Fertilizer application control in reason is the key technology to improve operation quality, reduce fertilizer pollution, and cut down costs of production. A control system of variable rate fertilizer is developed based on microcontroller chip in the paper. The system can automatically control flow dosage by adjusting feed gate opening size and changing hydraulic motor speed of fertilizer conve...

A low power pulse triggered flip-flop with signal feed through scheme using Conditional Pulse Enhancement technique is presented in this paper. The proposed design adopts a modified True Single Phase Clock Latch structure and employs a signal feed through scheme to enhance the delay. The long discharging path problem in conventional explicit type pulse triggered flip flops are successfully solv...

One of the factors which are usually difficult to be measured in mills is the grindability and distribution of feed under real situation and in a short time. In the condition of achieving a fast and convenient way to determine these parameters, the proper relationship between energy, hardness and particle size distribution can be obtained. Feed hardness is one of the most important factors in g...

The selection of proper machining-parameters viz. feed, speed and depth of cut is an important task for obtaining the desired performance in the turning process. This work proposes a neuro-fuzzy control scheme for the selection of feed and speed in a single pass turning. The scheme provides the manufacturer a flexibility of specifying the objectives in linguistic terms. The scheme is dependent ...

One type of legume that is very suitable to be used as a raw material for making lobster feed the sworded koro nut (Canavalia ensiformis). Soybeans which are source vegetable protein can now supported by sword beans. The purpose this study was examine quality artificial using Koro Sword Nuts ensiformis) substitute soybean flour Sand Lobster (Panulirus homarus) feed. method experimental with RAL...

Within the context of High Speed Machining, it is essential to manage the trajectory generation to achieve both high surface quality and high productivity. As feed drives are one part of the set Machine tool Numerical Controller, it is necessary to improve their performances to optimize feed drive dynamics during trajectory follow up. Hence, this paper deals with the modelling of the feed drive...

A new method for workpiece error analysis and compensation in turning is introduced. It is known that the workpiece error consists of two parts: machine tool error (including the geometric error and thermal-induced error) and cuttinginduced error. The geometric error of the machine tool is independent on machining operation and, hence, can be measured o€ -line using a ®ne-touch sensor with a Q-...

In this study, the optimization of process parameters for milling of glass fiber reinforced polymer (GFRP) composites using grey relational analysis has been investigated. Experiments are conducted using helix angle, spindle speed, feed rate, depth of cut and fiber orientation angle as typical process parameters. The grey relational analysis (GRA) is adopted to obtain grey relational grade for ...

Micro drilled holes are utilized in many of today's fabrication processes.Precision production processes in industries are trending toward the use of smaller holeswith higher aspect ratios, and higher speed operation for micro deep hole drilling. However,undesirable characteristics related to micro drilling such as small signal-to-noise ratios,wandering drill motion, high aspect ratio, and exce...
