Helical Interpolation

Definition

Helical interpolation is a machining technique used to create helical features, like threads or grooves, on a workpiece by simultaneously moving the cutting tool along a circular path while also advancing it linearly. This method allows for precise and efficient manufacturing of complex geometries, making it especially useful in milling, turning, and drilling operations where helical shapes are needed. It enables the production of intricate designs that would be challenging to achieve with traditional machining methods.
