Machining sequence for thread cutting
Main machining Submachining Location Execution
Thread cutting Contour analysis:
Determining the "Thread" form elements.
Sequence : First outside, then inside machining; the elements are
then machined according to the sequence of geometrical
definition.
All – Machining cylindric (longitudinal), tapered and transverse threads
on the outside and inside of a contour.
All Outside Machining cylindric (longitudinal), tapered and transverse threads
on the outside of a contour.
All Inside Machining cylindric (longitudinal), tapered and transverse threads
on the inside of a contour.
Cylinder – Machining outside and inside threads
Cylinder Outside Machining cylindric outside threads.
Cylinder Inside Machining cylindric inside thread
Transverse – Machining transverse threads on the outside and inside of the
contour
Transverse Outside Machining transverse threads on the outside.
