Threading help

For small lead threads say < .125" I never use the compound just plunge straight in with the cross slide, this has worked very well for the last 30+ years working in a machine shop.

CNC lathes may be programmed with an approach angle that behaves like a compound, I often do not set this value so the tool moves straight in like a cross slide, have never noticed a difference in threading performance at small leads.
