Why G01 G-code Linear Interpolation Used for in CNC Machining???

G-Code G01 Linear Interpolation.

G-CODE FORMAT:  N_G01 X_ Y_ Z_F

 Description:


G01 Gcode is a cutting movement following a straight line at a set feedrate (F).  G01 Specs the Start and the end points and the machine control calculates automatically the intermediate points to pass through to get a straight line.


Note:


1.        The G01 code is modal and is therefore incompatible with G00, G02 and G03 codes in the same block.

2.        The G01 code can be written into a program in two ways: G01 or G00.

3.       G41 or G42 Cutter compensation can be applied during G01.

4.       The axis co-ordinate moves following a G01 command can be programmed as either:

Absolute values (relative to a set datum point) are following setting of the G90 code or incremental values (relative to the last stated co-ordinate in the program) following setting of the G91 code.


Example:


N170 G90 G01 X50 Y100 F100
