There are two main reasons metal heats up, direct heat (flame) and friction. If your tool is not sharp enough then essentially the blunt edge you are presenting to the timber is not 'cutting' effectively and is just 'rubbing'. The rubbing, essentially, is 'friction' and causes the steel to heat up. As a side effect the timber also heats up which can cause the timber to check (crack) and distort.
I'd probably ensure that your tools are sharp. If you are using harder types of timber then sharpen frequently. If you're not in a woodturning or wood club, they can assist with the correct sharpening techniques.
Hope this helps.

I agree with everything said above, but on really hard, dry wood and with a good edge, the tip will get hot. Rubbing the bevel at 3000 rpm will cause friction ! Phil
