The same holds true for CNC machine programming. Even as new manufacturing technologies unfold, the fundamentals for how parts are machined with a CNC program will stay with you forever. At the heart of this automated manufacturing process is a set of instructions that tells a CNC machine where — and how — to move.

Even the latest CNC machines are the same at their core: they use an X, Y, and Z-axis to define the coordinate space inside the machine, and a tool sometimes an endmill, sometimes an extruder, sometimes a laser beam moves around that space. The technology might change, but the fundamentals remain essentially the same. Additive machines build a part from the bottom up. However, something like a milling machine has to subtract material away from an external object. To do this, the machine needs to understand the position of the stock in physical space. If only it were as simple as shoving a block of metal into your CNC and pressing go. Things start to get complicated when you add in a variety of milling tools.

In a technical sense the offsets are numbers stored in specific registers in the memory of the controller. The typical program run on a CNC machine tool contains a series of commands related to starting and stopping the spindle and moving the tip or the edge of a cutting tool through a series of points. Offsets are what lets the programmer write a program without setting up the machine tool first, in some cases without even knowing what machine tool will be used. Every machine tool will have a machine coordinate system. This is typically a Cartesian system with the z axis aligned with the spindle and x and y axes perpendicular to the z axis and each other.

Offsets are actually a platform for programming. And it does not require setting up the machine. In some cases, the particular machine tool is also unknown. This is actually a Cartesian system. But the main difference is that in this system, the Z-axis lies on the spindle, and the angle between x and y axes is 90 degrees. When a machine tool is in the initial stage, all of the axes are in a position of extreme travel. Tool offset is nothing but the specified values and measures we use to design a tool and shift the position of the tool.

Mike Lynch. The programmer chooses each origin, the position from which program coordinates are specified, based on how the workpiece is located during setup. This often involves time-consuming measurements using a spindle probe, dial indicator or edge finder. If the workholding device for a repeated job is qualified, these measurements need be taken only once. If not, the measurements must be repeated every time the job is run.

 Аукцион? - Сьюзан подняла. Стратмор кивнул: - Как раз сейчас японские компании скачивают зашифрованную версию Цифровой крепости и пытаются ее взломать. С каждой минутой, уходящей на эти бесплодные попытки, ее цена растет. - Но это же абсурд, - не согласилась Сьюзан.  - Ни один из новых шифрованных файлов нельзя вскрыть без ТРАНСТЕКСТА.

CNC machines use a 3D Cartesian coordinate system.
