The surface finish in milling is found to be influenced in varying amounts by a number of factors, such as cutting speed
, feed rate, depth of cut, material characteristics, tool geometry, workpiece deflection, stability and stiffness of the machine tool--cutting tool--workpiece system, built-up edge, cutting fluid, etc.
Tool coating, cutting speed
, and the interaction of cutting speed
with tool coating were also effective but less significant.
The machine's rpm is not a good indicator of the cutting speed
In terms of cutting speed
, the carbide tipped blade cuts at 1200-1300 sfm, compared to 700 for carbon steel blades.
A considerable number of studies have researched the effects of the cutting speed
, feed, depth of cut, nose radius and other factors on the surface roughness.
As shown in figure 3, the results using higher beam quality are significantly faster than the standard--for 2mm stainless steel the cutting speed
is 45 per cent faster, and for 4mm the speed is 25 per cent faster.
Input parameters for this model are reamer geometry, feed rate, cutting speed
, initial hole geometry, process faults including parallel offset runout, spindle tilt, respective locating angles and tool/hole axis misalignment.
In this study, the cutting force and surface roughness were considered as the test indexes, and cutting speed
, feed rate and cutting depth were the primary factors.
In general, the thrust and torque conditions will mainly depend on the manufacturing conditions employed, such as: feed, cutting speed
, tool geometry, machine and cutting tool rigidity, etc.
Gong, Li, and Ehmann (2005) studied the dynamics of initial penetration in drilling with twist drills and verified that cutting speed
at the chisel edge is small when compared to the main cutting edges.
is arrogated as most important parameter which leads to increase in temperature by increasing cutting speed
