Turning is a machining process in which a cutting tool, typically a non-rotary tool bit, describes a helix toolpath by moving more or less linearly while the workpiece rotates.
Usually the term "turning" is reserved for the generation of external surfaces by this cutting action, whereas this same essential cutting action when applied to internal surfaces (holes, of one kind or another) is called "boring". Thus the phrase "turning and boring" categorizes the larger family of processes known as lathing. The cutting of faces on the workpiece, whether with a turning or boring tool, is called "facing", and may be lumped into either category as a subset.
Turning can be done manually, in a traditional form of lathe, which frequently requires continuous supervision by the operator, or by using an automated lathe which does not. Today the most common type of such automation is computer numerical control, better known as CNC. (CNC is also commonly used with many other types of machining besides turning.)
When turning, the workpiece (a piece of relatively rigid material such as wood, metal, plastic, or stone) is rotated and a cutting tool is traversed along 1, 2, or 3 axes of motion to produce precise diameters and depths. Turning can be either on the outside of the cylinder or on the inside (also known as boring) to produce tubular components to various geometries. Although now quite rare, early lathes could even be used to produce complex geometric figures, even the platonic solids; although since the advent of CNC it has become unusual to use non-computerized toolpath control for this purpose.
The turning processes are typically carried out on a lathe, considered to be the oldest of machine tools, and can be of different types such as straight turning, taper turning, profiling or external grooving. Those types of turning processes can produce various shapes of materials such as straight, conical, curved, or grooved workpieces.
In general, turning uses simple single-point cutting tools. Each group of workpiece materials has an optimum set of tool angles that have been developed through the years.
The bits of waste metal from turning operations are known as chips (North America), or swarf (Britain). In some areas they may be known as turnings.
The tool's axes of movement may be literally a straight line, or they may be along some set of curves or angles, but they are essentially linear (in the non mathematical sense).
A component that is subject to turning operations can be termed as a “Turned Part” or “Machined Component”. Turning operations are carried out on a lathe machine which can be manually or CNC operated.
Ask KO Lang guys paano maayos to, nangyari is nagflash ako Ng iphone x then Hindi successful Kasi nag Ka error so Yong phone naka stock Lang sa recovery mode. Ginawa KO nag try ako na I exit sa recovery mode using 3utools after nun Yong phone Di na madetect at Di nagoopen.
So eto. Bumili ako ng PC. After 1 Year at after ng 1 Year Warranty. Doon pa siya nagloloko. Is there a catch to it or tricks? Or just coincidence? Kapag I click yung power button. Hindi siya mag on agad tulad ng dati. Minsan naghihintay pa ako ng ilang minutes, from 1 to 5 minutes before. Pero...
January 1, 2024 marked the start of a new year, but it was extra special for a certain actor's fans: the OG Dao Ming Si aka Jerry Yan also celebrated his birthday! Most will remember having a huge crush on the actor, whose popularity spiked after starring in much-loved Taiwanese dramas Meteor...
Guys pa help naman, ano kayang solution dito. Hindi na kase nag power on pc ko matapos mag cut off ng kuryente habang nag bo-boot. Mula nung namatay hindi na siya nag work ulit kahit mag kuryente naman sa pwer cord. TIA
Ano po kaya sira nito? Black screen lang pagkabukas. On/off lang din gumaganang button sa remote. Kung sa PC parang OS ang tingin kong sira. Any help po pls
Hello guys!
Ano kaya gagawin ko dito? Yung pc ko kasi ayaw mag on ng CPU. Natry ko na yung unplug/plug sa mga cords pero not working pa din eh. Sana may makatulong sa akin. Salamat!
Hi! I can't seem to find the designated forum for Samsung Galaxy A03 so I'll be just asking here.
I recently flashed a stock rom on my device using Odin, but unfortunately after flash the phone is not turning on. Odin status was marked PASSED, didn't tick any other boxes except the default Auto...

Dati naman gumagana natunog tunog yong hard drive nililinis ko lang yong cable at hard drive unplug and plug gumagana Siya
Ngayon na stock nag matagal ayaw na mag on kaya tinanggal ko lahat at nilinis ko lahat
Ayaw na mag on 🤔
