Robin,
Quite right - uphill cutting is against the rotation of the cutter, downhill, with the rotation of the cutter. So, for internal, downhill cuts this would be CCW and external cuts would be CW. 'Uphill' and 'downhill' milling are synonymous with 'climb' and 'conventional' milling. Some materials are better cut one way rather than the other. Most good CAM software gives you the option of either.
Ramping, on the other hand, has a number of meanings. In terms of actual cutting it can mean the angle at which the tool approaches the work in the Z axis i.e. it enters the material along a slope. Ramping can also be used to express the rate at which a spindle gets up to speed.
Isn't CNC and the English language wonderful????
