Contour recessing, Recessing

The Cutting radius must be smaller than the smallest inside radius
of the recess contour, but >= 0.2 mm.
TURN PLUS determines the Cutting width from the recess
contour:
Recess contour includes paraxial floor elements with radii on
both sides: SB <= b + 2 * r (if radii differ: smallest radius).
Recess contour includes paraxial floor elements without radii or
with a radius on one side: SB <= b
Recess contour does not include paraxial base elements: The
Cutting width is determined from the recessing width divisor
(machining parameter 6 – SBD).
Abbreviations:
SB: Cutting width
b: Width of floor element
r: Radius

Drillg

Depending on the geometry of the bore hole, the AWG submode
determines the appropriate tool. For centric bore holes, TURN PLUS
uses stationary tools.

Cutting data and coolant

To determine the cutting parameters, TURN PLUS uses the
Materials (program head)
Cutting materials (tool parameters)
Machining operation (main operation in the machining
sequence)
The values determined are multiplied by the tool-dependent
compensation factors.
Further information:
Note for roughing and finishing operations:
Main feed rate for use of the primary cutting edge
Auxiliary feed rate for use of the secondary cutting edge
Note for milling operations:
Main feed rate for machining in the milling plane
Auxiliary feed rate for infeed movements
For threading, drilling and milling operations, the cutting speed is
converted into rotational speed.
Coolant: Depending on the workpiece material, cutting material
and machining operation, define in the technology database
whether coolant is used. The AWG submode activates the
appropriate coolant circuits for the respective tool.
If you have specified that coolant is to be used, the AWG submode
activates the coolant circulation for the respective machining block.
limitation: TURN PLUS limits the rotational speed to the
Speed
maximum speed specified in the TSF menu.
