Abstract. An orthogonal cutting is a symmetric cutting thus it can be modified as a two dimensional cutting. This paper uses quasi-steady molecular statics method to carry out simulation of two dimensional nanoscale cutting copper work piece by the diamond tools. For the two dimensional quasi-steady molecular statics nanoscale cutting model used by this paper, when the cutting tool moves on a copper work piece, displacement of atoms is caused due to the effects of potential on each other. After a small distance that each atom moves is directly solved by the calculated trajectory of each atom, the concept of force balance is used. The minimum energy method is employed to carry out the search, and obtain the new movement position for each atom. Based on the simulation results, this paper studies the chip formation shape and cutting forces in x direction and y direction.
Although robot has been around for many years, the programming language for robot control is still hard for ordinary persons. To promote robot into live of ordinary persons, an easier control language is one of necessity. We need a control language that can be programmed in any words and not limited to English. Forth is one of computer language that can define new commands in any printable characters on keyboard. This study explored eforth, one of kind of Forth, build on ATMEGA328P chip which is used on the world wide popular Ardunino UNO board is called 328eForth system. A 328eForth system has been developed that can be used to control hardware peripherals using Traditional Chinese command. It has simple programming rules, compact system size, and is an open source control language which used in robotic and mechatronic control and education for public.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
