Drill wear monitoring based on current signals
This paper presents a simple method for on-line wear state monitoring and tool replacement decision-making using spindle motor and feed motor current signals in drilling. In the paper, the effects of tool wear as well as cutting parameters on the cutting current signals are analyzed. The models on the relationship between the current signals and the cutting parameters are established under diff...
متن کاملSingle Piezo-Actuator Rotary-Hammering (SPaRH) Drill
The search for present or past life in the Universe is one of the most important objectives of NASA’s exploration missions. Drills for subsurface sampling of rocks, ice and permafrost are an essential tool for astrobiology studies on other planets. Increasingly, it is recognized that drilling via a combination of rotation and hammering offers an efficient and effective rapid penetration mechani...
متن کاملStochastic Drill-string Dynamics with Uncertainty on the Imposed Speed and on the Bit-rock Parameters
A drill string is a slender structure with nonlinear dynamics; it is an equipment used in the oil industry to drill rock in the search of oil and gas. The aim of this paper is to model the uncertainties related to the speed imposed at the top and uncertainties related to the bit-rock parameters, and to investigate how these uncertainties propagate throughout the system. The continuum system is ...
متن کاملA Multiclassifier Approach for Drill Wear Prediction_adiez
Classification methods have been widely used during last years in order to predict patterns and trends of interest in data. In present paper, a multiclassifier approach that combines the output of some of the most popular data mining algorithms is shown. The approach is based on voting criteria, by estimating the confidence distributions of each algorithm individually and combining them accordi...
متن کاملThermally Stable Diamond Drill Bit Cutters
Superadiabatic Partial Oxidation for Hydrogen and Sulfur Production from Hydrogen Sulfide The Gas Technology Institute has been investigating superadiabatic partial oxidation concepts to not only develop novel, cost-effective processes to recover hydrogen and sulfur from hydrogen sulfide, but also produce hydrogen from natural gas and other liquid hydrocarbons, and gasify solid feedstocks, incl...
