Equipment / CNC Model Mill / Training
Contents
Roland Mill Training
This page documents the process for being trained to use the, and the list of members who have completed that training.
Summary
Training takes place in three main steps:
- Group Training of 1-4 members, going through the equipment and how to use it (~1hr)
- Individual Training Task, where an individual member is set a task to complete to prove and improve understanding (~30min each)
- Project Oversight, where more experienced users oversee the projects being undertaken when cutting (first 2-3 projects)
Training on the mill is run by the mill Owners. The mill Owners are a group of people responsible for maintaining and training on the mill, and hence have been trained to train, and trained to perform the weekly and monthly maintenance on the mill.
Booking
Sessions are advertised on http://meetup.makespace.org
- For discussing training, or requesting additional slots if needed, use the mailing list thread: Training : Roland Mill
Notes:
- You can only be trained if you have your name allocated to a slot (groups will be restricted to four at a time, so please don't make up additional spaces)
- You must do the group and individual training on the same day
Trained Users
The following members of Makespace are owners of the mill, so are trained to use and teach use of the Mill:
- Paul Osborn
- Peter Knight
The following members of Makespace are trained and qualified to use the Mill (note, they are not qualified to train others however): LIST MOVED TO PRIVATE LOCATION FOR GDPR
Training Cheatsheet
The training structure and prompt sheet. Please note, this is used by the Mill Owners as a prompt to ensure training is executed in a consistent and complete fashion; this does not constitute and is not a substitute for the training itself.
Group Training
The group training introduction structure, suitable for 1-4 members at a time in a 1 hr session.
Mill Basics
- Cover the basic mechanics of an 3 axis mill.
- Explain the difference between machine co-ordinates and user co-ordinates
- Cover the different types of cutters, ball, square etc.
- Explain collets and how to change the cutter.
- Cover types of materials than can be cut on the mill, wood, plastics, NO METAL
- Cover how to fix work piece to bed.
VPanel
- Show how to move cutter around in X, Y and Z free hand
- Show how to change the rapid speed, and explain difference between low/high and steps
- Show how to set XYZ origins.
- Show how to set Z origin using sensor.
- Show how to move to set co-ordinates and make relative moves.
- Explain how to switch to G-Code load G-Code files
Click Mill
- Explain how to do basic operations such as pocket and surface.
- Cover the basic cutting parameters, such as feed rates, spindle speed, cutting in amount and path interval.
SRP Player
- File formats that can be loaded (STL/IGES/Rhino)
- Rotating imported model to correct orientation.
- Scale model if needed.
- Cover type of milling
- Surface finish
- Flat / curved
- What cutting top or top and bottom means
- Adding supports
- Explain creation of tool paths
- Set the size of the work piece and material
- Create initial tool path
- Show cutting preview and explain how it can show cutting errors by flicking between model and preview.
- Show how to edit cutting paths, change tools and cutting area and depth.
- Show margins and slope and re-generate tool paths.
- Open and show the sample project 'thing.srp' as an example of how tool paths can be tweaked to reduce cutting times and optimize support material.
Cut 2D
- Open sample project to show basics of tool paths and 3D preview.
- Refer people to the videos on the Cut2D website.
Q and A
Individual Training Task
The individual task to get familiar, prompt questions and check understanding:
- Power machine on
- Change the current tool, demonstrating understand of the collet system and correct positioning of cutter in collet. Ensure that the cutter is not dropped.
- Position the cutter over the XY origin and set as origin in user co-ordinates.
- Set the Z origin using the sensor.
- Using the ClickMill software cut a 20x20mm pocket 5mm deep offset by 5,5mm from the origin.
- Pause the job midway through, then restart it.
- Clean machine.
- Turn off.
Project Oversight
For next 2-3 projects or until they are comfortable, projects should be machine out of soft materials only such as foam, that way if a mistake is made no damage will be caused to the machine and an expensive block of material lost. If possible the newly trained user should find another more experienced trained user to support them (second pair of eyes) in their first couple of projects, or any time they are unsure.
If in doubt ask for advice!!
