S
Sharp edge
The term sharp edge refers to a cutting edge that does not have any honing.
Shoulder milling
A machining process in which 90 deg walls can be achieved.
Side cutting edge angle
When turning, the side cutting angle refers to the angle between the cutting edge that enters the work in the direction of tool movement and a line perpendicular to the axis.
Sintering
A process of heating a material and bonding its powder particles or compressed powder particles.
Slotting
A machining method used for generating slots.
T
Table
Table refers to the base of a machine that is used to attach the workpiece to.
Taper collet
A taper collet is a collet that has its grip in a taper form.
Tapping
Tapping is a machining method in which threads are generated.
Tensile strength
Easiness to conduct heat.
Thermal conductivity
The value found by dividing maximum load applied on a material that is stretched until being cut by the material sectional area.
Solid end mill
An end mill with the cutting edge, neck and shank made of the same material (high-speed steel or cemented carbide).
Solution treatment
A treatment that is used to forcibly maintain an alloy element dissolved in a metal.
Spindle
A rotation axis of a machine, on which a cutting tool or a workpiece is mounted.
Straight collet
A straight collet is a collet that has a straight grip.
Surface treating
Consists of a number of processes in which chemical elements permeates into the workpiece. Coating however is a process in which chemical elements are applied onto the outer surface of the workpiece.
Swarf
Swarf is a term that is often used to describe the chips developed when machining is carried out.
Thermal Cracks
Separations in the cutting edge visible perpendicular to, and then parallel to the cutting edge due to thermal stress and thermal fatigue in interrupted cuts.
Tool post
A table to which tool holders or boring bars are fixed when turning.
Tooling
To prepare fixtures, cutting tools and cutting data that are necessary for machining.
Toughness
A property of being strong and not easily
broken by external force.
