Title:Engineering Workshop Practice
Long Title:Engineering Workshop Practice
Module Code:MECH6006
 
Duration:1 Semester
Credits: 5
NFQ Level:Fundamental
Field of Study: Mechanical Engineering
Valid From: Semester 1 - 2016/17 ( September 2016 )
Module Delivered in 2 programme(s)
Module Coordinator: GER KELLY
Module Author: GER KELLY
Module Description: The purpose of this module is to enable the student to have the practical skills for basic workshop practices e.g. Marking out, drilling, turning, milling and grinding. Learn to programme, setup and use CNC Machining Centres. The student will also have practical exposure to various welding and joining processes.
Learning Outcomes
On successful completion of this module the learner will be able to:
LO1 Comply with workshop safety regulations.
LO2 Identify and use marking out tools, handtools, measuring equipment, and perform a range of machine operations to produce a given project to specific tolerances.
LO3 Apply knowledge of welding process selection and capabilities.
LO4 Describe the principles of automated manufacturing processes. Setup and use CNC Machining Centre.
LO5 Programme CNC Machines using ISO/Heidenhain controllers.
LO6 Select and apply appropriate methhodologies to quality control and inspection of welded joints.
Pre-requisite learning
Module Recommendations
This is prior learning (or a practical skill) that is strongly recommended before enrolment in this module. You may enrol in this module if you have not acquired the recommended learning but you will have considerable difficulty in passing (i.e. achieving the learning outcomes of) the module. While the prior learning is expressed as named CIT module(s) it also allows for learning (in another module or modules) which is equivalent to the learning specified in the named module(s).
Incompatible Modules
These are modules which have learning outcomes that are too similar to the learning outcomes of this module. You may not earn additional credit for the same learning and therefore you may not enrol in this module if you have successfully completed any modules in the incompatible list.
No incompatible modules listed

Requirements

This is prior learning (or a practical skill) that is mandatory before enrolment in this module is allowed. You may not enrol on this module if you have not acquired the learning specified in this section.
