The relative motion of the tool or cutter with respect to the workpiece is the major difference between a drill press and a milling machine. A drill press is limited to only up and down motion (Z-Axis). It can cut holes into the workpiece but it is unable to cut the faces of a workpiece. So work output is limited.
Face Milling Milling. In the operation of face milling, the axis of the milling cutter remains perpendicular to the surface being milled. In this case cutting action is done by cutting edges of both sides (end and outside) periphery of the milling cutter. Depending upon the relative geometry of workpiece and milling cutter face milling is ...
Milling cutters can cut in two directions, conventional (sometimes known as up milling) or climb (sometimes known as down milling). In conventional milling, milling cutter rotates against the direction of feed of workpiece, the chip thickness is zero at the entrance of cutting tooth and maximum at tooth exit.
The main differences between the Lathe machine and Milling machine are: There is a single point cutting tool in the Lathe machine whereas there is a multipoint cutting tool in the Milling machine. In Lathe machine, job piece rotates whereas in …
In up milling, cutting forces vary from a minimum at the beginning to a maximum at the end. Whereas in the down milling, the cutting force varies as a maximum at the beginning and minimum at the end. In up milling, The force of cutting tends to lift up the work since it is directed upwards. Hence fixturing is difficult.
Up and Down Milling. Up milling:-. In up milling, cutter rotates against the direction of table feed. Chip load on teeth (or uncut chip thickness) increases gradually from zero at the point of engagement to maximum at the point of disengagement. Here, tooth experience gradual loading as contact starts with a line.
