This article deals with analyzing the existing cutting tools and ways of hole-making
operations. The newly designed tool consists of four false teeth-incisors and the curved …

In this paper, a comprehensive investigation in terms of tool wear/life, chip morphology,
surface roughness/damage, diametric error, burr height, and microstructure is conducted by …

Deep-hole manufacturing is widely applied in the aerospace, transportation, and mineral
mining industry. The axis deviation of deep-hole is a manufacturing challenge, especially in …

In this paper, the BTA deep drilling is analysed experimentally and by modelling. Drilling
tests shows the significant effect of feed rate and the slight effect of cutting speed on the …

The problem of chip breaking and evacuation is the key point of staggered teeth boring and
trepanning association (BTA) drilling. The factors that influence chip breaking with staggered …

In the process of boring and trepanning association (BTA) deep hole drilling, the guide block
plays the role of guiding, balancing the cutting force and extruding and polishing the …
