Tool, Offset Value, Feedrate And Spindle Speed (T, D, F, S, V) - Siemens sinumerik 840D sl Operating Manual

7.8

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.
CAUTION
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.
