Learn MoreA vertical milling machine is typically a precision tool that's useful in fabrication and shaping by the removal of stock often from metallic workpieces. Based on the material and tooling, the mill can also machine plastics, as well as other materials. There are three main methods of operating mill controls: manually, computer numerical
Learn MoreThe Metal Removal Rate is calculated by multiplying the area of the chip's cross-section by the linear velocity in the direction perpendicular to it. Let's look at a simple milling application as an example: The chip Area is A p x A e. The Perpendicular Speed is the table feed (Vf). (In a full plunging operation, the chip area would be π x
Learn MoreMaterial removal rate (MRR) is the amount of material removed per time unit (usually per minute) when performing machining operations such as using a lathe or milling more material removed per minute, the higher the material removal rate. The MRR is a single number that enables you to do this.
Learn MoreAnother type of toolpath that can raise MRR's is called Plunge Milling. Plunge Milling a Pocket – Image courtesy of BobCAD Plunge milling relies on the idea that machines are more rigid in the vertical direction. So, if the limiting factor is rigidity, you can potentially overcome that and increase MRR's by using plunge milling.
