Besides, the precision is reduced when a driller touches the PCB board, there will be a friction force that cause human hand shakes that lead to wrong drilling. In this final project, it is designed an CNC with interface for automatic CNC for PCB drilling. The interface is designed using Visual Basic.

Next, you need to set the origin for the PCB miller or CNC. This is done so that the machine knows from where it should start the operation. This is also vital in order to select the desired area on the copper board on which you want the PCB to be made. Select the 'move to xmin, ymin' option. This would move the milling head to the Zero by ...

Creating a PCB with using milling machine gives you a flexibility to modify your PCB board into any shape based on your needs and requirements. Before you get a hold of making PCB, you must create a schematic diagram and PCB prototype in order to give a clear idea what components you will be using and how they are connected using different ...

Try to design with common hole size as much as possible. This is to avoid changing the drill bits used by the machine. By having many types of hole sizes, the machine will have to change the drill bits and this takes time. The time taken will determine the cost of the PCB. Common drill bits sizes are 0.7mm, 0.8mm, 0.9mm, 1.0mm, 1.2mm, 1.5mm, 2 ...

The CNC Mill can machine many different materials, examples are steel, aluminum, brass, copper and plastic. A Mill is not designed for cutting wood and should not be used for that. Examples of operations that can be made in a CNC Mill is to cut a profile shape, engrave text, mill a 3D surface, drill holes and mill bearing pockets.

The system can provide services such as drilling, milling ...

It doesn't produce a final product. It's only part of the PCB process. A CNC mill will cut the tracks, drill the holes and cut your PCB out to size. A PCB printer can't drill holes or cut the PCB so it's even less useful. It would be great to have a machine that spat out fully working PCBs, I look forward to the day.

Example of a CNC drilling machine. The table on which the PCB sits holds the boards down within very little movement. "Drill wander" does occur, however. Thus, the need for tolerances can be critical for these processes. When a large volume of circuit boards are ordered, manufacturing will stack the production panels on top of each other.

When you click on the PROJECT tab you will see a .TXT_CNC file for each drill size you used. As you add sizes they will change the file name to .TXT_CNC_1, .TXT_CNC_2 and so on.
