Which side should you mill on?
Which direction should an end mill spin?
A tool rotates clockwise is called “Right cutting edge”. A tool rotates counter-clockwise is called “Left cutting edge”. Ordinary end mills are “Right cutting edge” and “Left cutting edge” are very rare. Direction of chip evacuation differs in direction of Helix.
Which way is climb milling?
There are two distinct ways to cut materials when milling: Conventional Milling (Up) and Climb Milling (Down). The difference between these two techniques is the relationship of the rotation of the cutter to the direction of feed.
Which milling direction produces the best surface finish?
Climb milling produces excellent surface finishes and works best in most cases. The cutter is revolving in the same direction as the table feed, meeting the workpiece at maximum thickness, producing the largest chips first.
Do end mills cut on the side?
The Spiral-shaped cutting edges on the side of the end mill are called flutes. Flutes provide an empty path for the cutting chips to escape from when the end mill is rotating in a workpiece. End Mills have either 2, 3 or 4 flutes per bit.
Which is the best depth of cut for better surface finish?
For finishing, select cutting depths of less than one third of the nose radius. To ensure a good surface finish, use a special wiper insert that has a modified nose radius with larger corners to wipe the surface smooth. This will allow you to cut at a faster feed rate.
Which of the following has the largest effect on the tool life?
Feed rate has the most significant effect on tool life followed by spindle speed and depth of cut. published works on metal cutting has regarded these three parameters as having the greatest influence on tool wear and tool life.
What is the unit of cutting speed?
The cutting speed of a tool is expressed in surface feet per minute (sfm) or surface meters per minute (m/min.). Similar to mph for a car, sfm is the linear distance a cutting tool travels per minute.
