An experimental study of the abrasive water jet cutting process Inconel 718 alloy samples with varying values speed, flow rate and material height was carried out. Surface roughness waviness were measured at different depths, variation kerf angle studied. It shown that depth cut has greatest effect on waviness. The sample no impact a particular cut. As increases, in most cases, increase as well. been proven speed negligible surface roughness, but it significant waviness, other hand, depends...
High feed Milling is a new milling method, which allows to apply high rates and increase machining efficiency. The method utilizes face cutters with very small entering angle, of about 10°–20°. Thus, the cut layer cross-section different than in traditional milling. In order examine (HFM), experimental tests were conducted, preceded by an analysis cutting zones when HF cutter. 42CrMo4 steel use cutter characterized dependent on axial depth ap insert radius r values, as well conventional...
One type of milling process is the face flat surfaces using a toroidal cutter. A key feature this that changes in depth cut alter entering angle, impacting dynamics by shifting cutting force proportions. To investigate phenomenon, an experimental study was conducted on different sets parameters. Cutting components were recorded, as these signals provide essential information about process. Statistical indicators then calculated and analyzed based recorded data. Following this, recursive...
<title>Abstract</title> Abrasive water jet (AWJ) cutting is an unconventional machining technique widely used to process various materials, including metals, plastics, ceramics, and stone. The key advantage of the AWJ its low temperature, which prevents thermal defects in material’s surface layer. However, abrasive dissipates within material, leading formation irregular geometry. This study presents experimental investigation X39Cr13 stainless steel determine relationships between...
