1. Incomplete thread portion
At the start and end of an axis feed, an axis drive
servo motor is automatically accelerated or
decelerated. Consequently, inaccurate thread
leads are generated where thread cutting starts
and ends. These areas are referred to as
incomplete thread portions.
To explain incomplete thread portions more
completely, thread cutting from point A to point B
is used as an example.
1. Porción de filete incompleto
Al inicio y final del avance de un eje, un servomotor
accionado por el eje acelera o desacelera
automáticamente. Como consecuencia, se generan
guías de filete imprecisas cuando se inicia y finaliza el
fileteado. Estas áreas se denominan porciones de filete
incompleto.
Para explicar más ampliamente porciones de filete
incompleto, el fileteado del punto A al punto B se utiliza
como ejemplo.
When thread cutting starts from point A, axis feed
is accelerated causing incomplete thread portion
for L
1
. Similarly, incomplete thread portion is
generated for L
2
because axis feed is
decelerated at point B.
Therefore, to obtain the thread length of L, it is
necessary to carry out thread cutting in the range
of (L
1
+ L + L
2
).
Cuando se inicia el fileteado desde el punto A, el avance
del eje acelera, causando una porción de filete
incompleto para L
1
. Del mismo modo, se genera una
porción de filete incompleto para L
2
porque el avance
del eje se decelera en el punto B.
Por consiguiente, para obtener la longitud del filete de L,
será necesario realizar un fileteado en el intervalo de
(L
1
+ L + L
2
).
