Rapid traverse motion
4.1 Straight line interpolation
Code G01
The straight line interpolation is used to move the tool with an exactly de-
fined speed along a straight line from the current position to the pro-
grammed destination point.
All axes can be traversed simultaneously, in which case the resulting line
of motion can lie anywhere at an angle within the working space. For this
the control unit requires a specified feed rate which at the latest must be
defined under the address "F" in the block containing the Code G01.
The following example describes the milling of a slot with absolute dimen-
sioning as per the drawing A shown below..
Programming example:
N10 T1 ; End mill
N20 M6
N30 G94 F300 S2000 M3 D1
N40 G90 G00 X40 Y48 Z2 M8 With rapid traverse to the starting po-
N50 G01 Z-12
N60 X20 Y18 Z-10
N70 Z2 F1000
N80 G00 Z200
N90 M30
The following program extract shows the milling of the same slot using in-
cremental dimensioning: (up to N40 see above.)
