What
I did
01
Modelled the parts in SolidWorks.
02
Printed the blue PLA brackets on a Soon FDM printer.
03
Machined 5A02 aluminium axles that turn on four M10 pivot bolts.
04
Fitted POM wheels.
05
Cut a 150 by 110 mm acrylic plate on a CNC mill from a Mastercam program.
06
Checked the cutting data of program O0100 in the report and modelled the rotating mass.
+ Honest result
What the report checks
The report checks the cutting data of program O0100 and models the rotating mass of the car, with an equivalent mass of 43.0 g.
