Tool, Offset Value, Feed And Spindle Speed (T, D, F, S, V) - Siemens SINUMERIK 840D Operating Manual

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.
CAUTION
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.
