We understood that after finish drawing our rotors, AutoCAD output .dxf files, and it will be entered to the CAM software which will convert the design to G-code .G-code is the language that the CNC router understand and contains the instruction for the CNC router.
As mentioned earlier, we want the finished product customized to the dimension of a pill and the users will only need to enter the dimensions of the pills to get the specialised rotor.
We found out that .dxf files are plainly textfiles which can be edited via notepad and this word document contains details of the coordinates of each line drawn in AutoCAD ,this means that we can alter details of the design (height, width...) without having to use professional CAD software which can take months to master and can be time-consuming to change one detail of the rotors. The programme simply just needs the values of the pills then the programme will automatically output a rotor design which will match the specification user entered.
Afterwards, we tried to change some numbers in the dxf files, and we opened it with autoCAD.There were differences made to the design which therefore proves that we know that it is possible to alter the design without opening AutoCAD.
Now we know it is possible to alter the design by changing the dxf file(drawing interchange file), we now can focus on how we can manipulate the numbers to achieve the correct dimension of the design.
After a few changes to the file, we understood now the start and end of each line drawn are defined with coordinates.
