The mill may sometimes leak a small amount of flour when milling on the 'fine' setting (10:00 – 11:00 O'clock) (lots of air and little flour blowing into the bowl). Try milling a canister of flour at a 12:00 – 2:00 o'clock setting to see if it makes a difference.

Groove or slot milling - Coromant

Groove or slot milling. Groove or slot milling is an operation in which side and face milling is often preferred to end milling. Slots or grooves can be short or long, closed or open, straight or non-straight, deep or shallow, wide or narrow. Tool selection is normally determined by the width and depth of the groove and, to some extent, length.

Workholding – use of vices | john f's workshop

Similarly the workpiece is raised up so the end mill will not touch the bottom of the vice. After the first three surfaces have been cut the workpiece is turned over and rotated through 90° The only assumption, given the workpiece is firmly held down parallel to the bottom of the vice, is that the bottom is flat and parallel to the milling table.

The Anatomy of an End Mill - In The Loupe

The overall reach of an end mill, or length below shank (LBS), is a dimension that describes the necked length of reached tools. It is measured from the start of the necked portion to the bottom of the cutting end of the tool. The neck relief allows space for chip evacuation and prevents the shank from rubbing in deep- pocket milling applications.

10 Milling Toolpaths for Your First 2D CNC Machining ...

CNC Milling Toolpaths at a Glance. CNC milling toolpaths are typically categorized as 2D, 3D, 4-axis, and 5-axis. However, the term 2D is a bit misleading since this toolpath uses the Z-axis to position a tool for depth. For example, in the image below, we have a prismatic part whose features all reside at various heights on the XY plane.
