Suggested methods for optimum rotative motion of point attack type drag tools in terms of skew angles
(Taylor & Francis Ltd, 2020)
Rotation of point attack picks in their tool holders is of crucial importance for an efficient performance of machines used for tunnelling and underground excavations of rocks and coal. With current machines, skew angle ...
A pick force calculation method suggested for tool lacing of mechanical excavators employing drag tools
(Taylor & Francis Ltd, 2018)
This paper deals with tool lacing design of partial-face cutting machines employed for mechanical excavations of rocks, coal and stones. A rational comparison between relief cutting and groove deepening was made by simulating ...
