Thermal printers are widely adopted in receipt issuance applications in distribution terminals including POS terminals and ECR, payment terminals, and financial terminals such as ATMs, CDs, and change machines due to their highspeed printing, easy maintenance, improved thermal paper conservation, and so forth. Furthermore, adoption of thermal printers is growing in label printing for distributi...

This paper was aimed at developing a computer aided design and manufacturing system for spatial cylindrical cams. In the proposed system, a milling tool with a diameter smaller than that of the roller, instead of the standard cutter for traditional machining process, was used to generate the tool path for spatial cams. To verify the feasibility of the proposed method, a multi-axis machining sim...

The prediction of chatter vibrations between the cutter and workpiece is important as a guidance to the machine tool user for an optimal selection of depth of cut and spindle rotation, resulting in maximum chip removal rate without this undesirable vibration. This can be done by some approaches. In this work, an analytical method is applied in which the time-varying directional dynamic milling ...

A forward and automatic method for in-process model generation is proposed and integrated with three-dimensional computer aided process planning (CAPP) system. The method based on feature cutter volume of manufacturing drives the in-process model to evolve from blank to part, which is coincident with the manufacturing process and ideology of process design. At the same time, technology of What-...

background: current who best infection control practices for injections do not address the use of hub cutters due to insufficient evidence on safety and efficacy. objective: to assess the impact of the use of hub cutters on 1) the frequency of needle-stick injuries (nsis) and other blood exposures among workers and 2) the volume of sharps waste in a mass vaccination campaign setting. methods: d...

This paper describes a numerically controlled finishing system, the Advanced Deburring and Chamfering System (ADACS). ADACS employs a user friendly, Graphical User Interface (GUI) to off-line program finishing and chamfering edges and prompt the operator for part cutting parameters. Given the operator-designated finishing and chamfering edges, ADACS extracts the features to generate a part fini...

Multi-component cutting force sensing systems in manufacturing processes applied to cutting tools are gradually becoming the most significant monitoring indicator. Their signals have been extensively applied to evaluate the machinability of workpiece materials, predict cutter breakage, estimate cutting tool wear, control machine tool chatter, determine stable machining parameters, and improve s...

5-Axis machining has been widely used in manufacturing of complex ruled geometries in automobile, aerospace, energy, and mould industries. Compared with traditional 3-axis machining, this machining operation offers better shaping capability and productivity with additional degrees of freedom in the tool motion. Tool path planning is a challenging task in most 5-axis machining operations, with t...

Food insecurity, price volatility and under-employment of rice farmers in Liberia are key drivers for the development farming machines locally. This project work aims to design fabricate a simple, low-cost, efficient mini harvester powered by solar panel translating learnt concepts principles engineering into physical workable harvester. A circular blade cutter, DC motor, battery cells main com...

A virtual reality machine shop environment was developed for the determination of critical quantitative and qualitative machining process parameters. Material removal and milling machine axes kinematics are simulated in real time. The G-Code program serves as the input to the system. A graphical model for the calculation of quantitative data affecting the machined surface roughness was develope...
