth R = Retract value in Z, note: retracts rapidly

Drill Cycle

See Page 4-5 of lab manual. Two weeks after M9:

Completed SolidWorks File with tool paths - digital

Completed CNC Set-up sheet – hard copy Completed Engineer’s Drawing – hard copy

3 School Days before M10: Debugged CNC code – digital and hard copy.

Any corrections to drawing or set-up sheet. Drawing and set-up sheet – hard copy (only if

significant changes).

Due Before M10
