2.1.6
Feedrate for G63, tapping with compensation chuck
Application
G63
is a subfunction for tapping threads using a tap with compensating chuck. An encoder
(position encoder) is not required.
Speed S, feedrate F, thread lead
With
G63
, a speed
S
must be programmed for the spindle and a feedrate
F
for the infeed
axis (axis for thread length).
The feedrate
F
must be calculated by the programmer on the basis of the speed
S
and the
thread lead.
Feedrate
F
[mm/min] = speed
S
[rev/min] * thread lead [mm/rev]
2.2
Feedrate FA for positioning axes
Syntax
FA[<positioning axis>] = <feedrate value>
Functionality
The velocity of a positioning axis is programmed with axisspecific feedrate
FA
.
•
Effectiveness: Modal
•
Special points to be noted
–
No more than 5 axis-specific feedreates can be programmed in each part program
block.
–
The feedrate is always
G94
.
–
If no axial feedrate
FA
is programmed, the axial default:
MD32060 $MA_POS_AX_VELO (initial setting for positioning axis velocity) takes
effect.
Parameter: Positioning axis
•
Value range: Identifier of channel axes
MD20080 $MC_AXCONF_CHANAX_NAME_TAB
Parameter: Feed value
•
Value range
0.001...999,999.999 mm/min, degrees/min or 0.001, ...39 999,9999 inch/min
For more information about the value range of the axial feedrate see:
