Face Milling PVC - Practical Machinist

Coming from metal, we thought PVC face milling was a piece of cake. Now we are here: we face milled a 12x5 inch piece (2" thick) and the result is literally awful. We think we have learned the following lessons so far: 1. sharpness of endmill seems important. 2. rigidity of setup seems important.

CNC Face Milling of Straight and Spiral Bevel Gears

Standard face mill cutters for spiral bevel gears range from 1" to well above 15", in variable steps. A practical upper limit for a 5-axis CNC machine appears around 6" because of cutter mass and required spindle torque, which allows the face milling of spiral bevel gears up to around 6mm module. For larger mod -

The first milling operation is face milling to make one side of the plate flat and smooth to accept the components that are to be attached. This is accomplished in one setup on a large milling machine in the mill department. The second milling requires a separate setup, and this operation makes the edges of the casting smooth and straight.

5 Common CNC Machining Problems, Errors and Solutions ...

Here we present the most common CNC machining problems. 1. Improper Tools or Settings. Improper cutting tool, the tool tip is damaged and not sharp, or improper cutting coolant/lube, these will cause the poor surface finish on the part, and even leave cutter mark on the material, which speeds up the tool wear at the same time.

Flatness issues milling 304 stainless - Practical Machinist

I'm milling .250x3x8 304SS plates to .200" thick and they're not coming out flat, especially once the inserts start to wear. I'm seeing .020-.030" variation in thickness on some of them. Is this just the nature of 304? Would 303 be much better for this? I'm going about 200sfm and .005IPT on a 5in face mill.

Face-off: Face Hobbing vs. Face Milling | Gear Solutions ...

The continuous indexing method, referred to as "face hobbing" (FH), caused a small revolution in North America a few years ago, in conjunction with dry-cutting. Until then, the classic five-cut method had been state of the art for many decades. This is a single-indexing method, which cuts one after the other gaps in the gear blank.
