7.7 Tool, offset value, feed and spindle speed (T, D, F, S, V)
Generally, the following parameters are entered for a 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 of the 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 occur 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
Collisions may occur if you specify the wrong cutting edge number for some tools (e.g. a
flat chamfering drill with guide spigot or step drill) and then traverse the tool. Always ensure
that you enter the correct cutting edge number.
Tool length compensation
Tool length compensation takes effect as soon as the tool is loaded into the spindle.
Different tool offsets can be assigned to each tool with multiple cutting edges.
The tool length compensation of the spindle tool remains active even after the program has
been executed (RESET).
Radius compensation
The tool radius compensation is automatically included in the machining cycles except for
path milling.
For path milling and straight line/circle, you have the option of programming the machining
with or without radius compensation. The tool radius compensation is modal for straight
lines/circles, i.e. you have to deselect the radius compensation if you want to traverse
without radius compensation.
