Open Computer Numerical Control system (Open CNC) based on PC and the Windows operating system has been a major developing direction and a research focus of the current numerical control technology. At present, there have been all kinds of the Open CNC systems with high-speed and precision servo control boards, but they are too expensive. Therefore, developing an economical and practical motion controller is great significant for middle and small numerical control system

SUMMARYUp to now, most people are still cooking in the kitchen, which makes them feel fatigued and also makes the air polluted. With the development of the numerical control technology, it becomes more and more urgent to apply the related technology to the automatic cooking field. In this paper, the cooking technique for the Chinese dishes is introduced and China's first cooking robot, named AI Cooking Robot (AIC), is presented. The robot mainly consists of four parts: the wok mechanism, the stirring-fry and dispersing mechanism, the feeding mechanism, and the mechanism of leaving the material in the middle process. In order to adjust the temperature, the fire control system is also given in this paper. Experiments show that the new robot will be a milestone in the cooking automation science because of its cooking technique.

Tyre tread pattern mainly accounts for tyre performance and its endurance. In tyre mold processing, pattern block processing is technologically disturbing, of which the tread pattern is the most challenging. This article first analyses the function conversion of the points from point to plane to space along the tyre tread curve. Aided by GRIP language, it continues to make tread section with spatial curve, and then with the help of UG scanning order, it produces a three-dimensional diorama of accurate tyre pattern. To solve the problem of large errors arising in tyre mold processing with 3 axis numerical control technology, the article proposes a new method to produce tyre tread pattern with 3 axis technology and validates the method. The research contributes to dividing processing of tyre tread pattern, and reducing errors theoretically. Experiments had been done to illustrate that the method can achieve high quality and efficient processing.

The application of digital technologies (DT) has been on the increase within the manufacturing industries since a decade ago. It has been widely suggested that the onset of the COVID-19 pandemic has accelerated the adoption of DT in manufacturing industries worldwide, as countries have tried to contain and mitigate the spread of infection through lockdowns and stringent standard operating procedures (SOPs). Hence, a study was undertaken to evaluate this trend in the Malaysian wood products industry, and to identify the key DT used. A questionnaire-based survey was implemented and targeted at the furniture, moldings, and builder’s joinery and carpentry sub-sectors, with the assistance of the relevant trade associations. A total of 477 responses were obtained, and it was found that digital technologies, such as computer aided design (CAD), computer numerical control (CNC), digital communication, digital marketing, and enterprise resources planning (ERP) systems, were highly adopted, but they did not significantly differ in terms of company size or product type. However, the rate of adoption was not uniform, as 5% of the respondent companies did not adopt any digital technologies. The study revealed that wood products companies adopted digital technologies that boosted their production and marketing, while those with limited DT adoption were more severely impacted during the pandemic.
