Beschreibung
Zusammenfassung:	A method for finishing at least one port within a cylinder of a two-stroke engine, comprising tracing a curvature of an existing port hole for the at least one port using a force sensing tool, wherein forming an engine block for a two-stroke engine, comprising: casting the engine block, wherein the cast engine block includes at least one intake port and at least one exhaust port; rough machining a cylinder of the engine block, wherein at least one of the at least one intake port and the at least one exhaust port is positioned along a wall of the cylinder and both of the at least one intake port and the at least one exhaust port are fluidly coupled to the cylinder; and finishing an edge of at least one of the at least one intake port and the at least one exhaust port to provide a smooth surface. L'invention concerne un procédé de finition d'au moins un orifice à l'intérieur d'un cylindre d'un moteur à deux temps, comprenant le traçage d'une courbure d'une ouverture existante pour ledit orifice à l'aide d'un outil à détection d'effort.
