Influence of PLA Filament Conditions on Characteristics of FDM Parts
(MDPI, 2018-08)
Additive manufacturing technologies play an important role in Industry 4.0. One of the most prevalent processes is fused deposition modelling (FDM) due to its versatility and low cost. However, there is still a lack of ...
Mechatronic modeling of a parallel kinematics multi-axial simulation table based on decoupling the actuators and manipulator dynamics
(Elsevier, 2016-11-07)
In this work a mechatronic model was developed for a parallel Multi-Axial Simulation Table (MAST) mechanism. The dynamics of the mechanism was obtained using the principle of energy equivalence and Boltzmann–Hamel equations. ...
Mechatronics of a ball screw drive using a N degrees of freedom dynamic model
(Springer, 2017-10)
High performance position control in machine tools can only be achieved modelling the dynamic behavior of the mechatronic system composed by the motor, transmission and control during the design stage. In this work, a ...
Mean Stress Effect on the Axial Fatigue Strength of DIN 34CrNiMo6 Quenched and Tempered Steel
(MDPI, 2018-04)
The present study consists of a theoretical and experimental investigation of the effect of axial mean stresses on the high cycle fatigue behaviour of DIN 34CrNiMo6 high strength steel in quenched and tempered conditions. ...
Experimental Validation of the Kinematic Design of 3PRS Compliant Parallel Mechanisms
(Elsevier, 2016-11)
In this paper, a procedure for the kinematic design of a 3-PRS compliant parallel manipulator of 3 degrees of freedom is proposed. First, under the assumption of small displacements, the solid body kinematics of the 3-PRS ...
Analysis of the Process Parameter Influence in Laser Cladding of 316L Stainless Steel
(MDPI, 2018-09)
Laser Cladding is one of the leading processes within Additive Manufacturing technologies, which has concentrated a considerable amount of effort on its development. In regard to the latter, the current study aims to ...
Retained Austenite Control for the Soft Machining of High-Hardness Tool Steels
(MDPI, 2018-07-23)
Most high-hardness tool steels comprising forming dies require expensive finish machining operations to compensate for the dimensional distortion and surface oxidation caused by the die heat treatment. Precipitation-hardening ...
Wear And Friction Evaluation Of Different Tool Steels For Hot Stamping
(Hindawi, 2018-03-26)
The aim of this work is to investigate the durability of tool steels for hot stamping by comparing the wear resistance of three hot work tool steels. Friction and wear behaviours of different tool steels sliding against a ...
A Proposal for a Formula of Absolute Pole velocities between Relative Poles
(Elsevier, 2017-04-10)
In this paper is proposed a vectorial equation that relates the absolute pole velocities of three moving rigid
bodies with a planar motion of general type. From this equation, it is possible to obtain a relation between ...
Control Distribution of Partially Decoupled Multi-level Manipulators with 5 DOFs
(Cambridge University Press, 2017-02-01)
Multi-level manipulators are those mechanisms in which two or more levels,
that de ne the main chain of the manipulator, are joined in parallel to
each other. Besides, each level is linked to the base in parallel by ...
