The monitoring of cutting force components is one the possibilities to control machining processes from point view its stability, machine tool spindle or loading. This paper presents and compares results experimental longitudinal sawing pine wood with 4 saw discs different teeth number (16 24) rake angle (10° 20°) during up (conventional) down (climb) revolutions (4000 min-1, 5000 6000 min-1) f...

To process ingots of Fe–Ga alloy single crystals into wafers, Fe–17% Ga were cut using multi-wire sawing or electric discharging and rolling. Further, their properties magnetization magnetostriction analyzed electron backscatter diffraction (EBSD) X-ray (XRD). It was observed that the curves changed with increasing rolling reduction. Although negligibly affected by deformation, shape curve as-g...

Arctic driftwood has reached the coast of Iceland for centuries. This material was used by inhabitants island as a building houses, boats, churches and pasture fences. Nowadays, is in furniture industry, finishing internal external walls buildings also artists. The properties differ to that original resource due long-term effects exposure Sea water ice. process can be considered natural modific...

In a five year prospective study of the vasoconstrictor response to cold 37 forestry workers were investigated in 1978 and again in 1983. The subjects were classified into three groups: group A (n = 13): no subjective finger symptoms in 1978 and continued sawing until 1983; group B (n = 12): no symptoms in 1978 and stopped sawing before 1983; group C (n = 12): vibration induced white finger (VW...

Traditional separation methods for thick-walled metal tubes include turning and sawing, which suffer from wasted raw material low efficiency. In view of this, this paper proposes a new process using impact load to promote crack generation tube separation. Based on the principles radial repeated load, stress concentration effect fatigue fracture, rapid initiation stable expansion are promoted. a...
