“…e results of the experiments for the flat surface grinding process vibration conditions and force measurement have demonstrated that the higher values of grinding forces were obtained in the normal component (see Table 2) which concurs with the previous research findings in the literature [27,35]. It can be noted that, in the range of the cutting speed from 20 to 25 m/s and the depth of cut from 0.005 to 0.01 mm, the increase of the cutting speed and the depth of cut parameters is connected with an increase in the grinding forces and the amplitudes of vibration in both tangential and normal directions, but the grinding forces and vibrations grow more quickly in normal direction than in the tangential direction.…”

This article presents a new model of the flat surface grinding process vibration conditions. The study establishes a particular analysis and comparison between the influence of the normal and tangential components of grinding forces on the vibration conditions of the process. The bifurcation diagrams are used to examine the process vibration conditions for the depth of cut and the cutting speed as the bifurcation parameters. The workpiece is considered to be rigid and the grinding wheel is modeled as a nonlinear two-degrees-of-freedom mass-spring-damper oscillator. To verify the model, experiments are carried out to analyze in the frequency domain the normal and tangential dynamic grinding forces. The results of the process model simulation show that the vibration condition is more affected by the normal component than the tangential component of the grinding forces. The results of the tested experimental conditions indicate that the cutting speed of 30 m/s can permit grinding at the depth of cut up to 0.02 mm without sacrificing the process of vibration behavior.

“…The experiment (DoE) was planned in Design-Expert 13 software. One of the methods used in designing of experiments is the surface response method (RSM) -multicomponent research designs are based on it [28]. For the researches central composite face centered design (CCF) was applied for two dependent variables assuming levels of values ( 32 ) where α = 1.…”

A method of the measurement of temperature and grinding force components during fl ute grinding of solid carbide end mills was presented. The tests were performed using two diamond grinding wheels: with a resin bond (S1) and with a metal bond (S2). A diamond grinding wheel of 1A1 type and a rectangular cross-section was used. An ultrafi ne grained carbide with a grain size of 0.2 to 0.5 μm, characterized by high hardness (1730 HV30) and very high tensile strength (4600 MPa) was used. The fl utes were grinded in one pass, thus replacing rouging and fi nishing. The temperature of grinding was recorded using thermocouple type K, NiCr-Ni. The measurement of forces was conducted using a rotary piezoelectric dynamometer. Surface topography was recorded with the Alicona Infi -niteFocus G4 microscope. The experiment was planned in Design-Expert 13 software. Mathematical models were developed, describing the relationships between the grinding speed and the feed rate as a function of the grinding temperature, grinding force and roughness parameters of the fl ute. For both grinding wheels, the Fn grinding force was recorded in the range of 28-110 N, the temperature in the range of 32-200 °C and surface roughness Sa in the range of 0.31-0.76 μm. The best grinding result, in terms of low grinding forces and temperatures was achieved for the grinding wheel with the metal bond (S2). For the resin grinding wheel (S1), for the selected technological parameters, grinding burn occurred.

The article presents the results of research on the impact of feeding marine reciprocating internal combustion engines with blends of diesel fuel and n-butanol on their performance parameters. The study includes a research plan and empirical results, in which the engine efficiency and emissions of harmful compounds in the exhaust gases were determined. The research indicates that it is resonable to use fuel blends containing n-butanol. N-butanol positively affect the concentration of NOx has positive impact on reducing the toxicity of exhaust gases. An important aspect of the passive defence of a vessel is the reduction of exhaust gas temperature under nominal loads.
