Sorry I did not get to read the news group for a couple of days and did not
respond sooner.
As has already been posted by Mr. Henzi, causing a router to stop and then
restart along a different axis while cutting causes chatter. Mr. Henzi
explains exactly what I was going to say -- only he puts it far more clearly
that I would have.
As for your experience, could it be that you have never pushed the envelope to
the point where it has has become a problem? Could it be that the application
has been such that a little defect in the corner has not been a factor?
Also, keep in mind that we are talking about inside corners here. For outside
corners the cutter is driven past the end, backs up at a 45 degree angle and
then starts the pass off the edge of he board. This movement involves 2 stops,
but the stops happen in scrap material where the quality of the cut are not an
issue. The actual outside corner is cut with the cutter moving in a straight
line at close to a constant velocity.
