In order to press the fabric with the presser foot, the sewing machine Brother DB2-B737-915 MarkII has an helicoidally
It is obvious that a safe boundary between the two streams of different senses does not exist, but certainly they are mutual influence--surely negative: the ascendant helicoidally
stream will drive a main part of the thin faction in over trickling.
The transitory regime produced by coupling the cutting thread faze, produces a declination of the tool from the helicoidally trajectory, phenomenon that modifies the pitch of the tread.
the beginning of the helicoidally trajectory is strongly affected, but, due to the low transitory regime, (0,2 seconds), the tool enters again on the helicoidally trajectory before beginning to cut;
Basically, a 10 tones mass can be weighted and monitored by a helicoidally
arc subjected to a force of 200 N, 250 times smaller that the external load.
Normal medial tangential helicoidally
machining The medial helicoidally
tangential trajectory is given by two trajectories: tool centre trajectory LS1 and tool holder trajectory LS2, which are perpendicular on feed vector.
shaped thrust pad were taken into account due to the simplicity of the lubricant shape.
