Aluminum 6082 (CNC) has very similar composition and properties to 6061, with slightly higher tensile strength. Compliant with British Standards.

Aluminum is a relatively easy metal to machine which makes it great for CNC machining. Aluminum has useful properties for machining such as being lightweight, malleable, tractable and overall good durability. It being so light and easy to work with means that it can be used for a wide variety of applications. CNC machined Aluminum parts begin as a raw piece of metal which is cut down bit by bit to create a desired shape or object. This process is done most accurately with a CNC (Computerized Numerical Control) machine which can produce almost any three dimensional object designed via CAD (Computer Aided Design) software.

Circular tools require an end cutting edge angle relief, usually between 10 and 15 degrees. The angle should be reduced as the depth of cut increases on larger diameter work-pieces to around 5 degrees, to avoid tool deflection. These smaller angles can result in some burr being left which may have to be trimmed off with a second cut. ‘Above centre’ distances should about 3mm.

Either blade or circular tools can be used. Circular tools are more rigid and provide a better heat sink capacity than blade cutters and so are generally preferred for parting-off stainless steel, where sufficient cut depth is allowed by the tool geometry. Circular tools are also better for interrupted cuts as the tool passes through details like drilled holes. Back rake angles should be between 6 and 10 degrees.

The cost of CNC machining Aluminum depends on the complexity and size of the part and the type of Aluminum. These variables will affect the type of machine that is required, the time it takes to produce the part and the cost of the raw material.

Back rake angles should be between 4 and 10 degrees. The smaller angles suit secondary cuts in multi-cut operations. The larger angles suit single cut operations or the primary cuts of multiple cut operations. Top face and back rake angles should have a smooth polished finish to avoid chip flow problems that can result in poor finish or overheating due to poor access of coolant to the cutting edges. Side relief and clearance angles should be between 1 and 5 degrees. The deeper the cut, the larger the angle. ‘Above centre’ distances should about 3mm.

End relief angles should be between 7 and 10 degrees and should be ground flat to provide maximum support for the cutting edge. Side relief angles should be between 2 and 3 degrees. For large cut depths larger the side relief angles may be needed to avoid tool seizure.

CNC Aluminum machining is a manufacturing process that involves cutting a piece of raw Aluminum until a final desired shape or object remains. CNC machines cut unwanted geometries away from a raw block of Aluminum using a CNC (computer numerically controlled) milling tool. These machines are very precise, allowing for high accuracy and part complexity.

Aluminum 7075-T651(CNC) is an aerospace-grade material with excellent strength-to-weight ratio and strength and hardness comparable to steels. T651 is the temper of Aluminum 7075, and to achieve this temper, the alloy is solution heat-treated, stress relieved, and then artificially aged.

The surface speeds shown for the different tool types are at the set depths of cut and feed shown. If depth of cut and feed are increased, the speed must be reduced. Alternatively for increased speeds, reduce the depth of cut and feed. For austenitic steels, (e.g. 304, 1.4301), the depth of cut must however always undercut the induced work hardened layer, so increase in speed must be carefully limited. Similarly, it is important to leave enough steel on the surface when completing the last roughing cut to enable sufficient finishing cut depth. Where this is impractical, a carbide tool used at high speed, low feed and a shallow depth of cut is an option.

Form turning stainless steel should allow sufficient material to be removed to avoid surface work hardening problems. This applies to both primary and secondary cuts in multi-cut operations. Feed must be maintained as the tool enters the work-piece. For form tool turning deep or complex shapes, slower speeds should be considered. The flow of cutting fluid, (coolant), must be carefully controlled to ensure that a consistent, large flow volume is delivered to the cutting edges at all times during form tool turning of stainless steel.

Too high a speed can result in tool tip burning. Too low a speed can result in chip build-up on the cutting edge. As a general rule, when there are cutting problems adjust the speed first and then, where necessary, the feed second.

End and side relief angles must be ground flat, without any concavity. Concave faces reduce the support at the cutting edge and can result in chipping or breaking.

Traditionally high speed steel (HSS) tools have been used for most turning operations, but carbide tipped tools are now also used. The choice of tool material depends in part on the required combination of speed, feed, depth of cut, required production rate and volume and the available power and rigidity of machines. This article gives suggested feeds and speeds for single point, form tool and cut-off (parting-off) tool geometry turning taken from the BSSA Stainless Steel Specialist Course Training Note No.9 ‘Machining Stainless Steels’.
