1. ME 418 M8, M9, & M10 2015 Robert Peace rob.peace@usask.ca

2. 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

3.  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) M8

4. Dimensioned Drawing

5. Set-Up Sheet

6.  Video here, start with a shot with door open pointing out turret, chuck, stock etc. “Cup” Part Production

7.  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

8. M8 – ST-10 Stock Set-Up Facing Allowance 2.0 mm

9.  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

10.  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

11.  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

12. Working Envelop of ST-10

13.  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

14.  NC Configuration  Start number = 0, Increment = 1.0  Insert Block Numbers  Delete block numbers for the following:  1 st line %  2 nd line O0001  Last line %  Change O0001 to year (15) and your group: O1506 for group 6. Code Expert Settings for M10

15.  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

16.  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

17.  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

18.  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
