2003 01 15 nbsp 0183 32 If the infeed per pass is constant which is not recommended then the cutting force and metal removal rate can increase too dramatically from one pass to the next For example when producing a 60 degree thread form using a constant 0 010 inch infeed per pass the second pass removes three times the amount of metal as the first pass

The depth of the last cut through the thread can be controlled with Setting 86 The tool nose angle for the thread is specified in A The value can range from 0 to 120 degrees If A is not used 0 degrees is assumed To reduce chatter while threading use A59 when cutting a 60 degree included thread The F code specifies the feed rate for threading It is always good

The second value defines the angle of runout chamfer at the end of the thread while the third is the angle of the teeth of the thread i e 60 degrees for a

2003 01 15 nbsp 0183 32 Fig 6 This custom thread turning tool is used to machine two separate threads simultaneously on a six spindle lathe The threads used to be machined one at a time The inserts used here were actually intended for a thread milling tool but they are applied here as turning inserts Fig 5 Adjusting the insert s helix angle as in the tilted insert shown at right

2022 03 17 nbsp 0183 32 The Unified screw thread has a 60 degree thread angle with a rounded root and a crest that is flat or rounded As mentioned earlier this is the principal thread form used for screw thread fasteners used in the United States The Unified screw thread system includes six main thread series 1 Unified Coarse UNC 2 Unified Fine UNF 3 Unified Extra Fine UNEF 4

Using the machine s cutter compensation a thread s major diameter can easily be altered to produce precise threads Tool life is increased over common tapping because wear can be compensated when using thread mills No more broken taps When taps break it can be very costly to salvage the work piece If a thread mill breaks during a cut a

Drawing texts and Machine Design handbooks Thread form Thread form is a classification based upon the cross sectional profile of the thread The standard thread form for inch unit threads in U S is the Unified UN thread form This thread form is characterized by a 60 degree thread angle and a flat crest and rounded root Thread series

By dividing the full cutting depth of the thread into smaller cuts the sensitive nose radius of the insert is not overloaded Example By taking 0 23–0 10 mm 0 009–0 004 inch in cutting depth per pass radial infeed the full cutting depth a p and the profile depth of the thread 0 94 mm 0 037 inch is turned on a 1 5 mm 0 06 inch pitch metric thread in 6 passes nap
