See turning machine. Machining and measuring to exacting standards. Four basic considerations are: dimensions, or geometrical characteristics such as lengths, angles and diameters of which the sizes are numerically specified; limits, or the maximum and minimum sizes permissible for a specified dimension; tolerances, or the total permissible variations in size; and allowances, or the prescribed differences in dimensions between mating parts.

Machining vertical edges of workpieces having irregular contours; normally performed with an endmill in a vertical spindle on a milling machine or with a profiler, following a pattern. See mill, milling machine. Secures a cutting tool during a machining operation.

Basic types include block, cartridge, chuck, collet, fixed, modular, quick-change and rotating. Workpiece is held in a chuck, mounted on a face plate or secured between centers and rotated while a cutting tool, normally a single-point tool, is fed into it along its periphery or across its end or face.

Takes the form of straight turning cutting along the periphery of the workpiece ; taper turning creating a taper ; step turning turning different-size diameters on the same work ; chamfering beveling an edge or shoulder ; facing cutting on an end ; turning threads usually external but can be internal ; roughing high-volume metal removal ; and finishing final light cuts.

Performed on lathes, turning centers, chucking machines, automatic screw machines and similar machines. A little fluid in the wrong place on these and a host of other vehicles and machinery might create a life-or-death situation for operators and passengers alike.

Some fluid connectors come with O-rings, others with metal-on-metal seals, but all rely on a complex shape that is usually machined with a port tool. Port tools can be resharpened many times and, according to Wetmore Tool, may last decades. Photo courtesy of Wetmore Tool and Engineering. Nor are ports as complex as they initially appear.

Porting is not rocket science. However, the configurations are sufficiently complex that they would be extremely challenging to make on most machines without what is essentially a big form tool.

CNC lathes make it possible to shelve port tools in favor of a boring bar and CAM-generated toolpath. Still, port tools remain commonplace on machining centers, mechanical screw machines and even drill presses, where profiling the port shape is impossible.

Virtually everything is made on CNC machines today. Other port tools have also seen a decline in popularity. Kurtz said the company has a long history of manufacturing port tools, but much of the work has dried up as aircraft designers move away from specifying hydraulic control systems in favor of electronic ones.

As a result, Wetmore has redirected most of its development efforts into aircraft assembly tools, such as extension and core drills.

One of the biggest challenges with any porting operation is chatter.

This is good advice. They also last a surprisingly long time. Enderle applies SCT tools to port barrel valves, fuel shutoffs, fittings and other racing equipment components. Most of these are made of T6 aluminum, although Jones said Enderle machines some cast aluminum, which is somewhat abrasive. Another porting success story comes from Union, Ill. Brian Halwix Sr. For Halwix, the biggest challenge with port machining is breaking into cross-holes.

The machine FMS at New Dimensions produces a variety of aluminum and cast iron hydraulic manifolds for the agriculture and construction industries. Halwix said there are two ways to avoid this problem.

The first is proper part processing, particularly machining ports in the right order to avoid cross-holes in the first place. The next course of action is tweaking the tool design by adjusting flute margins and using other tricks of the porting trade. Hartland Cutting Tools Inc.

Call Achieves perfect concentricity since tools are ground between centers. Cutters are designed for balanced tip cutting and even distribution of chip load for maximum life between grinds. Tool life is also increased by form relieving cutting edges.
