Accurate prediction of machining cycle times is important in the manufacturing industry. Usually, Computer-Aided Manufacturing (CAM) software estimates using commanded feedrate from toolpath file basic kinematic settings. Typically, methods do not account for geometry or tolerance and therefore underestimate considerably. Removing need machine-specific knowledge, this paper presents a data-driv...

For example, the feedrate and accuracy of a weighbatching system’s conveyor or feeder doesn’t exclusively determine the system’s overall capacity and accuracy. Other factors that may affect productivity and success include material delivery method, infeed rate, surge vessel capacity, weighing equipment location in relation to mixers, hopper and chute design based on the material’s physical prop...

This paper presents a new 6 degree-of-freedom cable-driven parallel robot fully constrained by 8 cables. should perform medium size 3D part printing. Its distinguishing feature is radial cable winding that relevant due to the small diameter (0.54 mm) and maximum length (1.732 m, 1 m cube diagonal). solution has advantage of being compact easy design. The trajectory planning uses full geometric ...

Feedrate has a great influence on contour error in five-axis machining. Accordingly, it is of significance to plan the time-optimal feedrate curve considering constraint achieve high-accuracy and high-efficiency Aiming at improving control accuracy model linearization loss optimizing machining time, PSO-based optimization algorithm for with proposed this paper. Firstly, relationship between par...

land cover map is important for many urban planning and management activities. in this study, in order to produce land cover map of arak city, digital image of liss-iii scanner acquired on 16 june 2006 were employed. first of all, geometric correction with rmse 0.58 pixel was applied. considering the mountainous condition of the study area, topographic correction was applied to the image. in su...

Friction stir welding (FSW) adalah suatu teknologi pengelasan yang merupakan proses solid-state joining bisa digunakan untuk menyambungkan material aluminium dengan mampu las rendah. Proses FSW memanfaatkan putaran dari tool menggesek dua buah lempengan logam akan disambung. Aluminium 2024 T3 ketebalan 4 mm disambung menggunakan variasi feedrate 13 mm/menit, 15 dan 25 kecepatan spindle 910 rpm ...

In this note we construct measures of maximal entropy for a certain class of maps with critical points. The main application of our result is the existence of measures of maximal entropy for the so-called Viana maps.

Sculptured surface machining (SSM) is one of the continually used manufacturing processes for die/mold, aerospace(especially turbine blades), precision machine design, bio-medical devices and automotive industries. Developments of machining technologies for quality enhancement of machining results has become a very important fact in current real industry. Off-line feedrate adjusting is a new me...
