is the process of enlarging a hole that has already been drilled (or cast) by means of a single-point cutting tool. Boring is used to achieve greater accuracy of the diameter of a hole, and can be used to cut a tapered hole.
The cutter is placed in the spindle where it rotates. The workpiece then moves past the cutter so that chips may be sliced off. The act of cutting a workpiece on a mill is called “Milling”.

A fillet is a rounding of an interior or exterior corner of a part.Fillets give a part better flow and less resistance. Using a fillet also eliminates any sharp edges that can be easily damaged, or that could cause injury when the part is handled
A work-holding or support device used in securely locating and supporting a work-piece, ensuring that all parts produced using the fixture will maintain conformity and interchangeability
Feed rate is the velocity at which the cutter is fed, that is, advanced against the workpiece. It is expressed in units of distance per revolution for turning and boring (typically inches per revolution [ipr] or millimeters per revolution). It can be expressed thus for milling also,

Is a special type of recessed surface. In turning, it refers to a recess in a diameter. In machining, it refers to a recess in a corner. In molding, it refers to a feature that cannot be molded using only a single pull mold.
This is the first stage of machining where the object is to quickly remove the bulk of the waste material, normally with the aid of a ripper cutter. this gives the coarse stepped feature seen in the workpiece above.
This stage of machining generally uses a smaller cutter than roughing, typically an end mill, although the aim is still to remove the bulk of the waste material.
The next stage, using a relatively large ball nosed cutter, is to start to form the final profile of the workpiece, removing the steps generated in the two above procedures.
The final stage, and the longest process of all, is the final cut to the desired size. A small ball nosed cutter traversing across the surface produces the finished shape.
A type of cutter that used for the rapid removal of large amounts of metal, the serations along the cutting edge literally rip the material away. This cutter is designed to cut along it's sides only.
Similar to a ripper only without the serations, used for removing the bulk of the material. The cutting edges, like the ripper, are down the sides of the tool.
Typically this cutter has less cutting surfaces than the two above, and unlike the end mill and ripper can be used to plunge directly into the workpiece. As a result of the reduction in cutting surfaces there is better swarf removal meaning the tool can be used in enclosed pockets and slots.
This cutter, as its name suggests, has a semi-circular cutting face, with the aid of computer software it is possible to cut tangentially to the work piece enabling curved surfaces to be machined.
The milling process is removing material from a dedicated workpiece through rotary cutting. The cutter in a mill often has multiple cutting points, and generally moves perpendicularly on an axis, cutting with the tool’s circumference into the workpiece.

A device used in casting and moulding processes to produce internal cavities and reentrant angles of parts.
In engineering, draft is the amount of taper for molded or cast parts perpendicular to the parting line. It makes the act of de-molding easier.
A gate is a designed small opening to allow the liquid resin into the silicone mold cavity, a successful gate design is determined by part structure, size and location.

Is a chemical used to prevent casting resin parts from bonding to mold surfaces. So as to make the part easier to be taken out of silicone mold.
ilicone, by contrast, is a synthetic polymer made up of silicon, oxygen and other elements, most typically carbon and hydrogen. Silicone is generally a liquid or a flexible, rubber-like plastic, and has a number of useful properties, such as low toxicity and high heat resistance. It also provides good electrical insulation.

Shore hardness is a measure of the resistance of a material to the penetration of a needle under a defined spring force. It is determined as a number from 0 to 100 on the scales A or D. The higher the number, the higher the hardness. The letter A is used for flexible types and the letter D for rigid types.
