The widespread use of 3D printing may create new industries, including home-based manufacturing, and present opportunities for business owners. Today, 3D printing technology is successfully used to produce most goods used today, from basic...

The sintering temperature and holding time have a significant impact on the densification of a ceramic compact. In this study, alumina inserts were made with varying sintering temperatures and holding times. The procedure began with the compacting of alumina powders inside a mould with trapezium and round shapes. These inserts were then sintered be...

An Advanced Rear Visualization (ARV) based on camera technology is becoming more widely available in the automobile market as it increases the ability to see beyond the area of a mirror's image as well as helping to eliminate the driver’s blind spot. Besides, it assists the driver in parking, reversing, and maneuvering safely. Therefore, it is nece...

High Thermal Conductivity Steel-150 (HTC-150) is a specific steel designed for use in the hot stamping process as a stamping die. HTCS-150 die steel was difficult to machine due to its high strength, hardened state, and high thermal conductivity characteristics, which necessitated parameter control for a fine surface finish and maximum tool life. T...

span>This paper describes the design and development of a measuring tool using a mobile robot. At present, contractors are measuring distances using measuring tape which has few limitations. This includes using of another manpower or a marking flag. The Robot Measuring System is designed to measure distances at multiple conditions such as smooth an...

Road safety has become more concern due to the number of accidents that keeps increasing every year. The safety system includes from simple installation such as seat belt, air bag and rear camera to more complicated and intelligent system such as braking assist, lane change assist and blind spot monitoring. This paper proposed a Smart Vehicle Blind...

The research was executed to study the effect of Carbon Fiber Reinforced Polymer (CFRP) micro drilling parameter on hole accuracy. The main contribution of this research is to improve manufacturing process of hole micro size by finding the optimum parameter for excellent hole accuracy. However, to obtain the optimum parameter, the behavior of hole...

Carbon Fiber Reinforced Polymer (CFRP) is extensively used in aircraft and automotive industries due to it exceptional material properties such as high strength to weight ratio and corrosion resistance.

This paper describes the design and development of a shoe dryer using a microcontroller. Nowadays, people often travel and sometimes in rainy day, they need to dry their shoe in a very shorttime anywhere.However, very rare of places including shopping mallandhotel provide a shoe dryer. The shoe dryer is designed to help people who are in hurry to d...

A common voltage-controlled oscillator (VCO) architecture used in the phase locked loop (PLL) is the ring oscillator (RO). RO consist of number of inverters cascaded together as the input of the first stage connected to the output of the last stage. It is important to design the RO to be work at desired frequency depend on application with low powe...

Drilling is a continuous machining process. Drilling is a cutting process that uses a drill bit to cut a hole of circular cross-section in solid materials. This forces the cutting edge against the work piece, cutting off chips (swarf) from the hole as it is drilled. Various cutting tools are available for drilling, but the most common is the twist...

Chuck is a device used to clamp any material that operates with the turning of the machine and it is connected to the headstock spindle of the lathe. However, the limitation is that the thickness of the workpiece must not be less than the area of clamping on the chuck. In this a new magnetic clamping for attaching and detaching the workpiece on the...

Drilling operation is an operation which produces holes by bringing a rotating cutter into contact with the workpiece. Drilling operation is commonly done in drill press, however some of the time; it is done on mills or lathes. Holding parts to be drilled is one of major problems faced by the students. If the material has many holes to be drilled,...

Milling machine vise is one of the common clamping device used in the industry and for learning purposes. The purpose of milling vise is to reduce working time by permitting snappy setup. It also functions as a supporter during the machining process and help to increase accuracy of the completed parts. However, limited surface of the work-piece can...

The corrugated fiberboard structure is widely used in manufacturing industries as a light-weight high-stiffness structure board and other applications. However, the strength characteristic of a single face fiberboard based on glass fiber reinforced plastic is not well understood. The objective of this study is to propose and estimate the strength o...

Clamping or work holding is a generic term for any device used to hold the workpiece during machining process. However, only limited surface of the workpiece can be cut in a single clamping. The objective of this project, is to design, develop and evaluate fixable rotation clamping method for milling process. After the device was developed, one tes...

In recent times, numerical simulation techniques have been commonly used to estimate and predict machining parameters such as cutting forces, stresses, and temperature distribution. However, it is very difficult to estimate the flow stress of a workpiece and the friction characteristics at a tool/chip interface, particularly during a high-speed cut...
