There are a few components that I feel are a must for
milling machine operations, but you may think differently.
Proxxon Precision Vise
The vise shown in Figure 12 can be used to hold your
stock. It makes setup and stock changes very easy. I will be
using this vise in my work flow examples.
Proxxon Bit Set
The bit set shown in
Figure 13 is a good starting
point for the end mills you
will need to machine various
materials. Again, I will be
using these here.
Proxxon MF70 Chuck
The collet set that comes
with the MF70 will work with
most end mills and popular
drill bits. If, however, you are
going to perform a lot of
drilling operations, you should
consider the chuck shown in
When referring to the PC interface, I mentioned the
use of a parallel cable. In the configuration of this
conversion, I will be utilizing a PC that has a parallel port.
These make the CNC virtually problem free when
configured properly. For this project, I built a PC using the
board shown in Figure 15. This particular board has a
built-in parallel port and an onboard CPU. All that we need
is to add memory.
Please note that Mach 3 is only compatible with a
32-bit version of Microsoft Windows with a parallel port.
That is what you will need to complete this project without
any variations. That said, there is a product called
SmoothStepper that will allow us to use the Mach 3 with
a USB interface and a 64-bit OS. I have even used the
SmoothStepper with my MAC.
As for building your PC, I do plan on a separate project
where I build a CNC PC.
