Good Practices for Milling Aluminum Aluminum is one of the most machinable and affordable metals available, which is exactly why it’s found in almost every machine shop. From prototypes to high-volume production, aluminum jobs are everywhere. In this post, I’ll walk through good practices for milling aluminum, focusing on tool… Read More »How to Milling Aluminum Successfully
Cost per cutting edge – why it is lower for a negative insert A negative insert, like the VNMG insert in the picture, has a zero relief angle. Both faces of the insert are therefore the same, and you get cutting edges on both. The cost of a positive and… Read More »Insert Economy or How to Make More Parts With Lower Cost for Tools
Reducing Radial Forces in CNC Turning: A Practical Guide Very often in our daily work as programmers, technologists, setters, and CNC lathe operators, we encounter problems related to radial cutting forces. These forces act perpendicular to the workpiece axis and can significantly affect the cylindricity, parallelism, and overall dimensional accuracy… Read More »CNC Turning – Reducing Radial Cutting Force
We decide the depth of cut on the basis of an arbitrary thumb rule. E.g., in rough turning we’ll always use a depth of cut of 3 mm. Why not 4, 5 or 6 ? Nobody knows. Just a bad thumb rule that makes your lathe a elephant. Here’s a… Read More »Maximum depth of cut in rough turning, based on turning insert shapes
