Investigation of auto-generated 3D model

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.

Investigation

Now we have to investigate the relating methods and topics that possibly help us find a solution. The goal is to find the most efficient way to bring low volume, accurate, fast turn around manufacturing in house. 4 axis CNC Milling/Routing: CNC stands for Computer numerical control. Numerical control is the automated control of machining tools and 3D printers by means of a computer. An NC machine alters a blank piece of material (plastic or thermoformed plastic ) to meet precise specifications by following programmed instructions and without a manual operator. Computer Numerical Control is different from typical PCs in the type of software used to control the machine, which is specially customized and programmed with G-Code — a specific CNC machine language that allows precise control of features like speed, location, coordination and feed rate. A 4-axis CNC machine operates on the X,Y and Z axes like a 3-axis machine, but it also includes rotation around the X-axis, whi...

2nd week

CAM mach3 has a cam software called lazycam so we will be using it to be able to make the Gcode for the Mach3. CNC machine software Mach3 and Mach4 software will be used to run the CNC Machine, also a CNC usb controller software comes with the usb that could also possibly work into the making a router. Design of router: The design of router will be based with autocad, due that was the advised software to use but later on, we will do a research about it Errors we countered and how did we solve the problems: We did the building and fixing of the new CNC machine CNC machine not having a manual, search online and to contact seller No CNC calibration manual, search online and to contact seller Broken Mill needles, the solution will be to buy more Milling needles

Types of CNC used

5 different types of CNC softwares have been used: Mach3, Mach4, USB CNC Controller and PlanetCNC Mach3 Mach3 CNC Controller software will convert your PC into a fully functional 6 axis CNC Controller. Mach3 is one of the most popular CNC Controllers for both DIY and Industrial machines. Mach3 works on most Windows PC’s to control the motion of motors (stepper & servo) by processing G-Code. Mach3 is a feature rich program which is also easy to use. It works with other programs and will import DXF files, generate G-Code, fully customizable. Works with CNC Routers, Milling Machines, Lathes, Plasma Cutters and Lasers. Mach4 Mach4 is completely new software with less than 1% of the programming code in common with Mach3. It was written from the ground up to be expandable, flexible, and extremely responsive for use with very large files. Mach3 was designed for simple hobby machines and still serves this purpose well.  When quality, speed, and the ability to use or le...
