When milling 45 steel with 6mm carbide end mills, the amount of cutting should be determined and how to set the cutting parameters
Generally cutting speed of 150 meters / minute, feed 0.1 ~ 0.3mm/t, cutting depth can be 3mm.
The speed is about 800r/min, the amount of feed at 3 100mm/min cutter blade, two edged 70 mm/min, depth 3-5mm;Cutting is a general term for various cutting motion parameters, including cutting speed, feed rate and cutting depth (cutting depth). The tool life (closely related to the metal cutting principle), which is closely related to the amount of cutting used in a process, is generally divided into two types: the single cost, the lowest economic life and the maximum productivity life. The amount of cutting used by the former is called the minimum cost of cutting. This is usually used; the amount of cutting used in the latter is called the maximum productivity, and the amount of cutting is usually used when the production is critical.1 cutting speed VC refers to the tool cutting edge on the selected point relative to the workpiece to be processed surface in the main moving sideThe instantaneous speed of the unit is M/min.2 feed f the relative displacement between the tool and the workpiece in the direction of feed motion at the main movement of each turn or at each stroke (or unit time). Unit mm/s.3 depth (cutting depth) AP surface to be machined and the machined surface of the vertical distance between the units mm.When the NC machine is machining the workpiece, its cutting parameters are programmed into the program, and under normal circumstances, it will not be changed manually. It is only in the case of cutting or abnormal occurrence that the amount of cutting can be adjusted by changing the tool offset, changing the feed speed by multiplying wheel, or re compiling the program.The main factors affecting the cutting amount of NC machining are the following factors:(1) machine speed;(2) tool specification(3) workpiece size;(4) cutting fluid concentration;
