Surface finish (Also called sometimes surface roughness) is a numeric representation of a surface's "smoothness". There are 3 main ways to acquire the surface roughness value: Mechanical Scan: The most common method is to scan the surface with a needle that records the micro "Hills " and "valleys" along a linear section. The ...

WhatsApp: +86 18838072829Inserts with a parallel land (BS) are capable to make a flat surface. Depending on the axial tolerance and runout of the cutter, the insert with the lowest position will create the milling surface finish. To generate the best milling surface finish, it is important to ensure that the feed per revolution ( fn = fz x zn) is less than 80% of BS.
WhatsApp: +86 18838072829Surface roughness is a calculation of the relative smoothness of a surface's profile. The numeric parameter Ra. The Ra surface finish chart shows the arithmetic average of surface heights measured across a surface. As already mentioned, there are three basic components of a surface, roughness, waviness, and lay.

WhatsApp: +86 18838072829Keep a low cut width (or cut depth if you're talking the floor of a pocket or surfacing with a Face Mill) and do a separate finish pass. The depth of cut has to be larger than the chip load, or you can get rubbing. Usually something like 23x chip load will be right for the finish pass.

WhatsApp: +86 18838072829The end result is end mills will take longer and they will have a much less fine surface finish. Second, solid end mills are more expensive than indexable tooling. Conclusion. I keep a 2″ diameter 90 degree facemill in my shop as well as a 3″ Glacern FM45 45 degree face mill. The FM45 sees a lot more use for sure.
WhatsApp: +86 18838072829When machining freeform surfaces with a ballend milling tool, the working tool diameter is constantly changing even if the tool path is constant. The reason is that the surface normal of the milled surface is continuously changing along the milling path. When the working diameter is changing, the cutting parameters also change. This variation effects the roughness homogeneity of the smoothed ...
