Their applications scope is wide, but their working principle is focused around calculation of vertical intervals.
The mechanism that allows this configurable accurate rotation is based on the movement of a worm-screw that is placed under the index table and can be turned by hand. Fixed axles that are positioned in intervals under the rotary table as driven from the worm-screw movement transforming it to rotational kinetic energy. A ratio between the the worm-screw and those axles is the factor that determines the maximum indexing resolution of the table.
Unique Milling Techniques
There is a very wide scope of possible uses for rotary index tables, and their various settings and configurations can deliver unique milling techniques that are only limited by the machinist’s imagination. One of the most notable uses for the rotary index tables is as an alternative to an actual lathe machine. This can be done by using a chuck to hold the object, a tailstock to set the center of the milling process and an electric motor installed on the table’s worm-screw.
Many also workshops use RITs for the milling of bolt head indented features of various shapes (octagonal, hexagonal etc). Operators calculate the intervals that are needed for the processing of these features and set the table accordingly.
Cutting & Drilling Uses
Rotary Index Tables are also used for cutting arcs of high precision and variable curvature. Through the addition of a compound table, the machinist can freely change the position of the center of processing, thus creating a gradually opening or closing arc.
RITs can also be used as supportive equipment in the cases of underpowered drillers that are used for the opening of large diameter holes at once. Rotary Index Tables can help such a driller to open multiple smaller holes that will constitute the large one. The end result is has the same level of precision with an one-time drilling.
Maybe the most demanding cutting process that index tables can help with is the realization of helixes. These three dimensional shapes are especially demanding as they require movement along at least three axis which is almost never possible by lathes alone. RITs come as a supplementary solution to this process, moving the workpiece rotational (two axis) while the cutting tool moves along the third axis thus creating the helix.
Maybe the most common use of the rotary index tables though is the drilling of equidistant holes on a circular flange. Using the tool for this purpose is an easy and straight forward activity that is only requires the calculation of the intervals based on the number of holes and their center to center distance. By re-positioning the flange in off-centric holes, one can further drill each hole into a larger one.

Functional neurology deals with affecting neurologic pathways or areas of the brain that are under functioning (A functional disconnect syndrome with regard to an Asperger's child). This assumes that there are no structural problems in the anatomy and children with Asperger's Syndrome are just this type of situation. Their neurological workup that might have included an EEG or an MRI is usually normal. Thus we are dealing with a functional lesion and not a hard lesion such as a tumor or stroke. It is the practicing functional neurologist job to localize or find out where the problem is in the nervous system. Along with a thorough neurological examination an in-depth history must be performed which includes motor development. The doctor should look for developmental delays such as delayed crawling, standing or walking which may signal when the problems began. Once the primary problem has been determined all secondary lesions and consequences of that primary lesion must be addressed. Hemispheric integration relates to the concept that usually these Asperger's children will have an underactive hemisphere and poor communication between the hemispheres. With Asperger's Syndrome children this tends to be the right hemisphere. Let us look at normal functions of the right hemisphere.
NORMAL FUNCTIONS: Right Hemisphere is responsible for nonverbal communication, math, reasoning, reading comprehension, spatial and attention. It controls impulsive behavior, feeling your own body, proprioception, seeing the big picture (Global Coherence), facial recognition, social skills, withdrawal behavior and getting stuck in any activity. Right hemisphere may also control fear, anxiety, immune suppression, low frequency sound and light, gross motor, eyes, posture, and big muscle rhythm.
Now let?s look at a paragraph from National Institute of Health. What is Asperger's syndrome?
Children with AS are isolated because of their poor social skills and narrow interests. They may approach other people, but make normal conversation impossible by inappropriate or eccentric behavior or by wanting only to talk about their singular interest. Children with AS usually have a history of developmental delays in motor skills such as pedaling a bike, catching a ball, or climbing outdoor play equipment. They are often awkward and poorly coordinated with a walk that can appear either stilted or bouncy.
Now back to the title of the article. Children with Asperger's syndrome are higher functioning along the autism spectrum. They are intelligent, so much so that they are known as the little professors. Th.
