Machining attributes for form elements
All the basic contour elements contain the Chamf./round. form
element BR. You can define machining attributes for this form
element and all other form elements such as recesses and
undercuts.
Parameters:
BE: Special feed rate factor for Chamf./round. (default: 1)
Special feed rate = active feed rate * BE (range: 0 < BE <= 1)
BF: Feed per rot. – special feed rate for Chamf./round. during
the finishing cycle (default: no special feed rate)
BD: Corr. additiv for Chamf./round. (range: 901-916)
BP: Equidistant Allowance (at constant distance) for Chamf./
round.
BH: Absolut=0,Add=1 – type of oversize for Chamf./round.
0: Absolute oversize
1: Additive oversize
