Strategizing for 3+2 Machining by Thinking Three-Axis Aligning the drill at the correct orientation is accomplished in programming rather than on the shop floor with multiple setups and complex fixturing. Prototype work also benefits from this technique.ĭrilling holes at compound angles in a single setup is also an important benefit to 3+2 machining. In addition, 3+2 can help with machining certain types of parts from the solid rather than from a complex casting.

Curved or angled tube shapes within a workpiece such as ports on a cylinder head or ducts on a valve body often can be machined effectively with 3+2 if the CAM software supports this application. Any workpiece that creates challenging cutting conditions when using simultaneous 5-axis machining ought to be considered a candidate for 3+2 machining. Of course, applications are not limited to die/mold machining. (Adapted from “ The Value Proposition of Five-Axis Machining” by Barry Rogers) Five-sided machining eliminates these extra stoppages. This means that a part requiring machining on six sides may have to be moved by the operator seven times (load, reposition five times, unload). Unfortunately, whenever the operator must open the door of a VMC to flip or rotate the part for this purpose, or to load or unload the part, remove chips, or perform in-process quality checks, the spindle must be stopped. Most often, the process on a 3-axis VMC requires flipping the part or rolling it around from fixture to fixture to access all sides the part. All sides are accessible except the one resting on the table.

A significant advantage of 5-axis is being able to process five sides of a part in a single setup. The “5” in 5-axis machining refers to the number of directions in which the cutting tool can be oriented as it approaches the part surface.

Other benefits include shorter tool movements, fewer lines of program code and fewer machine setups. This means that a good surface finish and more accurate dimensional results can be achieved at a lower cycle time. Using a shorter tool, in turn, permits faster feeds and speeds with less tool deflection.

With 3+2, the spindle head can be lowered closer to the workpiece with the tool angled toward the surface. The main advantage of 3+2 machining is that it allows for the use of a shorter, more rigid cutting tool than would be permissible with conventional three-axis machining. Other names that appear are inclined, fixed or tilted machining, in reference to the characteristic angle of the cutting tool. This distinguishes 3+2 machining from continuous or simultaneous 5-axis machining. It is also called “positional 5-axis machining” because the fourth and fifth axes are used to orient the cutting tool in a fixed position rather than to manipulate the tool continuously during the machining process.
