Anders,

My cnc experience was primarily with WEDM
( i discount the larger time spent in sink edm as it's pretty much
point and shoot not contouring )
but we were always constrained to a 'tangential contour' ,meaning each
path element could not be blended.
( it could have geometry truncated by linuxcnc , where a larger radius
might circumvent a smaller one to maintain velocity )

A line continuing into an arc was necessarily tangential ( so sayeth
the manufacturer AGie )
I believe the manufacturer wanted tangency for the xyuv style radii,
and that velocity was not a problem.

1) do 'tangential' contours like this get blended anyway?
2) would contours like this benefit from the effort?
( I'd guess CADCAM could increase velocity by removing detail,
  and CADCAM could isolate slow parts of the cuts )

thanks

ps: I dont have access to such papers, maybe you could let me see it, thanks
