Knee Milling Machines are used for cutting the internal or external material of a workpiece by way of a rotating milling cutter.These machines are used for milling, drilling, tapping, facing, keyway, pocketing and slotting operations. Knee milling machines are engineered with a T-slotted worktable that has three T-slots used to clamp material to be machined.
Milling Machine The milling machine has always been one of the most versatile machine tools used in industry (Fig. 5). Operations such as milling, contouring, gear cutting, drilling, boring, and reaming are only a few of the many operations which can be performed on a milling machine. The milling machine can be programmed on three axes:
tive for machine operators to understand the decision-making process for selecting suitable cutting tools for each job. This course curriculum contains 16-hours of material for instructors to get their students ready to make basic decisions about which tools are suitable for standard milling operations.
Milling is the process of machining using rotary cutters to remove material by advancing a cutter into a workpiece. This may be done varying direction on one or several axes, cutter head speed, and pressure. Milling covers a wide variety of different operations and machines, on scales from small individual parts to large, heavy-duty gang milling operations.
SAFETY RULES & BASICS FOR MILLING MACHINES Milling machines are used to cut metal to drill, slot, and removal metal in the horizontal plane. The rotating bit is extremely sharp and requires special safety precautions while being used. Be sure to always follow good safety practices in the shop as described in General Robotics Safety Rules.
