3d Model to Real product 2d Draft People + Machine 3d Model CNC + Machine: 3d printing, Machining, Laser cut
3d Printing Add + 더함 Good: Easy, Any shape, Prototype Poor : Rough, Slow, Material, Property https://youtu.be/pyFZKc356eQ
Machining Remove – 뺌 Good: Material, Precision Poor : Machine able shape, Very slow, Chip loss, Expensive https://youtu.be/3YzAl29Ag78
Laser cut Divide – 나눔 Good: All thin 2d shape, Fast, No tool cost Poor : Expensive equipment, Heat effected https://youtu.be/pMSyGOoesfM
Real product to 3d model 3d Scanning: 2d + depth = 3d, Outside surface, Fast / Area CMM: Precise, Point https://youtu.be/TTCiOoedUco https://youtu.be/lZaWx8-oetQ CMM : http://www.dukin.co.kr
Digital to Mass Production Digital model CNC machining Die and Mold Die-casting, Forging, Stamping, Plastic injection
Summary Industry 4.0 : Digital = Real world 3d model to product : printing, machining, laser cutting [CNC control] 3d model – Mold – Mass production
Digital manufacturing CNC machining: -Remove 3d Printing: +Additive Metamorphic: ~Forging
