4.4 Roughing Cy
cles
Tool position
It is important that you observe the tool positions (starting point X, Z)
before executing any of the roughing cycles in expanded mode.
However, they also apply for all cutting and infeed directions as well
as for roughing and finishing (see examples of linear cycles in figures
at right).
„ The starting point must not be located in the shaded area.
„ The area to be machined starts at the starting point X, Z if the tool is
positioned before the contour area. MANUALplus will otherwise
only machine the contour area defined.
„ If the starting point X, Z for internal machining is located above the
turning center, only the contour area defined will be machined.
(A = contour starting point X1, Z1; E = contour end point X2, Z2)
