grabcad

Feel free to build this CNC machine!This is my final year project which I did to earn a degree in Mechanical Engineering at the Faculty of Technical Sciences in Bitola, Macedonia. Modeled in SolidWorks 2016. FEA made in SolidWorks 2016.Rendered with KeyShot.Calculations made by hand.NOTE: Ballscrews are not added in the 3D model but the builder should account for them as well - and I have specified which ballscrews to use for each axis.Here's some more detailed specs: Profiles needed (steel S235JRH / EN10219) - for more details refer to the 3D model: 60x40x480x60x4100x60x5120x80x5X-axis: RM2510-2450 ballscrew + BKBF17 bearingsSBR25-2500 linear slide + SBR25UU sliders6.35 to 12 couplerNEMA23 600oz-in stepperY-axis: RM2010-1250 ballscrew + BKBF15 bearingsSBR20-1300 linear slide + SBR20UU sliders6.35 to 12 couplerNEMA23 600oz-in stepperZ-axis: RM2010-300 ballscrew + BKBF15 bearingsSBR20-350 linear slide + SBR20UU sliders6.35 to 12 couplerNEMA23 600oz-in stepperOther components:Omron limit switchesEmergency switch Gecko G540 driver Power supply Links to components: http://www.ebay.com/itm/ballscrew-RM2510-2450mm-SBR25-2500mm-linear-slide-rail-BKBF17-10-12mm-Coupler-/262553304207?hash=item3d21657c8f:g:ZWMAAOSwtnpXkHTKhttp://www.ebay.com/itm/ballscrew-RM2010-1250mm-SBR20-1300mm-linear-slide-rail-BKBF15-10-12mm-Coupler-/262547665500?hash=item3d210f725c:g:ZWMAAOSwtnpXkHTKhttp://www.ebay.com/itm/ballscrew-RM2010-300mm-SBR20-350mm-linear-slide-rail-BKBF15-10-12mm-Coupler-/262547480829?hash=item3d210ca0fd:g:ZWMAAOSwtnpXkHTKhttp://www.ebay.com/itm/Gecko-G540-Rev-8-3-Nema-23-600oz-1-4in-48v-12-5a-Power-Supply-2-2KW-Spindle-/131564173895?hash=item1ea1d5fa47:g:6DUAAOSw9N1Vs8IL
