This is an excellent video that most home gamers need to see. I know this stuff already from my day job. Rather then use the original variable descriptions for the formula I use my own "speed=(surface foot x 12)/(pie x cut diameter)" . I work in imperial obviously. One factor you didn't get into as deep as you could have was material hardness in the same given alloy. Example 316 might be 30 RC or 40 RC depending on the heat treatment. Which is a world of difference of the surface foot you can run. Also if you are running coolant or not. Another factor affecting the surface foot you can run (primarily affects lathe) is chip formation. Good chip formation ( c's and 6's) will heatsink the cutter and work piece and allow a higher surface foot. Depth of cut also plays into it. My best recommendation is start at 70% of the speed and feed you calculated and work up from there. You also have to decide which is more important to you cutter life or cycle time. At my day job time is king in my home shop it's cutter life.-cheers

Brilliant comment, I learned a lot from that. Really appreciate it man. I’m just planning a feeds vid so stay tuned!

There was some things I forgot to mention. There are some exotic materials that by the time you get what should be perfect chip formation you are pushing the insert too hard and it will fracture. Feeds are a lot harder to get dialed in on a manuals. I ran a material (on a lathe) before that .0083" was the goldy locks feed. .008" was too stringy .009" fractured. Most people will probably never run into stuff like that but in the CNC world sometimes you have to use that extra decimal place on you feed. When you do your feeds video please cover feed per tooth. I believe a decent number of people in the community don't fully understand it. -cheers

To be honest, the quality of information you've given in your comments is so good that I'm thinking of doing Friday's video just on the points you have raised! Thanks again really helpful.
