Abstract
Tapping is a very complex machining process, and yet, is widely use to produce internal threads. One of the most common problems in this operation is the feed error, in which the machine has problems to synchronize the tap feed rate and its spindle speed. To investigate this phenomenon, this paper proposed a 3D simplified model of the tapping process and use the finite element method to solve it. The simulations were done only altering the feed in each test, and the maximum thrust force was the output variable analyzed. The results showed that the thrust force changed, even for the smallest variation in the feed. The axial force increases with the feed, and the maximum thrust force increased 92% when the feed increased 10%.
