What engineers do when they're bored at work

[deth]

My friend and I, both mech eng, got bored so we modeled this in Pro Engineer and CNC'd it. the logo os 40mmx 100mm and the block is 5kg of mild steel. batman was drawn freehand by yours truly, lucky really, cuz i suck at drawing. the final plan is to make a latex mold out of itm and get some epoxy resin to cast some belt buckles :roll:

Hahaha , that is a lot of free time man , and the draw is not bad ...

thanx pato and yes, it took an ass long time to machine..something like 8 hours or so

hey deth, the machined bat logo looks so good in the photos at the first impresion I thought it was machined in an electroerosion machine,but not

what kind of cnc you have at the work? If only I could have one of those in school :roll:

nice, wish i have the equiment like that. i'm an ME major too but dont got those machines at home

im in mech eng at ubc... that's pretty neat, i took a machine shop course a few weeks ago, just to get familiar with fabrication techniques, but we didn't get to use any cnc stuff.

did u just sketch the bat on the surface of a block and extrude it? how did u figure out the dimensions of the bat to constrain the sketch?

the bit that was used on the finishing pass was only 2mm and i think had quite a bit of overlap, so the finish is quite good. where i was working last week they had several cnc mills cuz their business is to make dies for stamping. with some luck i should be working at toyota next week..i'll let u know what they have there

yes and no. yes it was drawn and extruded, but then cut again. if you look closely the bat and the base have a very slight curve to them. i just drew the bat freehand on its own seperate datum plane, and was referenced to the 0 point of the datum plane. ProE just figured out the rest.
