Porankiewicz, Boleslaw - Axelsson, Bengt - Anders Grönlund, Anders - Marklund, Birger

Formato:	info:eu-repo/semantics/article, info:eu-repo/semantics/publishedVersion
Enlaces:	In this work the multi-factor, non-linear dependencies between main (tangential) FC (N) and normal (radial) FN (N) cutting forces and eight machining parameters by sawing simulation of wood of Pinus sylvestris L. were evaluated. The relationships are graphically illustrated and…
