“…This means that there are no deviations both horizontally and vertically on the measurement results for a certain distance. Straightness of the component surface is very important in machining such as lathes, scrap machines, milling machines, and grinding machines due to the work system requires a very precise level of straightness [28]. The skills to make the surface of the workpiece completely straight are also necessary, including how to check the straightness itself [24].…”

The manufacturing technology has developed rapidly, especially those intended to improve the precision. Consequently, increasing precision requires greater technical capabilities in the field of measurement. A prototype of a 3-axis CNC milling machine has been designed and developed in the Research Centre for Electrical Power and Mechatronics, Indonesian Institute of Sciences (RCEPM-LIPI). The CNC milling machine is driven by a 0.4 kW servo motor with a spindle rotation of 12,000 rpm. This study aims to measure the precision of the CNC milling machine by carrying out the measurement process. It is expected that the CNC milling machine will be able toperform in an optimum precision during the manufacturing process. Accuracy level testing is done by measuring the deviations on the three axes namely X-axis, Y-axis, and Z-axis, as well as the flatness using a dial indicator and parallel plates. The measurement results show the deviation on the X-axis by 0.033 mm, the Y-axis by 0.102 mm, the Z-axis by 0.063 mm, and the flatness of the table by 0.096 mm, respectively. It is confirmed that the deviation value is within the tolerance standard limits set by ISO 2768 standard. However, the calibration is required for this CNC milling machine to achieve more accurate precision. Furthermore, the design improvement of CNC milling machine and the application of information technology in accordance with Industry 4.0 concept will enhance the precision and realibility.

“…Bal (2018) studied the influence of some machining parameters on the surface roughness and processing time of CNC machine. Recently, Bal and Gündeş (2020), investigated the effects of the moisture content and density of MDF formed using CNC machine on the surface roughness. In addition, Bal and Dumanoğlu (2019) studied the effects of the spindle speed and feed rate on the processing time and energy consumption of a CNC machine, and the surface roughness of a cabinet door using vectorial forming method.…”

Aim of study: The aim of this study was to determine the effects of cutter parameters on the energy consumption of CNC machine, and surface roughness of medium density fiberboard (MDF). Material and methods: Experiments were conducted using a three-axis CNC router. The energy consumption and surface roughness values were measured using a wattmeter (TT-Technic PM 001) and roughness tester (Mitutoyo SJ 210), respectively. The values of the Ra, Rq, and Rz roughness parameters, and energy consumption were determined. Main results: The surface roughness increased with increases in the step over and feed rate, whereas the energy consumption decreased. In addition, the energy consumption increased when a high spindle speed was used. When the spindle speed is increased from 8000 rpm to 16000 rpm, the energy consumption increases by 154%. When the stepover is increased from 20% to 60%, energy consumption is reduced by 63%. When the feed rate is increased from 3 m/min to 7 m/min, the energy consumption is reduced by 60%. Highlights: The energy consumption increased as the step over and feed rate decreased. The energy consumption increased as the spindle speed increased. The surface roughness increased with the step over and feed rate

“…Many different factors such as surface treatment direction, density, wood type, chemical and anatomical structure of wood, moisture content, cutter type, cutting feed rate and depths, the heat treatment temperature etc. play a role in the surface roughness values of the wood material (Baysal et al 2014;Pelit et al 2015;Ayata et al 2018;Bal and Gündeş, 2020;Aras and Sofuoglu, 2021;Rohumaa et al 2021;Sofuoglu, 2021). Regarding the heat treatment temperature, the highest surface roughness value (7.305 μm) was obtained in the control samples, whereas the lowest (6.210 μm) was determined in the samples that heat treated at 200°C.…”

The purpose of this paper is to determine the effects of heat treatment on some properties of black pine (Pinus nigra A.) and larex (Larix decidua), woods. For this purpose, test samples were heat treated at 140, 160, 180 and 200°C for 2 and 5 hours. The air-dried density, equilibrium moisture content (EMC), surface roughness and bonding strengths of the test samples were analyzed. The average surface roughness parameter (Ra) was analyzed parallel to the grains. The results indicated significant differences depending on the wood species, heat treatment temperatures and treatment times. Based on the findings in this study, all parameters decreased depending on the heat treatment conditions. The density and EMC values of the control specimens were higher than the heat-treated samples. Also the surface roughness values obtained in black pine samples were higher than larex samples. On the other hand, bonding strength values obtained in larex samples were significantly higher than that of black pine samples. These parameters should be taken into account in the application areas of heat-treated wood material, the usage amount of which is constantly evolving in the woodworking industry.
