About CNC Materials & Tooling
Selecting the right material and cutting tools is essential for achieving successful CNC machining results. Different materials require specific tooling, cutting parameters, spindle speeds, and machining strategies to achieve optimal surface finish, dimensional accuracy, and tool life.
Whether you're machining wood, plastics, aluminium, composites, or engineering materials, understanding tooling and material properties will help you improve productivity, reduce machining problems, and produce higher-quality finished parts.

Frequently Asked Questions
CNC machines can cut a wide variety of materials including wood, MDF,
plywood, plastics, acrylic, foam, composites, aluminium, brass,
and many engineering materials depending on the machine and tooling used.
An end mill is a cutting tool used for CNC machining operations such as profiling,
pocketing, contouring, and finishing. Different end mills are designed for specific materials
and cutting applications.
Single-flute cutters are often preferred for plastics and softer materials,
while multi-flute cutters can improve surface finish and material removal rates
in wood, aluminium, and engineering materials.
Straight cutters, compression bits, upcut bits, downcut bits,
and V-bits are commonly used for woodworking applications depending
on the desired finish and machining operation.
Yes. Many CNC routers and milling machines can machine aluminium successfully
when using appropriate tooling, spindle speeds, feed rates,
and workholding techniques.
Feeds and speeds refer to the cutting feed rate and spindle speed used during machining.
Correct settings help maximise productivity, improve finish quality,
and extend tool life.
Tool wear occurs naturally during machining. Excessive cutting forces,
incorrect feeds and speeds, abrasive materials, and poor cooling
can accelerate tool wear.
Poor surface finish may result from worn tooling, incorrect cutting parameters,
machine vibration, insufficient rigidity, or unsuitable tool selection.
No. Different materials require different cutter geometries,
coatings, flute counts, and cutting parameters to achieve the best results.
A compression cutter combines upcut and downcut geometries,
producing clean edges on both sides of sheet materials such as plywood and MDF.
Use appropriate feeds and speeds, keep tooling clean,
avoid excessive cutting loads, ensure proper workholding,
and replace tools before excessive wear occurs.
Yes. RoboSavvy can help you select suitable materials, cutters,
workholding solutions, and machining parameters for your CNC projects,
whether you're a beginner or professional user.
