MCE 181: HW#1: WELDMENTS&SHEET METAL ■ REV-B

DUE: 02/16/16(TUE CLASS) 02/18/16(THU CLASS)

INSTRUCTIONS: Use Sheet Metal and Weldments to create the assembly file shown in FIGURE

HW#1-1.

 Create the weldment as a part file shown in FIGURE HW#1-1 using the instructions per

exercise MCE181-CE#1 WELDMENTS. Use the 3D sketch shown in FIGURE HW#1-2 for

dimensions. The structural members are 4”x4”x0.25” square tubes and the joints must be

trimmed/extended as shown. See FIGURE HW#1-4 for additional views on the joints.

 Add weldment end caps and 4 gussets with fillets as shown.

 Create an assembly file, import the weldment, and create the sheet metal as shown in

FIGURE HW#1-1. Side panels must be removable and the top and back panels must be

welded. For removable panels, use the hole series and smart fastener tools for ½-13

flatheads. Follow exercise MCE181-CE#2 SHEET METAL for design and dimensional

instructions on removable sheet metal, welded sheet metal, hole series, and smart

fasteners.

 Remove tangent edges, keep origin planes on center, and fully define the 3D sketch. The

file should not have any unsolvable or conflicting entities(yellow or red under the design

tree).

START FILES:

(1) ESTOP.SLDPRT,

(2) HMI.SLDPRT,

(3) LEVELER.SLDPRT,

(4) LIGHT CURTAIN-RECEIVER.SLDPRT,

(5) LIGHT CURTAIN-TRANSMITTER.SLDPRT,

(6) SCARA ROBOT.SLDPRT

SUBMITTING YOUR HOMEWORK:

o Make every part virtual (right click part on assembly>Make

Virtual) and save your assembly internally (this will remove

the references to external files).

o Name your file HW1, name, and student ID#.

o E-mail your file to [email protected]. Place HW1, your

name, and student ID on the subject line.

o NOTE: Make sure to test that your assembly file is fully

internal by re-naming the folder of the parts or opening the

assembly file on a different computer. The grading staff will

assume parts with broken references as nonexistent and

grade accordingly.
