Chip load is the maximum load a cutting edge can withstand without yielding. Specified in mm/tooth or Inch per tooth units. Depends only on cutting edge geometry and workpiece material. Independent of application conditions like speed or depth of cut

Modern industry uses hundreds of metal machine tools ranging from bench to production machines. Seven main categories: turning machines, shapers/planers, drilling, milling, grinding, saws, and presses
Machining time is calculated as length divided by feed rate multiplied by RPM. Formula includes length, feed rate, RPM, cutting speed, and tool diameter
Milling removes material using rotary cutters by advancing them into workpieces. Process involves multiple small cuts performed at different speeds and feeds. Material is removed through shear deformation, forming chips
