### Surface Roughness Chart: Understanding Surface Finishes ...

2021-2-25 · Surface finish refers to the process of altering a metal’s surface that involves removing, adding, or reshaping. It is a measure of the complete texture of a product’s surface that is defined by three characteristics of surface roughness, waviness, and lay. The surface roughness is the measure of the total spaced irregularities on the surface.

2021-3-1 · This seems like it would be an easy thing to find the answer for but after many hours of searching I cannot come up with it. I can easily calculate the cusp height for machining a surface with a ball endmill and a given stepover but I cannot find a formula for calculating the theoretical surface finish in Ra.

### Surface Finish Calculation Time? - Industrial Forum ...

2011-2-21 · My finish toolpath is a .020 ballnose, surface finish flowline, .001 tolerance with filter set to output all arc moves in x/y, and a .0005 stepover. So far, it's been rocking out over 6 hours. The HST are the only ones that multithread and that leaves Mastercam frozen and, pretty much my whole computer almost worthless.

### stepover? - Vectric Customer

2011-12-5 · The stepover is how far the bit will move over before making the next pass. You can set this as a percentage the bit diameter or a set distance. Used in a pocketing toolpath. The Pass depth depends on what you are cutting. A rule of thumb would 1.5 times the diameter of your bit. Ryan Patterson.

### Fablab Feeds and Speeds Calculator

Cutting generates a lot of heat, making oil based coolant preferable. Many machining spindles require 2000 rpm or more, to provide adequate cutting torque, which means that you have to use relatively small diameter end mills in order to end up with surface speeds this low. If not using coolant, then max surface speed is 50 ft/min. Insulation foam

### Feeds & speeds - Shapeoko CNC A to Z

The larger the stepover, the larger the force on the endmill. Cutting passes with a small stepover are better for surface finish quality, while passes with large stepover obviously reduce overall cutting time since fewer passes are required to cut a given amount of material. And then depth of cut will also come in the picture (more on this later).

### 3D surface finishes - Vectric Customer

2016-12-14 · Often I will skip the roughing pass and cut 3D using only a finish pass. With an 8% stepover the side of a 1/16" bit is only removing 0.005" of material so it is possible to carve at full 1" depth. It is important to watch the preview. If the bit jumps to a new area it may plunge at full depth and break the bit.

### SURFACE FINISH CONTOUR START POINT - Industrial

2018-4-3 · Flowline, Surface Finish Contour and Blend will all do undercut surfaces, but ONLY if you use a cutter capable of machining undecuts, such as wheel cutter or lollipop. Waterline does NOT support undercut machining. The fact that you got good toolpath "inside" using SFC but not on the "outside" does indicate undercut surfaces.
