A machine can measure either from the zero point, or from the last position that was. For example, when you say "X10", you mean 10mm from the zero point of the axis X, or you may mean 10mm further than the last position the machine was on the X axis. The way of measuring is decided from the G codes G90 and G91. Running the G90 command, the machine will start to measure using absolute coordinates (measuring from the zero point of the axis) and running the G91 command will set the machine into "incremental measuring".

For making matters more clear, see the following two examples. They generate both exactly the same thing, a rectangle as shown in file p7.jpg. The first code example uses absolute measurements and the second uses incremental measurements. At this point it should be said that almost all machines measures by default using G90 (absolute coordinates). For the following example, we suppose that somehow, the machines start from point 10,10 and not 0,0

Difference in conventional and cnc machining?

conventional machining is that in which the control of removal of material is either by automatic machines or by man handled.while cnc machinig is that in which control of machining process is done by computes or through programming.

What is mean by conventional machining?

The two major categories of machining are "conventional maching" and "CNC (computer numerical control) machining." The actual metal cutting process is the same. The difference is in how the tool path is controlled as it cuts the workpiece. "Conventional machining" (also known as "manual machining") is generally regarded as using manually controlled machines, particularly lathes, mills and drill presses. The tool moves around the work by mechanical controls that are manually controlled. "CNC machining" is generally regarded as using lathes and mills (and some other machine types) in which all tool and workpiece motion is controlled by a computer.


What are the advantages of using a duplex milling machine?

These machines can rough machine both sides, at the same time, of a blank to "near finish" or "finish size" on the thickness of a blank. This cuts the time spent finish machining on a more expensive CNC machining center to perform the more complex machining characteristics of the part. Unfortunately, this increases handling time, setup time, and adds another move and probably another storage point to the process.

What is 5-axis CNC machining?

Five axis CNC machining is an advanced CNC machining technology that can perform cutting operations on multiple axes simultaneously to achieve complex shape machining. Compared with traditional three-axis machining, five-axis CNC machining has greater flexibility and accuracy. Five axis CNC machining is usually operated using a CNC machine tool with five independent motion axes. These five axes include the X axis, Y axis, Z axis, and two rotation axes, commonly referred to as the A axis and C axis. X. The Y and Z axes are responsible for linear movement, while the A and C axes are responsible for rotation. By simultaneously controlling the motion of these five axes, a five axis CNC machine tool can perform cutting operations in multiple directions, thereby achieving complex shape machining. This machining technology is suitable for workpieces that require cutting on multiple planes, such as curved parts, complex engraving, spiral shapes, etc. The main advantages of five axis CNC machining include: Complex shape machining: Five axis CNC machining can simultaneously perform cutting operations on multiple angles and planes, making it easier and more accurate to process complex shaped parts. Reduced process: Compared to traditional multi process machining, five axis CNC machining can complete multiple surface machining through one clamping and continuous cutting, reducing process and clamping errors. Improve production efficiency: the simultaneous cutting ability of five axis NC machining can significantly improve production efficiency and shorten Makespan. Improving surface quality: Through five axis CNC machining, smoother and finer surface quality can be achieved, reducing subsequent manual finishing. It should be noted that the five axis CNC machining technology is more complex than traditional three axis machining and requires a higher level of operation and programming skills. At the same time, the equipment and maintenance costs of the five axis CNC machine tool are also high. However, for applications that require high-precision and complex shape machining, five axis CNC machining is a very valuable technology.


What are the advantages of cnc over conventional machining process?

Computer numerical control (CNC) machining has many benefits over manual machining. To begin, CNC machining is more reliable and accurate because it does not rely on physical labor. With its multi-axis capability, simultaneous operations, and automatic tool changes, it improves production efficiency. CNC machines provide for more freedom of design because they can easily create sophisticated geometries and patterns. CNC machining also facilitates quicker production turnarounds, lowers labor costs, and makes part reproduction less labor intensive. CNC machining has many advantages over traditional machining techniques, including greater accuracy, repeatability, and overall productivity, and the ability to work with a wide variety of materials.
