Development of Spark Electrode for an Explosion Vessel
This project is about developing of spark electrode for ignition system by
basically using an electrical discharge. A proper set up or assemble for the ignition
system need to be done to produce desired spark energy. However, current spark
ignition system is not customizing to the research explosion vessel. Further, different
spark and explosion propagation are also needed to suite the ignition for the gaseous
flammability. Therefore, a suitable ignition system is being created to ensure that energy
produced in the spark can be used to study the ignition system for that gaseous
flammability. A long electrode holder needs to be design and fabricate to suite the
explosion vessel. The orientation for the explosion vessel needs to be understood with
the suitable spark gap. According to the working principle of ignition coils, the function
is determined and the usage is put as a step up transformer to increase the output
voltage. The calculation of the ignition energy is based on discharge capacitor principal.
The experiment provides an effective method to produce an ignition spark for a research
explosion vessel. Further, the factor that affects the spark size will be determined and
the fuctor will be for the experiment to see the variation of the spark development. The
ignition energy can be varied by adjusting the current comes from a power supply. The
spark energy should be measureable and highly important in this project is how the
safety is conduct to protect against physical or other types or consequences of failure,
damage, error, accidents, harm or any other event which could be considered nondesirable.
From the finding, the voltage inputs were taken as manipulation factor and the
size of the spark were different based on different voltage input. Furthermore, the factor
that gives much affect towards the spark size and ignition energy was the capacitance
value. Higher capacitance value gives higher ignition energy and further increase the
sparks sizes that were produced. Ignition energy and peak pressures vary strongly as a
function of initial temperature, but are a weak function of mass loading
Development of an Open Soft CNC System Based on STEP-NC and Function Blocks
Modern manufacturing industries have put on increasing demands on computer numerical controllers (CNC) for it to be able to work with and process higher level input data described using languages such as STEP-NC, rather than the outdated G-codes. The research work described in this paper is about the development of a soft CNC controller that can process STEP-NC (ISO 14649) data. Function blocks (IEC 61499) are also used as the interface between the STEP-NC data model and the controller. The layered STEP-NC/FB architecture is proposed, which simplifies the design of the controller with layers responsible for data processing, data storage and execution. With the object-oriented, Model-View-Control design pattern, the STEP-NC/FB architecture supports the design framework, in which simulation of the machining becomes a natural and inherent part of the design process, with seamless transition from simulation to actual machining
