NOTE
G71 turning cycle is used for rough-material removal from a CNC lathe component. G71 turning cycle makes large diameter cutting easy. Cutting can be done in simple straight line or a complex contour can also be machined very easily.
In this program G71 turning cycle will keep repeating the contour given inside P=7&Q=11 that is the G71 turning cycle will work between N07 to N11

An aluminium component is to be machined on a vertical CNC milling machine. The original stock material is a flat piece having dimensions of 125 x 105 x 10 mm3. The top and bottom surfaces of the finished component are not machined in this operation. All other surfaces and features need to be machined. The finished shape has three Æ20-mm holes machined right through and a slot is machined to a depth of 5 mm. The outside dimensions of the...
