To calibrate the setting of the homing and limits of the cnc machine.

Another set of trails into engraving into the wood.

To download the other possible CAM software.

Tomorrow search about a file that allows the reading of DXF files so the program can be made.

To prepare our first test run on the CBC machine,we needed some material to carve on.There were some pallets unattended in the office.Therefore we asked if we could disassemble it to planks of wood which we can use.

Calibration, understanding of the mach3 settings and trials in wood engraving to make a circle, and a loop.

the important part of yesterday was to find out that the lazycam did not allow the 3D design and 3D GCode of designs input in the format of DXF.

The 2 engraving tools broke 1 due to high velocity and less steps per seconds. and the other 1 due to the poor movement of the machines coordinates. as the engraving tool was stuck inside the wood and was made to move the right without moving it up to stuck it.

After many trials and error,and a few broken engraving tips,we successfully drew a rectangular loop on the plank.This proves that the Design is implemented correctly however this undermines a safety hazard as the spindle was spinning so quickly which create too much friction, lead to a slight temperature spike.The tip was burning the area it was touching.In the future if this machine were to be used for long period of time ,I would advise for a addition cooling system on the CNC router to avoid a fire hazard.

Last but not least ,since it got very hot after 4-5 minutes of operation ,it is obvious to point out that no one should touch the tip or the spindle until the it has cooled down .



The above figure shows the pattern we implemented .

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...
