Top 8 Milling Tools for CNC Cutting
Jun 07, 2018The principles of rotation direction, chip formation, chip load, and milling orientation will travel with you throughout your machinist career. Rotation Direction Every tool – except those designated as left-hand, like a left-handed tap – will rotate in a clockwise direction when viewed looking down at the part from the machine's spindle.

Milling Machines
A milling machine is set up to drill holes in a circular pattern. The variable Bcount gives the number of holes while Diam is the diameter of the drilled circle. The first hole is drilled at an angle Alpha from a reference mark on the circle. Our task is to compute for each hole, the x, y coordinate values where 0, 0 are the coordinates of the circle's center.

Milling Machine: Methods of Milling. Milling Processes
Jun 28, 2009Milling is an important process of manufacturing technology and basically it refers to the removal of metal from the work piece using a tool which has several cutting points and is rotating about its axis. Thus each cutting point removes a little bit of the metal but since there are multiple such points and the tool is rotating at a fast speed, the overall removal is quite brisk.
