Ball Nose Milling Strategy Guide

2017-6-26 · Ball Nose Milling Without a Tilt Angle. Ball nose end mills are ideal for machining 3-dimensional contour shapes typically found in the mold and die industry, the manufacturing of turbine blades, and fulfilling general part radius requirements.To properly employ a ball nose end mill (with no tilt angle) and gain the optimal tool life and part finish, follow the 2-step process below (see Figure 1).

Determining Depth of Cut

 · 1) using logic statements (IF THEN OTHERWISE) to override formula on depth of cut increase with end mill shorter than 1.5 times diameter 2) feed and chip thickness max limit currently set at 0.015" chip thickness 3) DOC limit even when Machinabilty rating of aluminum or plastic is used to limit max recommended depth of cut to 1.5 times diameter.

Simulation of Ball-nose End Milling Operations

2017-9-18 · with a ball-nose end mill. 1. INTRODUCTION Ball-nose end mills are used for the generation of sculptured surfaces, such as those found in dies and molds. The analysis and optimization of NC programs for ball-nose end milling can be approached with continuous or discrete geometric representation of the workpiece geometry.
