This paper analyses three components of total cutting force and chip shape changes when finish turning 17-4 PH (precipitation hardening) stainless steel. A Finite Element Method (FEM) simulation forces was also performed using the Johnson–Cook constitutive model. The results were compared with those obtained from experimental studies. Variable feeds 0.05–0.4 mm/rev depth cut 0.2–1.2 mm a speed 220 m/min used. studies carried out under dry wet cooling conditions use minimum quantity...
Titanium alloys are included in the group of diffi cult-to-cut materials.The use diff erent methods to reduce temperature machining zone is one factors infl uencing performance machining.The most commonly used method fl ood cooling.On basis recent research, conventionally cutting uids can cause some health problems for machine operators.Moreover, it was found that they environment during storage and disposal.Therefore, years, aspects biodegradable reduction number metalworking processes have...
This study combined simulation and experimental tests to analyse the cutting performance of three solid carbide end mills with distinct geometries during milling 7075 aluminium alloy.For tests, uncoated were employed, which differed in rake angle, clearance helical pitch.Simulation revealed temperature distributions resultant forces.The machining a cutter higher blade angle was shown cause an increase zone.However, sharper tool, decrease forces not observed.The simulated distribution on edge...
The use of the minimum quantity lubrication (MQL) method during machining leads to reduced consumption cooling and lubricating liquids, thus contributing sustainable machining. To improve properties liquids used under MQL conditions, they are enriched with various types micro- nanoparticles. purpose this study was investigate effect addition graphite micropowder (GMP) on tool life, cutting force components, selected surface roughness parameters finish turning Ti-6Al-4V titanium alloy...
Titanium alloys, particularly Ti-6Al-4V, are widely used in many industries due to their high strength, low density, and corrosion resistance. However, machining these materials is challenging strength at elevated temperatures, thermal conductivity, chemical reactivity. This study investigates Recurrence Plot (RP) Quantification Analysis (RQA) analyze tool wear during the finish turning of Ti-6Al-4V. The tests were conducted under Minimum Quantity Lubrication (MQL). Three inserts (two...
Abstract Titanium alloys, especially Ti-6Al-4V alloy, are widely used in industry due to their good mechanical properties, such as high specific strength and excellent corrosion resistance. However, titanium alloys also difficult-to-cut materials. Metalworking fluids employed the machining process improve machinability of alloys. In recent years much attention has been paid use minimum quantity lubrication (MQL) techniques this study, tool wear its influence on components cutting forces have...
