Input fields

The input fields in the "Roughing C" screen form have the following meanings:

Parameter Description

Length l1 Enter the end point of the contour in the axial axis here, taking the contour start position

("Reference z0") in the axial axis (Z axis) as the starting point.

Length l2 End point of filleting in the longitudinal axis (Z axis).

Length l3 Start point of filleting in the longitudinal axis (Z axis).

Diameter d1 Outside diameter of the "step" to be machined in the radial axis (absolute position of the X

axis in the diameter).

Diameter d2 Inside diameter of the "step" to be machined in the radial axis (absolute position of the X

axis in the diameter).

Radius r This entry value determines the size of the filleting, the center of the circle being calculated

internally. It is located on the imaginary line that is central and "normal" (90

) to the

imaginary connecting line between points "l2/d1" and "l3/d2". The choice of whether the

center point is on the side of the contour facing towards or away from the turning center is

determined by the "convex/concave" function key setting. If the radius entered is too small,

an error message will be displayed during machining (after NC start) since the contour

cannot be produced in this case.

Convex/concave This toggle key is used to specify on which side of the contour the circle center point should

be located. The circular machining direction, and hence the appearance of the finished

contour, is adjusted accordingly.

Max. infeed depth m1 Enter the maximum infeed depth for roughing. The internal infeed calculation ensures that

the infeed is as uniform as possible throughout the roughing operation. This entry value

represents the maximum value possible and is therefore not exceeded.

Finishing

allowance

m2 Finishing allowance in the X axis (m2x)

Finishing allowance in the Z axis (m2z)

The following possibilities exist for the position of the geometry:
