“… Power (Watt) needed for cutting a single frond: Measured using a digital power meter (Tunex)/(Walt). The cutting power was calculated by subtracting the power consumed while the tool is running free (without cutting) from the measured power while cutting the frond [21], as illustrated in equation ( 1)…”

Traditional tree management is laborious and costly, thus this work aimed to study the performance of two different types of frond cutting saws (reciprocating saw and vibrating saw) and examine the two saws on five date palm varieties. Four parameters were examined, including cutting time for a single frond, the power needed for cutting a single frond, frond cutting productivity expressed as tree/h, and vibration conveyed to the worker’s hand. A field experiment was designed according to the nested randomized complete block design, including five date palm varieties as the main plot and the type of saw as a sub-plot. Means were compared using the least significant differences (LSD 0.05). Results indicated that Bream variety required the least time for frond cutting. The reciprocating saw exhibited efficiency in saving the time required for frond cutting, while the vibrating saw took significantly longer time needed for cutting a single frond. The highest number of fronds cut in one hour was recorded in Bream variety, again significantly higher than the number of other studied varieties. Moreover, the reciprocating saw achieved significantly higher productivity than the vibrating one, indicating that the productivity of the reciprocating saw is almost three times more than the vibrating saw. Maximum productivity was recorded in Bream variety, while the least was recorded in Tebarzal using the vibrating saw. Moreover, results indicate that the variety and the type of saw have a vital role in productivity since as the thickness of a frond increases, the cutting takes more time and ultimately reduces the number of date palms to be pruned per hour. Results also exhibited that vibrating saw reduced the consumed energy during frond cutting. Additionally, results revealed that the minimum power consumed by a vibrating saw was in Bream variety, while Tebarzal consumed the upmost energy when a reciprocating saw was used. Maximum vibration on X-axis was reported in Bream variety when a vibrating saw was used. Additionally, the reciprocating saw exhibited the highest vibration compared with the vibrating saw. Moreover, the reciprocating saw caused the lowest vibration in Tebarzal variety. Results indicated that the vibration imposed by both saws reached the maximum value in Bream variety. The vibrating saw resulted in the higher vibration toward Z axis, while the Reciprocating saw resulted in higher vibration toward X axis, which was more than eight times that recorded by the vibrating saw. Results indicate that vibration toward the Y axis increased significantly in Bream variety compared with others. Again, as in the situation with X and Z axis, the reciprocating saw exhibited the highest vibration compared to that resulted from using a vibrating saw which was more than three times the vibration caused by the vibrating saw.

“…Studies on the properties of thin and ultra-thin furniture panels can be found in the specialised literature. Mainly, these are studies of plywood [4][5][6][7][8], PB [5,9], MDF [3,5,[8][9][10][11][12][13], oriented strand board (OSB) [9] or a combination of some of them [3]. Some authors are looking at possibly reinforcing wood-based panels to increase strength and deformation properties, such as with thin aluminium sheets [14].…”

One of the biggest challenges for designers and manufacturers of furniture is to reduce the thickness of conventional furniture materials such as particleboard (PB), medium-density fibreboard (MDF) and plywood. Designing furniture based on thin (less than 16 mm) and ultra-thin materials (less than 10 mm) is desirable for aesthetic reasons and because of the substantial material savings. However, the use of thin and ultra-thin materials reduces the strength of the furniture, especially the strength and deformation resistance of the joints. This study aimed to establish the possibilities for efficient furniture construction made of thin and ultra-thin materials using mitre joints. For this purpose, 14 types of L-type joints were tested: 12 glued and 2 detachable. The joints were made of eight wood-based panels and one non-wood panel. The bending moments and the stiffness coefficient under compression were determined. The obtained results show that the mitre joints made of laminated material with high-pressure laminate (HPL), 8 mm thick, MDF achieved the highest bending moment, and the highest stiffness coefficient was achieved by joints made of 10 mm thick compact HPL. Compact HPL joints were significantly affected by the type of adhesive used. Detachable joints had a relatively high bending strength but very low stiffness.

“…In general, the e ciency of saw blades is in uenced by the workpiece characteristics, machining parameters, blade body, sawtooth, and active machine power [7,8]. A considerable amount of studies have been made in the eld of circular saw blades, which can be divided into the following categories: (1) analysis of energy consumption and cutting forces [9,10], (2) monitoring of sawtooth wear or workpiece surface integrity [11,12], (3) analysis of noise reduction [13,14], and (4) dynamic analysis [3,12,15]. A careful study of the aforementioned literature shows that these studies are mainly focused on conventional saw blades.…”

Cemented carbide circular saw blades are widely used in the metal and nonmetal manufacturing industry for cut-off and cut-tail production. High energy consumption and intense noise emission from conventional-type blades are urgent environmental issues to be solved. Hence, a laminated-resin blade is proposed to study the effect of adding a damping structure to the blade body on its cutting performance.Apart from reduced energy consumption, lower noise and high-quality surfaces are required by manufacturers. In this work, a laminated-resin blade and a conventional blade were compared regarding the details of cutting force and energy consumption, noise emission, and surface integrity. In addition, the effect of cutting uid on conventional saw blades was analyzed in terms of cutting force and noise emission. Experimental results show that the cutting force and noise of the laminated-resin blade were less than that of the conventional one, indicating reductions of 27.8% and 18 dB, respectively. Especially a reduction of more than 20 dB sound level was achieved in the high-frequency band. Lower cutting force attained by the laminated-resin blade showed that smoother cuts could be achieved. Cutting with cutting uid is superior to dry cutting in terms of cutting force, noise level, and workpiece surface integrity. The research sheds new light on the design of damping structures on saw blade bodies and quantitative analysis of the cutting performance.
