Features of Upcut
The upcut starts with a chip thickness of 0 and thickens little by little. Although it tends to wear quickly by scraping while scraping the workpiece surface, a good finish surface can be obtained.
Features of climb cut
climb cut starts with a thicker chip thickness and gradually becomes thinner. It is a processing method that has a good chamfer of cutting edges and is less likely to cause vibration and vibration. It also tends to wear less and is better in terms of tool tool life .
| What is Upcut? | What is climb cut ? |
| The chip thickness starts at "0" and gradually thickens. ・Scrape while rubbing the surface to be machined. ・The burden on the cutting edge increases. ・Wears out quickly ・Vibration is likely to occur. ・Good finishing surface can be obtained. |
At first, the chip thickness is thick, and gradually it becomes thinner ・Good chamfer of cutting edges ・Less wear and tear ・Less vibration ・Effective for workpiece materials that are prone to work hardening |

In OSG's ThreadPro program creation application for thread mills, climb cut is input as the default value, which can aim for stable machining with little vibration.
minor diameter Right-hand thread internal thread the tool moves up from the bottom of the hole to hole entrance , but if you change this to an upcut, the tool moves down from hole entrance to the bottom of the hole. Especially in the case of a stop hole, be careful not to disturb chips at the bottom of the hole.
