2. When there is a inclined angle between the tool axial line and the machined surface, the recommended
cutting speed should be multiplied by a factor in the follow table to obtain the cutting speed used for
programming
Unter Berücksichtigung des Neigungswinkels, (Werkzeugachse / bearbeitenden Oberfläche) erhalten Sie die
empfohlene Schnittgeschwindigkeit durch in der Tabelle angegeben Multiplikator.
