Benefits
Improved, Uniform Cut Quality In addition to controlling the motion of the contouring axes of a laser cutting system the AMC can also be used to directly control the laser modulation, the laser pulsed output as well as the automatic height control axis (see the Height Control Unit specification sheet for details) in order to provide you with a uniform high quality of cut.
By connecting the analog output into the laser the AMC can automatically reduce the power of the laser as the axis slows down and increase the power as the axis speeds up. Modulation control therefore significantly reduces scorching of the material surface whilst also producing a more accurate component with superior edge definition. Laser Pulse Control Many lasers also allow external control of the laser pulse frequency. The AMC provides you with the ability to program a pulsed digital output (pulsed output type) which can be interfaced to the laser's external trigger input. On a system without Laser Pulse Control there will be motion quality problems caused by the fixed frequency pulse train. As the laser cutting axes slow down, say at corners, more pulses per inch/mm are produced, giving a wider cut. If the laser moves quickly, say along a straight line, fewer pulses will be produced per inch/mm, giving a thinner cut. The AMC can be configured to pulse it's output (hence the laser) in terms of the distance travelled and not time. So by using the AMC to control the laser pulses a consistent number of pulses per inch/mm will be achieved over the entire job resulting in uniform cut quality. Multiple Focal Lengths In some applications it is particularly useful to be able to preconfigure different focal lengths. This can be achieved on the AMC by assigning focal lengths to tool settings and then inserting a tool change into your job program. The AMC can then automatically adjust the laser head to the correct height above the material with the correct focal length. This ability to set multiple focal lengths allows you to produce a number of different depths or widths of cut on the same job without the need for operator intervention. Ease of Use The menu structure used to access the main functionality on the AMC cutter controller has been designed to minimise the number of key presses required by the operator to select and execute a job, making it easy for operators to use. The ability of the AMC to accept data in a number of different file formats allows your customers to use their favourite software package avoiding the need to retrain their operators. Event subroutines can be programmed into your controller to provide automatic shutter control, modulation on/off control and error monitoring using an input signal. The AMC controller can be provided with additional functionality ideal for laser cutting applications such as a shape library of standard parts, reverse through the program, cut recovery and kerf compensation.
