dive into some fundamental G codes frequently used in Haas milling G00 Rapid Traverse This code tells the machine to move as quickly as possible to a designated point without cutting Its essential for positioning the tool and for getting to the starting point of a program Visual Example Imagine moving the milling cutter from one side of a workpiece to another for a different cutting operation G00 will bring the tool there quickly Practical Example G00 X10 Y20 would rapidly move the tool to the coordinates X 10 Y 20 G01 Linear Interpolation This code instructs the machine to move along a straight line from one point to another while cutting The feed rate is specified alongside Visual Example Imagine precisely cutting a straight slot into a part G01 would control the speed and precision of the cut along that slot Practical Example G01 X30 Y50 F50 would cut a linear path to X 30 Y 50 at a feed rate of 50 mmmin 2 G17 Plane Selection This code specifies the plane XY for the current machining operation Often implied it ensures consistency Practical Example In most milling operations G17 is the default and therefore is often omitted G80 Cancel Canned Cycle Often used with
