Calculation

Machining Time: Drilling

Created on · machining-time-drilling

Calculates drilling time including peck depth, retraction, and rapid feed per hole.

Drilling cycle

Drill diameter

Cylindrical hole depth

Point angle

Cutting speed

Feed

Holes

Peck depth

Chip-break retraction

Clearance distance

Rapid traverse

Dwell time

Rapid travel between holes

How to use the result

The calculation describes the specified model. Check the tool, workholding, and machine limits before use.

point length = d / (2 · tan(point angle/2))t_cutting = feed distance / (f · n)
