Hello Allan and folks,
It is not easy but a real question of touch and eye balling.
You are able for it only with a smooth and well adjusted machine.
Obviously it is not for accurate jobs but for approximation on form
pieces it goes.
Try and play with a manual machine to get a feeling.
Always I recommend the people to learn first to work conventionally
with machines to get a feeling what you can do with a machine
And then the CNC machines will not get abused as by greenhorns.

In several occasions I hit hard with company owners that a simple
PC user would be appropriate for CNC programing.
In my eyes that is a big mistake. Obviously the opposite case is as
bad as the first.
1995: One US-engineer and 1 dump machinist were not able to
make one single prototype in 1 month working 9 hours day.
I needed 3 days programming by hand (about 3000 lines)....and
1 day to machine 12 of them (11 in specs)
Have fun
Sven Peter
