7 Machine Data
7.1 NCK machine data for ShopTurn
Setup feed rate
7-42
"Use the "Actual = Set" softkey to adjust incorrect values so that they meet the
minimum ShopTurn requirements. These are confirmed when you click "OK" to
acknowledge the query that follows.
If, for instance, the actual value is too low, the value of the machine data will be
set to the lowest setpoint. Where bit masks are concerned, only the missing bits
are set.
Caution
The tool length corrections are set in ShopTurn (setting data 42940
$SC_TOOL_LENGTH_CONST and 42950 $SC_TOOL_LENGTH_TYPE);
length 1 always refers to the X direction and length 2 always refers to the
Z direction irrespective of machining layer and cutting position.
Note
Please note that the machine data record also contains machine data for
configuring the memory.
For an exact description of all NCK machine data please refer to :

Use the SD 42600 JOG_FEED_PER_REV_SOURCE and
SD 43300 $SA_ASSIGN_FEED_PER_REV_SOURCE setting data of the rele-
vant axes to specify which setup feedrate will be evaluated in manual mode.
S SD 42600 JOG_FEED_PER_REV_SOURCE = --3 and
SD $SA_ASSIGN_FEED_PER_REV_SOURCE = --3:
When the main spindle is rotating, the JOG function uses the revolutional
feedrate. When the spindle is stationary, the feedrate for each minute is
used.
SD 42600 JOG_FEED_PER_REV_SOURCE = 0 and
S
SD $SA_ASSIGN_FEED_PER_REV_SOURCE = 0:
The feedrate used depends on the setting data
SD 41100 JOG_REV_IS_ACTIVE:
Bit 0 = 0 setup feedrate in mm/min
(with rotating and stationary spindle)
Bit 0 = 1 setup feedrate in mm/rev
The setup feed rates can be entered in the mask "Machine -- manual" → ">" →
"ShopTurn settings".
Use the option "Manual machine", enter the feed in the basic mask "Manual".
