Yes, a simple machine can create friction, and friction can create heat. You are converting mechanical energy to thermal energy.
The smaller amount of friction a machine has, the more efficient it becomes.
(Output work) + (friction losses) = (input work) on any type of machine.

Some machines need friction to operate. Brakes, grinders, traction wheels, and others all rely on friction to work. In other cases, friction is bad. electric and fuel-fired powerplants for example, are all designed so as to minimize friction. That's why the lubricant industry exists!
(Output work) + (friction losses) = (input work) on any type of machine.
You use simple machines to make work (moving things) easier.
Noise is produced in machines due to friction.

when machines are used
They use machines so people don't have to work as hard.
