CNC lathe machine programing

Understand tool selection and operations on a CNC lathe, including two cutting tools for turning, center drilling, drilling sites, finishing, and reamer tools made from high-speed steel.

Turning removes material from the outer perimeter of a rotating workpiece to reach the desired dimensions, with roughing and finishing stages affecting surface finish, accuracy, and chamfering transitions.

Master drilling, reaming, boring, and tapping on cnc lathes by removing material from inside to create holes, accurate diameters, and smooth internal finishes, with drill bits in the tool holder.

Explore G00 rapid positioning on CNC lathes: simultaneous X and Z moves, diagonal tool paths, and how axis finishes interact. Learn about velocity override and cutter compensation commands G41/G42.

Learn how G01 performs linear interpolation in CNC lathe programming using absolute and incremental coordinates for the x and z axes, and control feed rate with overrides and memory behavior.

Learn how the G04 dwell command introduces a time delay in CNC lathe programs, with dwell values specified and two ways to write G04 in the block.

Explore switching between g20 and g21 units in cnc lathe programming, including inch and metric input and unit changes in the machine controller.

Explain how g28 moves the tool toward a reference point, using an intermediate point with x and z limits to avoid collisions and accommodate non-vector positioning.

Explore how G50 sets maximum speeds and coordinate system shifts on CNC lathe programs. Learn absolute and incremental coordinates, zeroing, and tool position tracking for finishing operations.

Explore cnc lathe machine programming with g70 finishing cycles, following roughing with zg71 and gs22. Learn how sequence numbers restore the tool to its original position after the finishing cycle.

Learn how the G70/G72 finishing cycle on a cnc lathe relates to G71, applies finishing cuts on the X axis, and structures the program with initial and finishing blocks.

Learn how g73 and g74 commands drive drilling cycles on cnc lathes, including drilling methods, finishing allowances, axis movements in x and z, and cycle repetition for material removal.

Explore G75 for drilling and grooving on the x axis and G76 for multiple threading. Learn how finishing allowances, depth control, and tool load are managed in these cycles.

Master the cnc lathe drilling cycle g81, starting at the initial point, drilling to z -21 and z -65, then returning to the start and canceling the g code.

Explain how G90 and G92 govern absolute and incremental coordinates in CNC lathe programming, including tool origin and movement, and when to use internal versus external cutting.

Learn CNC lathe programming with m00 to m09, including stopping with m01, optional stop m02, and end-of-program reset, plus spindle and coolant control.
