Module Outline – Coursework Table project Purpose of the table project is to reflect your use of woodworking
machinery through wood processing safety and best practice Project enables you to purposely process material to construct an
artefact (table) from a raw plank state in the most efficient and safe manner possible
Use of the surface planer, thicknesser, rip saw, mortiser, bandsaw, panel saw as part of this project
Produce appropriate cutting lists, plans and procedures with the awareness of material processing waste, which is an important element for the sustainable use of material and procurement of bulk raw plank material for class projects
Develop hand skills in preparation for teaching practice by producing a series of hand-crafted joints to construct the table
Develop your awareness of machine safety through risk assessment procedures including aspects such as hazard identification and risk magnitude. This is a critical aspect regarding the safe operation of any second level technology classroom.

Table project requirements:1. Produce fully constructed and finished table
2. Produce an orthographic plan, elevation and end view of table showing component detail. Can be done using hand or CAD/Solidworks
3. Produce a cutting list for components
4. Produce a graphical procedure handbook of project material processing safety & best practice. Templates will be provided for this aspect.

Lab book: The purpose of the lab book is to record your in lab
exposure to wood processing safety and best practice.
It is advised that you complete the lab book during your lab time as it intends to capture your initial exposure to using wood processing machinery
You will not be permitted to the lab without your lab book
Lab book can be purchased from snap printing at a cost of €6.
Module Outline – Coursework Term Assignments:
Risk Assessments Create an A3 booklet to include the following:
Lab Machines:1. Risk assessment 1 – Surface planer2. Risk assessment 2 – Thicknesser3. Risk assessment 3 – Rip saw4. Risk assessment 4 – Bandsaw5. Risk assessment 5 – Mortiser 6. Risk assessment 6 – Pillar Drill7. Risk assessment 7 – Router You will each be assigned and required to perform 3 risk assessments of staged (hazard
induced) machines. This will account for 3 of your 7 individual risk assessments outlined above. In case of staged machines you will be provide with an image and scenario and you will be required to perform your risk assessment based on this information.
Information Poster1. Create an appropriately designed A2 laminated poster on an assigned machine.2. Must be accompanied by a user information sheet3. You must also develop a work activity sheet that addresses machine safety and best
practice to reinforce operant knowledge, understanding and safety culture
• All assigned machine lists, as discussed in both cases above, can be viewed in the lab.

WT4603
Module Outline – Coursework Lecture Worksheets: Each week you will be given an activity sheet to be
completed during the lecture. The aim of the lecture worksheets is to reinforce wood
processing safety and best practice. The worksheet will prepare you in advance of activities
taking place in forthcoming labs. It will provide you with a theoretical understanding of
wood processing safety and best practice that will strengthen your knowledge and understanding in preparation for labs.
The worksheets will also involve reflection on the use of machinery in previous labs

Department of Manufacturing & Operations Engineering
WT4603
Laboratory Sessions House Keeping Students have a responsibility for the care of the tools in their locker At thee beginning and end of the lab students must:
Check tools list and condition Report to T.A. if any tools are missing Report to T.A. if tools are damaged
At the end of each lab session: Benches must be brushed down Bench hooks returned to the underneath of each bench. Vices must be in the closed position. The floor area is swept and/or all waste material is removed from the ground area. Wood waste and paper waste to be segregated. If stools are used during a lab session, they must be removed from the floor and
placed on top of the bench. I.D. cards will only be returned to students when they have complied with these
regulations.

Department of Manufacturing & Operations Engineering
Health & Safety
Lab coats must be worn at all times in the workshop. Safety glasses must be worn at the appropriate times as
laid out by the T.A. in charge. Students must report damage to tools and equipment to
the T.A. in charge. Students must immediately report any personal injury
(nicks, cuts etc.) to the T.A. in charge. Failure to comply with safety regulations will result in
removal from the lab session. Any malicious damage to University property or
equipment will result in removal from the lab and University disciplinary procedures will be put in place.
WT4603
Department of Manufacturing & Operations Engineering
Lab Requirements – Week 2
Students must present at labs on Week 2 with the items requested on the 2nd Year Tools List
Failure to present this equipment at the beginning of the lab will result in you not being able to participate in the lab
You must bring all equipment & PPE to all labs

Step 1:Isolate machine
Step 2: Squaring guide fence•Set up surface planer guide fence @ 90⁰ to table surface•Note infeed and outfeed table. •Square to infeed using right angle square.•Use red lock handles to open and adjust fence.•Lock gently when fence is perpendicular to infeed table.
WT4603
Department of Manufacturing & Operations Engineering
Step 3: Setting infeed dept•This machine is calibrated in metric.•Maximum recommended material removal is 1-2mm/pass•Dept stop to be set at 2mm•Open infeed lock handle•Turn wheel to left to drop table to 2mm•Lower you drop, the more the planer cutting block is exposed•Close infeed lock handle when required dept is achieved.•* Do not adjust outfeed table level, this is for maintenance purposes only*

Step 4: Setting the guide fence width•Minimum blade exposure•Width of material + 10mm is recommended•This results in 10mm blade exposure - Safety•Adjust lock handle to wind in or out guide fence•Lock in appropriate position
242 + 10

Step 5: Guard adjustment•Guard set for face side = handle up – 10mm blade exposure•Guard set for face edge = handle flat – no blade exposure
WT4603
Department of Manufacturing & Operations Engineering
Step 6: Material Inspection•Inspect material for the following defects
•Cupping•Bowing•Twist•Knots•Loose grain
•Example - if material is bowed, set the bowed face to the surface planer table surface and process. Material should never be run through hump side down.
WT4603
Department of Manufacturing & Operations Engineering
Step 7: Determining face side and face edge•Use machine surface to check square•Select appropriate face side and face edge based on inspection•Preliminary surface marking using an ‘X’ with no less than a HB pencil•Ensure extraction gate valve is open and extraction is on•Proceed to plane material – face side and face edge only!
Gate Valve locate on extractor pipe just above surface planer

• Lab sequence – Thicknesser• Step 1:
1. Unlock twist release stop mechanism
2. Press green button to start
3. Allow machine to build up, this can be determined by noise consistency
4. When noise is consistent flip delta switch to on position
5. Feed rate, i.e. Speed at which material is passed, is set.
6. Adjust table height as required
7. Feed material as directed
