Types of tool offset that ensure Understanding Lathe Tool Nose Radius Selection Choosing the right lathe tool nose radius can make a big difference in machining. The G41 and G42 commands are used to activate tool nose radius compen ation. The purpose of the surface roughness application is to enable the user to calculate the correct amount of lathe feed or ball nose cutter stepover to Shown as the figure below, corner radius is formed by crossed line major cutting edge and side cutting edge, which is also named as edge radius. How to calculate Nose Radius of Tool from Surface Finish Constraint using this online calculator? To use this online calculator for Nose Radius of Tool from Surface Finish Constraint, enter In order to avoid catastrophic failure of tool tip, a tiny rounding or small radius is provided there, which is known as nose radius. A larger nose radius results This calculator provides an approximation of the impact of tool nose radius on surface finish and corner radius during machining of small features. Actual results may vary The class Calculations for Programming the Lathe provides an in-depth explanation of various calculations necessary to determine tool positions on the lathe or turning center.
