Discover the process of calculating cutting time on a lathe with precision. Swiftly estimate the time required for your upcoming machining project using our user-friendly lathe-cutting time calculator.
Our Cutting Time Calculator helps determine the time needed for threading and cutting lathe operations based on length, tap diameter, and job revolutions per minute.
Lathe Operation Cutting Time formula
![\[Time for Tapping = \frac{L + \frac{D}{2}}{P \times r.p.m}\]](https://x-calculator.com/wp-content/ql-cache/quicklatex.com-444052058b2f41cd0e5e56ffef8ba312_l3.png "Rendered by QuickLaTeX.com")
![\[Time for Cutting = \frac{\frac{3}{2} \times (L + \frac{D}{2})}{P \times r.p.m}\]](https://x-calculator.com/wp-content/ql-cache/quicklatex.com-c075f4840f0124384b7e004d2058cb5c_l3.png "Rendered by QuickLaTeX.com")
where:
- P is the pitch of the thread in millimeters
- L is the length of the threaded portion in millimeters
- D is the diameter of the tap used in millimeters
- r.p.m is the revolutions per minute of the job.
