Investigations into tilt angles and order of cutting sequences for cutting head design of roadheaders
Hekimoğlu, Osman Zeki (Pergamon-Elsevier Science Ltd, 2018)This paper explains optimum arrangement of gauge tools and corner cutting picks for cutting head design of roadheaders. Full-scale simulation of roadheaders cutting heads of practical types with a wide range of tilt angles ... -
A pick force calculation method suggested for tool lacing of mechanical excavators employing drag tools
Hekimoğlu, Osman Zeki (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 ... -
A rational comparison of groove deepening to relief cutting in terms of tool spacing with drag tools
Hekimoğlu, Osman Zeki (TMMOB Maden Muhendisleri Odasi, 2017)This paper mentions a rational comparison between relief cutting and groove deepening for tool lacing design of partial-face cutting machines employed for mechanical excavations of rocks, coal and stones. The comparison ... -
Studies on increasing the performance of chain saw machines for mechanical excavation of marbles and natural stones
Hekimoğlu, Osman Zeki (Pergamon-Elsevier Science Ltd, 2014)Slow cutting rate, tool wear and shallow depth of cuts are important practical issues observed with the commercially available chain saw machines. This paper is concerned with increasing the performance of current chain ... -
Suggested methods for optimum rotative motion of point attack type drag tools in terms of skew angles
Hekimoğlu, Osman Zeki (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 ...
