Parameterization

Assignment of the system variables $TC_DPVx[...]
A differentiation is made between the following tool types in accordance with the specification
in system variable $TC_DP1[...]:
● $TC_DP1[...] == 400 ... 599 ⇒ turning/grinding tools
● $TC_DP1[...] <> 400 ... 599 ⇒ milling/special tools
The basic tool orientation programmed in $TC_DPVx[...] is assigned to the coordinate axes
depending on the tool type.
The tool type may be changed over by the setting in setting data SD42950
$SC_TOOL_LENGTH_TYPE (as described in Chapter "Assignment independent of tool type
(Page 172)" for tool length components).
If no other orientation is defined in setting data SD42954 $SC_TOOL_ORI_CONST_M and
SD42956 $SC_TOOL_ORI_CONST_T (Page 173), the standard case (G17 for milling/special
tools, G18 for turning/grinding tools) applies for assignment of the system variables
$TC_DPVx[...]:
Tool type
Turning/grinding tools
Milling/special tools

0 The function "Parameterizable basic tool orientation" is not active.
1 Activation of system variables:
● Function selection: $TC_DPV[...]
With the system variable $TC_DPV[...] = 1, 2, ... 6, one of six predefined basic tool orienta‐
tions can be assigned for each tool cutting edge D=<d> of a tool T=<t>.
2 Activation of system variables:
● Function selection: $TC_DPV[...]
● Orientation vector: $TC_DPV3[...], $TC_DPV4[...] and $TC_DPV5[...]
With the system variables $TC_DPV[...] = 0 and $TC_DPV3[...], $TC_DPV4[...] and
$TC_DPV5[...], any orientation vector can be assigned for each tool cutting edge D=<d> of a
tool T=<t>.
3 Activation of system variables:
● Function selection: $TC_DPV[...]
● Orientation vector: $TC_DPV3[...], $TC_DPV4[...] and $TC_DPV5[...]
● Normal vector for the orientation vector: $TC_DPVN3[...], $TC_DPVN4[...] and
$TC_DPVN5[...]
With the setting $TC_DPV[...] = 0, any orientation vector can be assigned for each tool cutting
edge D=<d> of a tool T=<t> with the system variables $TC_DPV3[...], $TC_DPV4[...] and
$TC_DPV5[...]. Additionally, a normal vector can be defined for the orientation vector with the
system variables $TC_DPVN3[...], $TC_DPVN4[...] and $TC_DPVN5[...].
