Materials

we cut

Plywood is a modern wonder. And being in panel form makes it the perfect material for CNC routing/milling/machining. Take a look at our instagram for examples  of what’s possible with a 3-axis CNC and some plywood. YouTube is another great resource.

We’ve got some YT vids below to get you started.

Film face plywood
FORMPLY

Good value option for utilitarian projects. Low maintenance results.

Humility is a virtue

As well as being economical, composites, such as MDF, have great properties for CNC machining. Not having a grain pattern simplifies nesting / part orientation. Cut parts have good stability if properly treated (painted etc). And material thickness is reliably close to what’s on the label (nominal).

CAD Tips

for great results

USE LAYERS TO COMMUNICATE WITH YOURSELF ABOUT WHAT WHAT YOU’RE DRAWING

Some helpful tips:

Put the time in at the beginning to add and name the layers you’ll need.

Check your lines are on the correct layer by turning each layer’s visibility off one at a time.

Create a layer and name it “Archive”. Make it invisible. Instead of deleting lines you might want to reference later, move them to the archive layer for safe keeping.

As a rule, each toolpath (profile-through, pocket 6mm etc) should have it’s own layer.

THERE’S TWO SIDES TO EVERY WORKPIECE

Double sided cutting is achieved one of two ways:

Machine side A, remove from bed; Chuck some 3mm MDF on the bed. Cut out a suitable shape/template; Drop your workpiece in that cut-out, B-Side facing up.

Or with locating dowels, as illustrated. It opens up a lot of possibilities and can save a lot of labour down the track.

Get in touch to discuss which method best suits your job.

See the LOCATING DOWELS tab to learn more.

GRAIN DIRECTION

Nesting is the name given to arranging parts within your workpiece. Consider grain direction when nesting parts – it’s easy to forget when you’re at your computer.

Assume an East-West grain direction.

GAPS BETWEEN PARTS

Allow 20mm between nested parts and 20mm at the edge of your workpiece.

RADII ON YOUR RADAR

Every CNC router uses circular cutters. Circular cutters create square external corners. Internal Corners, however, will always have a radius. The radius will be equal to the cutter, as illustrated.

If this presents a problem for your job, get in touch to discuss your options. We’ve seen it all and we’re here to help.

Submit your job to be quoted and get a fixed price and delivery date.

WHAT DO THE CALLIPERS SAY?

Treat nominal thickness dimensions (what’s on the label) with caution. 18mm plywood is rarely exactly 18mm thick. It’s usually pretty close and 5% off in extreme cases.

MDF is typically closer to the nominal thickness than ply. Depending on the job this might be a key consideration.

Let us know if this has the potential to create issues for you. We have practices to mitigate the risks.

The Profile is simply the outline of the  desired shape. But there are a few things to keep in mind:

  • Sharp points and plywood tend not to get along – consider a rounded point or MDF
  • Allow 20mm gaps between parts – you can use the offset tool in your CAD program to check your spacing at a glance
  • Half the size of the cutting tool gives you your min. internal corner radius – see Internal Corners under CAD TIPS
  • The thickness of the material might limit cutter options – here’s what to expect ⬇️

Pocketing is one capability that separates CNC milling from laser or water-jet cutting. In this example pockets allow for backlit translucent acrylic.

  • Large Diameter cutters are used for clearing stock
  • Smaller cutters can subsequently tidy up pocket-profiles
  • Consider internal corners (radius) when CADing the complementary acrylic parts.
  • In this case a deeper pocket provides space for an LED lighting strip.

Including drill holes, such as pilot holes for screws, saves a lot of effort down the line. Drills can also be used to make locating holes – choose your hardware in advance.

  • 8mm Harron dowels are our favourite locators – available at Bunnings
  • Drills can be THROUGH or BLIND
  • CAD your Drills as a circle equal to the Drill diameter
  • Non-standard diameters can be achieved as Internal Profiles – eg for a 1″ dowel

We can order cutters on your behalf if you prefer.

We get asked this a lot by people looking for a 5-axis machine. But when we talk through the pros and cons of 3-axis vs 5-axis CNC machining our clients often decide 3-axis is the best fit for their needs. The primary benefits being reduced cost and simplified job set-up. Find more on this subject in our CAD Tips section.

Our machine can cut an area spanning 2400x1200mm and up to 100mm in height – landscape orientation for CAD. Complex jobs requiring the cutting of greater lengths can be achieved in two parts – 2700mm panels for example. We are not limited to cutting panels though. Get in touch to discuss the specifics of your job. Find more on this subject in our CAD Tips section.

We like to inspect every job to eliminate any potential snag before we start machining. The sooner we receive your CAD, the sooner we can give your job the green light. And, give you a delivery date.

Computer-Numerical-Control. Which basically means: if you can draw it in a computer you can make it. Over to you.

Our CNC machine is a 3-Axis, flat-bed with vacuum table and automatic tool changer. Built in Australia by MultiCAM – and serviced regularly.

No. We mill materials using router bits, which creates to potential to shape, pocket and drill. Just like there are twelve notes with which to compose music, this opens up a world of possibilities.

Plywood, Composites such as MDF or Chipboard; Solid wood in planks or laminated panels; A growing array of plastics. Follow this link for a comprehensive list, as well as the pros and cons of each.

Good question. Our machine secures the workpiece by a powerful vacuum. Workpieces smaller than 300x300mm can present a challenge. But we have ways to overcome those difficulties. Get in touch to discuss the implications for your job.

If you want to cut through ferrous metals such as steel the answer is probably No. We can point you in the right direction if CNC routing / CNC milling isn’t suitable for your job. We might be able to help you with something in the future, so we’re happy to make your acquaintance.

You’re welcome to submit any file type to get the ball rolling. We’ll let you know if something’s missing. 2D CAD files such as dxf or dwg are ideal for most job. We also work with Fusion360. Get in touch for answers to questions specific to your job. PDFs with drawings explaining your job are also welcome.

Head over to our section on layer formatting by following this link.

Everything in one file is okay. But it can be a good idea to create different files for different materials – such as plywood and planks OR different thickness panels. It can help to simplify your layers.
