AI Technical Summary
Technical Problem
Existing tap tools experience bending stress and reduced dimensional accuracy due to cutting resistance, leading to increased machining time and limited effectiveness in synchronous tap machining.
Method used
A tap tool design with a co-axially aligned axis of rotation and central axis, featuring a thread section, pad sections, and a non-engagement section, allowing for high-speed retraction without rotation, and supporting cutting resistance via pad sections to minimize deflection.
Benefits of technology
The design enables high-speed retraction, reducing machining time by approximately 40% while maintaining machining accuracy, and minimizing deflection and cutting resistance effects.
