Abstract:
Motivations in favour of milling “against
feed direction” in opposition to milling
“in feed direction” are known. They
are justified by studies (Alexandru ş.a.
1969, Tăran 1971, Pahlitzsch
1977, Dogaru 1981, Zerizer 1988, Juan 1992, Ispas
1997) concerning the modality of chip formation,
with implications on the dynamics of chip detachment,
quality of processed surfaces, geometry of cinematic
undulations, control of the feed motion etc. Unfortunately,
no comparative studies of the energy consumption
during the two milling procedures for absolutely
identical conditions (wooden material, machine-tool,
tool, devices, cutting conditions) have been performed
(or, better said, no such references are available).
It is exactly this gap in reference literature
to be partly covered by the present paper.
Key words:wood
milling, milling “against the feed”,
milling “in feed direction”, energy
consumption. |
