• Consider Milling where possible.
• Use the "Chip Break" option in the Mastercam Toolpath itself.
• For "longer" sections, consider using a Part-Off Tool or Groove Tool, to machine several grooves, say 0.500 between the grooves. Then rough with a Turning Tool, and the cuts are now interrupted, creating shorter chips.
• As Matt mentioned; program heavier FPR (Feed-per-Revolution) values, to actually force the chip to break.

Get a Citizen  with LFV (low frequency vibration).   It breaks chips on every rotation.
