Simulation of the BTA deep-hole drilling process
Production Engineering, 2009The dynamic disturbances of the deep-hole drilling process pose a great challenge. Especially spiralling, which causes holes with several lobes, can damage the workpiece irreparably. The causes for spiralling are not well explored yet, and it is important to analyze which conditions and process parameters can cause the spiralling. This article presents

Experimental Study of TC4 Titanium Alloy Deep Hole Drilling Based on Machine-Clamped Deep Hole Drill
2020 3rd International Conference on Electron Device and Mechanical Engineering (ICEDME), 2020There are many deep hole processing methods for TC4 titanium alloy, but it is a blank to drill with a mahine-clamped deep hole drill, so we have carried out some experi--mental studies. Using different spindle speed and feed in the test process of chip morphology and chip removal condition respectively and drill bit, the abrasion of guide block is ...

Forces in Deep-Hole Bone Drilling
Volume 1: Additive Manufacturing; Manufacturing Equipment and Systems; Bio and Sustainable Manufacturing, 2019Abstract Deep-hole bone drilling is performed in many surgical implantation procedures. Unlike bone drilling of shallow holes (commonly 5 to 7 mm in depth), deep-hole bone drilling requires a larger hole depth (i.e., up to a depth of approximately 35 mm in cochlear implantation) using a high ratio of the length to diameter of the drill ...

Ecological Deep Hole Drilling by Novel Coated and Designed Drill
Key Engineering Materials, 2007Ecological deep hole drilling is proposed in this paper. The ecological drilling means a cutting without coolant or minimum quantity lubrication (MQL). Under a cutting condition with a small amount of lubrication, the drills should be designed availably to control heat generation during cutting.

Structural Optimization of Drilling Bed for Deep Hole Drilling Machine
Applied Mechanics and Materials, 2014Taking the drilling bed of Z8016 deep hole drilling machine as the research object, a modal analysis of drilling bed structure is performed by ANSYS software. Assuming that the low-order natural frequencies basically remain unchanged, the structure of the drilling bed is analyzed and modified so as to decrease its weight.

HOLE QUALITY IN DEEP HOLE DRILLING
Materials and Manufacturing Processes, 2001Deep hole drilling represents the most economical method of hole producing with length-to-diameter ratios ≥5. The objective of this study was to ascertain the effect of machining parameters on hole quality produced by the deep hole machining process and to develop a better understanding of the effect of these process parameters on the hole quality ...
