This piece of work deals with the influence assessment kind coating cutting inserts and their wear on dimensional accuracy top layer microstructure roughness surface machined constant parameters vc = 85 m/min, f 0.14 mm/obr ap 0.2 mm. The tests were performed shafts made Inconel 718 material under conditions finish turning, requiring a tool life more than 20 min. identical geometry fine-grained carbide covered coatings applied by PVD CVD method. values obtained diameter dimensions assessed...
This paper presents a comparison of surface morphology obtained after machining Inconel 718 by the conventional insert, Wiper insert and using cutting made Spark Plasma Sintering (SPS). The shape special was employing Wire Electrical Discharge Machining (WEDM). focuses on description topography turning in dry wet conditions. performed investigation included longitudinal tests range variable feeds. Surface measurements have been with application Nanoscan 855. analysis includes parametric...
Cutting inserts made of ceramic materials are used in rough machining processes Inconel 718. This article compares sintered carbide S205 with 6160 after finish turning 718 a hardness 45 HRC. The evaluation focused on insert wear, surface topography and changes cutting edge radius. results show differences the wear inserts. characterize formation buildup rake face, while tend to form flank face. Furthermore, more prone notch wear. Surface analysis revealed individual high peaks surfaces...
The technology of producing threads, especially in materials that are difficult to cut, is a rare subject research and scientific publications. requirements for the production these elements apply not only geometry, but also quality surface obtained. This particularly important aviation industry, where durability threaded connection affects passenger safety. Due design thread, its assessed visually industrial practice. authors this study decided examine topography external threads made by...
This paper presents the results of investigation that was performed on shafts composed Inconel 718. Tests were in dry and wet conditions. Cutting parameters, such as feed depth cut, constant. The cutting speed changed. for various shaft shapes: cylindrical, taper 30°, 45°, sphere. For reason, value angle between machined surface edge lowest values roughness Ra Rz, obtained a larger edge. showed speed, machining conditions (dry machining), variable influenced roughness. Application higher...
Nowadays, great emphasis is placed on increasing the effi ciency of machining processes.However, this cannot be done at expense quality worsening machined surface.In paper infl uence Wiper geometry Ra and Rz surface roughness parameters described when fi nishing turning materials used in aviation industry: austenitic stainless steel XCrNiNb18-9, low alloy 14NiCr14 aluminum A356, as well chips generated cutting process terms shape were assessed.It was found that for lowest tested feed rate...
The work deals with the influence of reach applied tool holder on edge wear, dimensional accuracy and surface quality defined by topography as well roughness machined surface. research has been conducted specimens made Inconel 718 in configuration sleeves, within scope finish turning constant cutting parameters, vc = 85 m/min; f 0.14 mm/rev; ap 0.2 mm. material under machining undergone heat treatment procedures such solution precipitation hardening, resulting a hardness 45 ± 2 HRC.
