SINUMERIK 840Di sl/840D sl/840D Operating Manual HMI-Advanced (BAD) - 01/2008 Edition
A tool is selected in the program with the T function. Numbers T0 to
T32000 can be assigned to tools. Each tool can have up to 9 cutting
edges: D1-D9. D1 to D9 activates the tool offset of a cutting edge for
the active tool.
The tool length compensation is applied with the first traversing motion
(linear or polynomial interpolation) of the axis.
A tool radius compensation is activated by programming of G41/42 in
the active plane (G17, 18, 19) and in a program block with G0 or G1.
Allowances for changes in the active tool shape can be made in the
tool length (tool parameters 12-14) and tool radius (tool parameters
15-20).
The so-called "flat D numbers" can be activated by means of NC
machine data. This means that tool management is no longer
available.
The D number range increases to 1 - 32000. A D number can be
assigned only once for each tool, i.e., each D number represents
precisely one tool offset data record.
T No. Tool number
D No. Cutting edge number
Every data field (offset memory) that can be called with a D number
contains not only the geometric information for the tool but also further
entries, i.e., the tool type (drill, milling cutter, turning tools with cutting
edge position, etc.).
