Multiplex vs. plywood.
Both plywood and multiplex are often used in furniture construction, modelling and other areas. The similar properties of these two materials also require the same conditions when processing and milling plywood and multiplex.

Special features
This is important to note when milling multiplex / plywood
Milling plywood is quite straightforward if a few basic principles are observed. As long as the choice of milling cutter and the cutting and feed speeds are adapted to the requirements of the plywood.
Milling cutter for multiplex / plywood
For milling plywood with CNC machines, specialists recommend milling cutters with straight carbide cutting edges. These ensure particularly clean cutting edges. This is particularly important for the softwoods used for plywood or multiplex, as the cut edges fray easily. Only use sharp cutters, as blunt tools lead to overheating of the material.
Cutting speed
Regardless of the type of wood, always mill at a high cutting speed to prevent the cut surface from overheating. When selecting the cutting speed, be sure to consider the stability of the plywood router and its vibration behaviour. This is because both parameters affect the local tension of the routing tool. If this is too high, the router will break at too high a speed.
The right feed rate
The feed rate must be optimally adjusted to the cutting speed and the density of the wood. If there is an imbalance, soft wood can warp when milling plywood. Or unattractive burn marks may form, which reduce the quality of the workpiece or require extensive reworking.

Multiplex / plywood is just as suitable for the machining process of milling as wood and other materials.
When routing plywood, it is particularly important to choose the right router bit. Use cutters with two straight cutting edges for the CNC router. Spiral-toothed cutters are also suitable for conventional routers.
Spiral cutters are the ideal choice for milling plywood, but also for multiplex boards, as they only fray the top layer minimally.
Plywood is usually very soft wood and should always be clamped at the shortest point due to the risk of breakage. Clamping too tightly can leave unsightly marks.
A cutting speed that is too slow leads to discolouration due to overheating. The correct ratio of cutting and feed speed is therefore important.
