En.rgy con.0}mption.of block-cuttin. machin.s.repres.n.s.a major cos. item in.the proces.in. of travertin.s.an. other n.tural s.on.s. Therefore, determin.n. the optimum s.win. con.ition.0}for a particular s.on. is.of major importan.e in.the n.tural s.on.-proces.in. in.us.ry. An.experimen.al s.udy was.carried out utilizin. a fully in.0}rumen.ed block-cutter to in.es.igate the s.win. performan.es.of five differen. types.of travertin. blocks.durin. cuttin. with a circular diamon. s.w. The s.win. tes.s.were performed in.the down.cuttin. mode. Performan.e meas.remen.s.were determin.d by meas.rin. the cuttin. s.eed an. en.rgy con.0}mption. Then. s.ecific en.rgy was.determin.d. The on. main.cuttin. parameter, cuttin. s.eed, was.varied in.the in.es.igation.of optimum cuttin. performan.e. Furthermore, s.me phys.co-mechan.cal properties.of file travertin. blocks.were determin.d in.the laboratory. As.a res.lt, it is.foun. that the en.rgy con.0}mption.（s.ecific en.rgy） of block cuttin. machin.s.is.highly affected by cuttin. s.eed. It is.determin.d that s.ecific en.rgy value us.ally decreas.s.when.cuttin. s.eed in.reas.s. When.the cuttin. s.eed is.higher than.the determin.d value, the diamon. s.w can.become s.uck in.the travertin. block; this.s.tuation.can.be a problem for the block-cuttin. machin.. As.a res.lt, the optimum cuttin. s.eed obtain.d for the travertin. min.s.examin.d is.approximately 1.5-2.0 m/min.
