How does a cnc milling machine work?

Answer 1

A CNC laser machine utilizes a Computer to Numerically Control it. Common CNC language is called G-code (though roughly standardized, there are many forms). The CNC laser machine is different from the Windows driver or plotter style CNC machine that can laser engrave or laser cut directly from a third party design package like Corel Draw, AutoCAD, or Adobe Illustrator.

The G code of the CNC provides advanced control and more capability, and with this capability comes increased complexity and the need for more training. But the trade-off is worthwhile in a production environment where accuracy, quality and efficiency are paramount.

First, a drawing is made in a third party package such as AutoCAD or Solidworks, and exported in 2D format (dwg, dxf). A CAM packaged (Computer Aided Manufacturing) is utilized to enable the user to perform several functions that improve the accuracy, efficiency and quality of the laser cutting. For example, the user can decide to add a lead-in and tail-out for circle cutting or hole cutting. The laser pierces a hole in metal and the pierce creates a larger diameter hole that the cut line. So, rather than having circles with a notch where the laser pierced, the user pierces inside the hole (where the scrap is) and then cuts a lead in line to the circle then after finishing the circle cut leads out into the scrap area again. Other functions include setting the tool width and then compensating for the width of the laser cut line. This makes for higher accuracy in cut parts. Additional functions include setting cut order to minimize head up moves. In some cases, the user can specify gas or air assist pressures in the laser setup section at the top of the g-code.

After the setup in the CAM package, the G-code is generated. The G-code contains the motion commands and the laser commands to run the job. See http://www.2laser.com/bristol_series_-_metal_cutters for CNC laser machines.

the laser itself uses hea to cut throught the item of choice.it then uses mirrors to reflect the laser to percise aim and percision of where you want it to go. the laser itself uses hea to cut throught the item of choice.it then uses mirrors to reflect the laser to percise aim and percision of where you want it to go. the laser itself uses hea to cut throught the item of choice.it then uses mirrors to reflect the laser to percise aim and percision of where you want it to go. the laser itself uses hea to cut throught the item of choice.it then uses mirrors to reflect the laser to percise aim and percision of where you want it to go. the laser itself uses hea to cut throught the item of choice.it then uses mirrors to reflect the laser to percise aim and percision of where you want it to go. the laser itself uses hea to cut throught the item of choice.it then uses mirrors to reflect the laser to percise aim and percision of where you want it to go.

CNC machine systems are used for any process that is similar to a number of operations and movements. Some examples are sawing, picking and placing, routing, tape and fiber placement, sewing, fabric cutting, gluing, pinning, spinning, bending, flame and plasma cutting, ultrasonic welding, friction stir welding, welding and laser cutting.

Answer 4

CNC Milling machines work by using a computer to send signals to a stepper motor controller. This then tells the stepper motor (a device that translates electrical pulses into precise mechanical movement) which direction to turn and how many steps to take. The motor is connected to the drive mechanism of the mill in the X, Y and Z axes. Some CNC milling machines use a servo motor instead of a stepper motor, the advantage of this is that metal can be cut at high speeds and, due to a feedback loop, the machine always knows its exact position.

Answer 5

A cnc milling machine is a tool that is used to work and shape solid materials. The workpiece moved and shaped against a rotating cutter. Can be operated manually by hand or mechicanically automated.

The spindle axis is vertically oriented in the machine and milling machines are held in the spindle and rotate on its axis. The spindle can generally be extended to plunge cuts and drilling.

The Laser Cutter works by making the laser enter through the side of the material that needs to be cut. Find more info at http://www.topbits.com/how-a-laser-cutter-works.html
