This paper presents the use of vibration analysis of the drilling and engraving process in a PCB milling machine to indicate the presence and progression of damage incurred. An ETS PCBmate-300 W milling machine is used during the experiments and no coolant is used in order to accelerate damage to the machine.

Likely you should use even lower feed rate for drill sizes over 2mm (or thereabouts, I got up to 1.5mm without problem when things started to go south) or get a machine with fully metallic Z-axis assembly (like some CNC3040's for example, with 300W motor and full aluminum cast motor clamp & full metal other parts of the z-axis).

for designing, , etching as well as drilling. Therefore to Another method uses microcontroller the c programming. reduce time and more effort we are design this project. In this The system consists of three 3 stepper motor and one AC paper, the design of a PCB milling and drilling machine, where motor to control drill. Thus due this the ...
