STEP means Standard for the Exchange of Product model data. It consists of the 3D geometry of a computer-aided design (CAD) model in the configuration of boundary representation (B-rep). By extracting, refining and decoding the geometric data correctly, the data can be utilized for writing G-code for Computer Numerical Control (CNC) machining application. Usually G-codes can either be manually generated by skilled machinists or automatically generated by computer-aided manufacturing (CAM) software. However, manually generated G-code is inefficient and susceptible to error. Meanwhile automated generation G-code requires significant setup cost. This paper describes the design and development of an integrated interface system, an instrument aimed to be used to analyze STEP files and generate machining tool path based on ISO 6983 format. This developed interface reduces the need for high setup cost as w...

With the aim to avoid improper use of nitrogen fertilization on plants and to assist local farmers in improving plants monitoring, this paper presents an economical and non-destructive method in determining nitrogen status of Napier grass using digital image processing approach. Three authentic techniques of image segmentation Otsu, K-means clustering, and watershed transformation were applied and compared to recognize the most accurate method for segmenting leaf pixel from its background. Otsu was discovered as the most efficient technique with less time-processing. Out of 36 features extracted from the segmented image, kurtosis, skewness and standard deviation of the blue color image were the most related features in classifying nitrogen status of the images. Classifiers like KNN, decision tree, and linear discriminant were used to classify the leaves image and nitrogen status accordingly. The accuracy of 100% was recorded in classifying the leaves image using decision tree and KNN classifier.

Ini kerana, rumah Melayu tradisional adalah suatu warisan senibina tempatan sebagai rumah kediaman yang mempunyai pelbagai unsur keunikan tersendiri dan istimewa, di mana bermula peringkat perancangan pembinaan, pemilihan tapak, orientasi, takwin pembinaan, penggunaan bahan dan sebagainya sehingga rumah itu siap didiami. Keunikan ini melibatkan pertalian dengan penggunaan unsur-unsur kepercayaan agama, adat-resam, pantang-Iarang, semangat di mana ianya menjadi pegangan dan pengaruh yang mendalam terhadap penghuni yang mendiami rumah melayu tradisional ini disamping kehalusan nilai seni ketukangan

These data can be fully utilized and integrated into a larger manufacturing organization, such as a computer-aided manufacturing (CAM) environment for computer numerical control (CNC) machining applications based on ISO 6983. The 3D models of 2D machining profiles were created in CAD software and saved as STEP files. The data structure was analyzed by comparing the geometric entities of the CAD model and the STEP file. The algorithm was created using the hypertext preprocessor (PHP) programming language and produced a computer interface system to convert STEP files into G-code format. The machining blocks with profile machining features were simulated using a CNC simulator and PC-based open architecture control (OAC) software. The G-code was validated on a three-axis CNC mi...

Each student is assigned to create a specific jig design in their assignment task. The scope of the assignments covers a range of processes starting from the generation of ideas, sketches, technical drawings and eds with the prototype development. However, in previous batches of students, they were struggling with the issue of limited equipment and prototype development skills which consequently affects the quality of prototype being produced. To overcome this problem, a modular has been developed using CAD software to help students applying the components that are ready to be used as a jig to hold the workpiece. Through this idea generation method, students just need to select the existing components to develop the jig. They can also use the modular to assist them in their presentation. The results obtained from the use of modular show that student...

The population is the academic staff in Malaysian polytechnic which was clustered into five regions (Northern, Central, Western, Eastern and Borneo) which involved 363 samples. The instruments used to collect data were adopted from established previous studies. The data were analyzed using descriptive statistics and regression analysis. The results show that there only distributive justice and interactional justice has a significant relationship of OCB. Finally, the findings have supported the social exchange theory.
