What is 'chip load' in the context of lathe operations, and why is it important?

Chip load is the amount of material that a cutting tool removes per revolution. It's important for heat dissipation and preventing tool wear.

According to the video, what is the consequence of using excessively high RPMs with a feed rate that is too slow?

The bit will not cut enough material per revolution, leading to friction, heat buildup, and a dull bit.

A high-pitched sound indicates the feed rate is too low.

A chattering or vibrating sound indicates the feed rate is too high.

Generic charts are often designed for industrial machines with much higher horsepower than desktop machines.

I can calculate appropriate feed rates for lathe operations.

1
Chip load is the amount of material that should be cut with each revolution to remove heat from the bit.
2
If RPMs are too high and the feed rate is too slow, the bit may not cut enough material per revolution, causing heat to remain in the bit and making it dull.
3
When a bit doesn't cut enough material, it rubs against the wood, creating a high-pitched sound and causing more heat.
