9.8 Tool, offset value, feedrate and spindle speed (T, D, F, S, V)
The following parameters should be entered for every program block.
Tool (T)
Each time a workpiece is machined, you must program a tool. Tools are selected by name, and
the selection is integrated in all parameter screen forms of the machining cycles (with the
exception for straight line/circle).
The tool length offsets become active as soon as the tool is changed.
Tool selection is modal for the straight line/circle, i.e. if the same tool is used to perform several
machining steps in succession, you only have to program one tool for the first straight line/circle.
Cutting edge (D)
In the case of tools with several cutting edges, there is a separate set of individual tool offset
data for each edge. For these tools, you must select or specify the number of the cutting edge
that you would like to use for machining.
NOTICE
Risk of collision
If, for tools with several cutting edges, you specify the incorrect cutting edge number and move
the tool, then collisions can occur. Always ensure that you enter the correct cutting edge
number.
Radius compensation
The tool radius compensation is automatically taken into account during all machining cycles,
with the exception of path milling and straight.
For path milling and straight lines, you have the option of programming the machining with or
without radius compensation. The tool radius compensation is modal for straight lines, i.e. you
have to deselect the radius compensation again if you want to traverse without radius
compensation.
Feedrate (F)
The feedrate F (also referred to as the machining feedrate) specifies the speed at which the
axes move when machining the workpiece. The machining feedrate is entered in mm/min, mm/
rev or in mm/tooth.
