Type of D programming
The type of D programming is defined via machine data.
This can be done as follows:
● D number = cutting edge number
● Free selection of D numbers
● Absolute D number without reference to the T number

D numbers ranging from 1 to max. 12 are available for every tool T<number> or
T="Name" (with TOOLMAN). These D numbers are assigned directly to the tool cutting
edges. A compensation data record ($TC_DPx[t,d]) belongs to each D number (= cutting
edge number).
The D numbers can be freely assigned to the cutting edge numbers of a tool. The upper
limit for the D numbers that can be used is limited by a machine data.
Independence between D number and T number can be selected in systems without tool
management. The reference of T number, cutting edge and offset by the D number is
defined by the user. The range of D numbers is between 1 and 32000.
Comment
; Load tool T1 and activate tool offset data record D1 of T1.
; The tool length compensations are applied.
; Load tool T4 and activate tool offset data record D2 of T4.
; Activate other cutting edge D1 for tool T4.
