CAMWorks How to Setup tool files to mill out a CO2 Dragster.
II.1.
Finis designing te CO2 Dragster as a !o"#$eted asse"%$&. Completing the full assembly is
ritial. !t is ritial in ase you ha"e to fi# or re$esign any feature on the balsa $ragster ar bo$y.Ha"ing to go bak an$ re$esign the blok is one hallenge% but ha"ing to ompletely re$o the tool path
is a ma&or issue an$ waste of time. A typial mistake a $esigner woul$ make% is not allowing enough
spae for the wheels. 'ither the two rear wheels are to big% $ue the fillets in the inner wheel wells being
too large beause the $esigner $i$ not use the setion ut "iew an$ notie$ his toleranes were toosmall. (his is the most ommon mistake% beause the $esigner $i$ not take in to aount the ra$ius of
the utter on the C)C *outer an$ or C)C Mill. (ypially a $esigner will either forget that the ra$ius of
the .2+, -./+0 mm1 utter is .2+, -/.3+mm1 an$ will use the $efault ra$ius of mm. (hus thewheels will not fit. So it is better to ompletely $esign an$ reate the $rawing for their CO2 Dragster
assembly.
