The mean value is selected: f = 0.3 mm Relationship between feed and feedrate: The constant feed f and the respective speed n yield the feedrate: Vc = 180 m/min Vf = f * n Vc = 180 m/min d2 = 80 mm d2 = 20 mm n2 710 rpm n2 2800 rpm ≈ ≈ Vf2 710 rpm * 0.3 mm Vf2 2800 rpm * 0.3 mm ≈ ≈ Vf2 210 mm/min Vf2 840 mm/min ≈ ≈ Since the speed is different, the feedrate also differs for the various diameters, despite having the same feed. Effective setup In this section, you will learn how to create the tools required for the examples in the following sections. Furthermore, the offset of the tool lengths and the setting of the workpiece zero is explained with examples. Tool management ShopTurn offers three lists for tool management: Tool list ● Tool wear list ● Magazine list ● Tool list The tool list displays all parameters and functions required to create and set up the tools. Figure 5-1 Example of tool list
