RFID Radio Frequency Identification (RFID) is a technology where individual components (or partsin the case of manufacturing systems) are attached to high frequency read/write tags which allow Page 11.1274.6the product to be tracked along a system. This way the history of every product can be traced andstored in a database, allowing for part, process and person tracking and web-based monitoring of (a) (b) Figure 5: a) The Ethernet network and the various field buses; b) SafetyBus p network (a) (b)Figure 6: a) An
conducted trade studies. In the trade studies theylooked at different types of actuators, clamp actuators, injection methods, machine orientation, and machineoperation. Within each section they set up a table to compare the options available and set up a scoring system.By using a scoring system, it helped to identify which option would be the best for the application. The scoringwas done on a scale of 1- 4 with 1 being the least favorable and 4 being the most favorable, specifically accordingto their application. A copy of the trade study can be seen in Appendix B. In conjunction with the trade study,they looked to the survey results to see which options the trade studies yielded as the best fit, with whatequipment the educators had access to. For

Specking et al.

There are more similar commercial packages thatthe authors did not have an opportunity to evaluate, but the three packages give a good overviewof the “teaching assistant” type of online learning systems.

Various modulesand packages have been developed to enhance the online learning experiences via moreinteractive activities. Simulation and gaming are the main methods to achieve this goal. Puresimulation demonstrates a process or the operation of a system and may also provide data forfurther analysis. Using proper computer programs

If the hinge pattern is repeated a fewtimes horizontally, these rotations can accumulate into a large total bending angle.Figure 1. A. plain sheet of material for laser cutting. B.

The curvature limitbefore permanent deformation or failure (for a given thickness and material) is relatively small,so a desired total bend angle

innovative ways; and that requirea knowledge of standard operating procedures. Narrowly defined activities are those that involvelimited resources, that involve the use of conventional processes and materials in new ways, andthat require a knowledge of basic operating processes.For associate degree programs, these student outcomes must include, but are not limited to, thefollowing learned capabilities: a. an ability to apply the knowledge, techniques, skills, and modern tools of the discipline to narrowly defined engineering technology activities; b. an ability to apply a knowledge of mathematics, science, engineering, and technology to engineering technology problems that require limited application of principles but

The followinglearning outcomes based on the ABET criteria 3 (ABET- ETAC, 2018-2019) [3] have beenestablished to assess the student learning in this program. These student outcomes are asfollows: a) Graduates will demonstrate an ability to apply the knowledge, techniques, skills, and modern tools used in manufacturing engineering technology program. b) Graduates will demonstrate an ability to apply knowledge of mathematics, science, and engineering principles to analysis and design. c) Graduates will demonstrate an ability to conduct standard tests and measurements; to conduct, analyze, and interpret experiments
