Q5. (a) The following are the typical blocks of a CNC program for CNC milling operations: N005 G01 G45 X100.0 Y50.0 Z10.0 F300.0 5480.0 M03; (1) NO05 GO1 G45 X100.0 Y50.0 Z10.0 F300.0 S480.0 MO3 ; : Line number : Linear interpolation : Tool length offset Plus :X, Y and Z coordinates : Feed rate 300 mm/min : Spindle speed: 480 rpm • Spindle, CW : End of Block A G code in CNC programming controls the movements of a machine dictating how and where a machine should move to machine a part. An M code in CNC programming controls miscellaneous machine functions, including starting and stopping specific actions or programs. The following are the typical blocks of a CNC program for 3D printing operations: 11 G1 F900.00 X100.00 Y50.00 210.00 E20.00; (2) 11 G1 F900.00 X100.00 Y50.00 Z10.00 E : Indicates the line of code and is used for reference : Linear movement : Feed rate 900.00 mm/min : Coordinates : Extrusion parameter E in CNC programs of 3D printing is usually the length of the filament which enters the extruder.
