Enhancing energy efficiency is the key to realizing green manufacturing. One major area of interest in this regard improvement machine tools during production building materials. This project focuses on spiral milling wood plastic composites. To end, a response surface method was adopted develop model and establish relationship between conditions. Analysis variance based individual factors as well two-factor interactions performed gauge their effects efficiency. It found that depth...
This research focuses on the cutting performance of Al2O3 and Si3N4 ceramic tools in up-milling plywood, results which are as follows. First, whether tool material is or ceramic, forces at low-speed were less than those high-speed cutting, machining quality was greater that cutting. Then, low- higher tools, plywood milled by poorer tools. Finally, more suitable to machine wooden productions with much glue content for better machined quality.
Nuclear magnetic resonance (NMR) relaxation time distributions can provide detailed information about the moisture in wood. In this paper, bound water content and pore size swollen cell wall of two kinds softwoods (Pinus sylvestris Cunninghamia lanceolata) three hardwoods (Populus sp., Fraxinus excelsior L., Ochroma lagopus) were determined by NMR cryoporometry. The total almost exceeds 35%, based on dry mass, which is obviously higher than fiber saturation point (FSP) (appr. 30%) measured...
The effect of sharpness angle on tool wear and the machined surface roughness were investigated in wood flour/polyethylene composite (WFPEC) peripheral up-milling using cemented tungsten carbide (TC) tools. It was shown that nose width edge recession increased with increasing feeding length. During milling process, smallest for a 45°, followed by tools angles 55° 65°. highest angle, decreased after length 40 m. had positive roughness, width. little roughness. clearance face worn angle....
Three types of reinforcement materials, a carbon fiber-reinforced polymer (CFRP) sheet, glass (GFRP) mesh, and composite the CFRP sheet GFRP were used to reinforce poplar laminated veneer lumber (LVL), multi-step hotpressing method was also applied.The mechanical properties, i.e., modulus rupture (MOR), elasticity (MOE), horizontal shear strength (HSS), reinforced LVL investigated, as well effects lay-up location sheet/GFRP mesh composite.The results indicated that applying hot-pressing...
The effect of chip thickness, rake angle, and edge radius on cutting forces morphology in wood plastic composites (WPCs) orthogonal was investigated.Three types WPCs, Wood flour/polyethylene composite (WFPEC), flour/polypropylene (WFPPC), flour/polyvinyl chloride (WFPVCC), that were tested exhibited different behavior with respect to the machinability aspects.The WFPVCC highest, followed by WFPPC WFPEC.The most significant factor parallel force these three WPCs which explained more than 90%,...
Abstract In order to meet the requirements of cutting efficiency and economy in processing stone plastic composite, milling tests composite were conducted using straight tooth diamond tools. Cutting forces temperature measured under different parameters. Response surface methodology was used analyze variation determine significant contribution each variable its two‐level interaction. The correlation between actual predicted results found by building mathematical models temperatures, which...
In order to improve the decorative properties of Magnesium-Glass-Board (MGB), surface morphology and decoration performance MGB, are studied in detail by using profilometer, microscope SEM, influence its characterization, such as roughness, porosity wettability, on MGB is analyzed comparing with medium density fiberboard (MDF) particleboard (MDP). The results first showed that has a porous structure, but MDF MDP not, resulting poor MGB. Second, it found wettability better than others. Third,...
To investigate the impact of different milling parameters on forces, chip morphology, and machined surface quality during Paulownia process, we conducted experiments using cemented carbide single-tooth shank cutters. Additionally, established a response model (RSM) to analyze quality. The key findings are as follows: forces along parallel tangential axes decrease with an increased tool rake angle spindle’s rotational frequency, but they exhibit positive correlation depth. effect frequency...
The effects of process parameters (adhesive spread, press time, and applied pressure) on the response parameter (shear strength) pine wood bonded with PVAc were studied.Response surface methodology was for design experiments analysis results.A mathematical model developed to establish relationship between parameters.The results showed that major factors adhesive spread pressure.The shear strength increased as pressure within certain ranges.
