Drill Peck Calculator
The Drill Peck Calculator included in the Web Machinist program (bottom) is especially useful for deep hole drilling. Drill Peck Calculator can calculate several different drill peck options such as reducing the drill peck amount at a certain depth or reducing the drill peck by a determined amount from the very start of the drilling. Drill Peck Calculator can calculate drill pecks for both mills and lathes.
The Drill Peck Calculator gives you several options that are very useful for deep hole drilling. Drill Peck Calculator can calculate the same peck amount until a certain depth is reached then start reducing the pecks from that point (see example above). Minimum peck amounts can also be specified. There is also the option to have a dwell after each peck to allow the chips to to be flushed out and you also have the option of at what drill depth to start the dwells. The drill return amount after each peck can also be specified. Another option that Drill Peck Calculator can calculate is reducing each peck starting from the very beginning and and a dwell at each peck is also available. Drill Peck Calculator can also calculate the same peck amount at each pass with the option of adding a dwell at each peck.
As seen above, Drill Peck Calculator can also calculate deep hole drilling for lathes too. In the example above a reduced peck at each pass was calculated. All of the options described in the mill example above also apply to the lathe Drill Peck Calculator.
