1.1 Basics

The Y axis

With a Y axis you can drill and mill a workpiece on its front, back and

lateral surfaces.

During use of the Y-axis, two axes interpolate linearly or circularly in

the given working plane, while the third axis interpolates linearly. This

enables you to machine slots or pockets, for example, with plane

floors and perpendicular edges. By defining the spindle angle, you can

determine the position of the milling contour on the workpiece.

The CNC PILOT supports part program creation with the Y axis in:

 DIN PLUS

 TURN PLUS contour definition

 TURN PLUS working plan generation

The separation of contour description and machining also applies to

milling with the Y axis. Contour regeneration is not available for milling

operations.

Y axis contours are identified with section codes.

The graphical simulation shows the milling operation in the familiar

lathe, front, and surface windows, as well as in the "side view (YZ)."

The B axis

Tilted working plane

The B axis makes it possible to drill, bore and mill in oblique planes. To

make programming easy, the coordinate system is tilted in such a way

that you can define the drilling patterns and milling contours in the YZ

plane. The actual drilling or milling operation is then performed in the

tilted plane.

The separation of contour description and machining also applies to

machining operations in tilted planes. Contour regeneration is not

available.

Contours in tilted planes are identified with the section code

SURFACE_Y.

The CNC PILOT supports part program creation with the B axis in DIN

PLUS.

The graphical simulation shows the machining operation in a tilted

working plane in the familiar lathe and front windows, as well as in the

“side view (YZ).”
