RE: [CAD_CAM_EDM_DRO] Re: Acceleration rates..

Dave,

Right. you can indeed do a curly q tool path for outside corners.
Also, with radius compensation you can sometimes do a sharp corner without
that.
The limiting factor is usually inside corners. Some controls may round this
to a parabolic curve
or even overshoot. A simple rule of thumb for deciding the accel you need is
just the
formula for centripedal acceleration though. To do an arc of radius R at a
speed V
you must have an accel of V^2/R. It's as simple as that. You can figure out
V
by the lowest speed you can go before chip load is too low and you get
burning or
other bad effects. You can then use the formula to calculate the accel.

I thought about the sharp corner thing and had the idea one could pass
the corner and do a circle and hit if from the perpendicular. it
would waste material, but offer a sharp corner.
