In order to achieve the best chip control during the thread turning operation, a modified
flank infeed should be used.
Modified flank infeed has many advantages:
• Fewer passes can be used compared to radial infeed.
• Chip is easier to control during process.
• Chip is thicker but created along one side of the insert making it easier to cut.
• Heat created during the cutting operation mostly transferred to the workpiece not
to insert.
Recommended for all operations and insert types.
For CNC programming use Carmex tool wizard.
