Milling Machine Definition: The milling machine is a type of machine which removes the material from the workpiece by feeding the work past a rotating multipoint cutter.The metal removal rate is higher very high as the cutter has a high speed and many cutting edges. It is the most important machine in the tool room as nearly all the …

Therefore, this paper will focus solely on the design of a low-cost CNC milling machine using Arduino technology and stepper motors. The rest of the contribution is organized as follows: in Sect. 2 the design method; in Sect. 3 the selection formulation; Sect. 4 describes the results; and finally the conclusions are presented in Sect. 5 .

The limitations of significant tool wear and tool breakage of commercially available fluted micro-end mill tools often lead to ineffective and inefficient manufacturing, while surface quality and geometric dimensions remain unacceptably poor. This is especially true for machining of difficult-to-machine (DTM) materials, such as super …

Therefore, the material selection is the primitive factor in machine tool design. Generally, metallic structures possesses low damping performance due to lower damping capacity [28]. Cast iron has ...
