Unit of Competency MEM04017 - Develop and manufacture gear, conveyor screw and propeller patterns
Description
Employability Skills
Learning Outcomes and Application This unit of competency defines the skills and knowledge required to manufacture patterns for all types of cast gears, conveyor screws and marine propellers using a full range of materials. Gear patterns may be segmented or any other method used to minimise timber shrinkage or warpage to achieve the required strength.Conveyor and marine screws may be built up using predetermined thicknessed timber, either over a mandrel or a layout. Patterns may be set up on a joint board or plated for ease of moulding.Where the assembly of plated patterns is required unit MEM04012 Assemble plated patterns should also be selected.Where the selection and use of precision measurement is required unit MEM12003 Perform precision mechanical measurement should also be selected.No licensing, legislative or certification requirements apply to this unit at the time of publication.Band: AUnit Weight: 4
Duration and Setting X weeks, nominally xx hours, delivered in a classroom/online/blended learning setting.

(add new lines for each of the assessment tasks)

Assessment Tasks

Copy and paste from the following data to produce each assessment task. Write these in plain English and spell out how, when and where the task is to be carried out, under what conditions, and what resources are needed. Include guidelines about how well the candidate has to perform a task for it to be judged satisfactory.

This field allows for different work environments and conditions that may affect performance. Essential operating conditions that may be present (depending on the work situation, needs of the candidate, accessibility of the item, and local industry and regional contexts) are included.

Material includes one (1) or more of the following:

hardwood

softwood

epoxy resins

composites

Pattern parameters include one (1) or more of the following:

pitch circles

pressure angles

tooth form

left and right hand flight helix

pitch axial dimensions

angles

tapers

clearances

contraction allowances

Copy and paste from the following performance criteria to create an observation checklist for each task. When you have finished writing your assessment tool every one of these must have been addressed, preferably several times in a variety of contexts. To ensure this occurs download the assessment matrix for the unit; enter each assessment task as a column header and place check marks against each performance criteria that task addresses.
