- Moreover, above 30?the friction angle becomes smaller than the helix angle and the nut is no longer self-locking and the mechanical advantage disappears.
- Using a multiple-form cutter is faster than using a single-form cutter but it is limited to threads with a helix angle less than 3?
- In one variant of form-milling, the single-form cutter is tilted to the helix angle of the thread and then fed radially into the blank.
- In mechanical engineering, a "'helix angle "'is the angle between any helix and an axial line on its right, circular cylinder or cone.
- Where N is the total number of teeth, p is the circular pitch, P _ d is the diametrical pitch, and \ psi is the helix angle for helical gears.
- Similarly, one may construct a double-thread screw provided that the helix angle is the same, and a second thread is cut in the space between the grooves of the first.
- This method of gear cutting is based on the principle that any two gears will mesh if they are of the same pitch, proper helix angle, and proper tooth depth and thickness.
- A worm gear is a species of helical gear, but its helix angle is usually somewhat large ( close to 90 degrees ) and its body is usually fairly long in the axial direction.
- Another variant of form-milling involves holding the cutter's axis orthogonally ( no canting to the thread's helix angle ) and feeding the cutter in a toolpath that will generate the thread.
- As the slot has a helix angle of about 35? any axial movement of the outer shaft causes the segment to rotate, exposing more or less of the nose constant radius and thus changing the duration.
- Influencing variables for the maximum winding speed are the needle stroke, the rotation angle of the stator ( number of poles ), the wire diameter and the groove channel width and the helix angle of the angularly grooved stators.
- The helix angle has its origin in the width of the segment used ( normally about ) and the 20-degree region of constant radius on the nose of the lobe ( this usually measures about 7 mm in circumference ).
- Quite commonly, helical gears are used with the helix angle of one having the negative of the helix angle of the other; such a pair might also be referred to as having a right-handed helix and a left-handed helix of equal angles.

- For shafts " crossed " at right angles, the helix angles are of the same hand because they must add to 90 degrees . ( This is the case with the gears in the illustration above : they mesh correctly in the crossed configuration : for the parallel configuration, one of the helix angles should be reversed.

- The maximum relative velocity is kept as low as possible by careful control of pitch to allow the blades to have large helix angles; thin blade sections are used and the blades are swept back in a scimitar shape ( Scimitar propeller ); a large number of blades are used to reduce work per blade and so circulation strength; contra-rotation is used.
- The toolpath is achieved either using helical interpolation ( which is circular interpolation in one plane [ typically XY ] with simultaneous linear interpolation along a third axis [ typically Z ]; the CNC control model must be one that supports using the third axis ) The cutter geometry reflects the thread pitch but not its lead; the lead ( thread helix angle ) is determined by the toolpath.
