G code is used to control the movement of the machine while M code is used to control machine functions.

• G code is used for specifying the movement of the machine such as linear or circular interpolation.

• M code is used for activating or deactivating machine functions like turning on/off coolant or spindle.

• G codes are preparatory commands while M codes are miscellaneous commands.

• Example: G01 is a G code for linear interp...read more

Pulsed lasers emit high-power bursts of energy, while CW lasers emit a continuous beam of lower power.

• Pulsed lasers emit high-power bursts of energy in short pulses

• CW lasers emit a continuous beam of lower power

• Pulsed lasers are used for cutting, welding, and drilling

• CW lasers are used for medical procedures like laser hair removal

Acceleration is the rate of change of velocity over time, crucial in fiber laser cutting machines for achieving high cutting speeds and precision.

• Acceleration determines how quickly the cutting head can move along the material being cut

• Higher acceleration allows for faster cutting speeds without sacrificing precision

• Acceleration affects the quality of the cut edges and the overall efficiency of the cutting process

• Prope...read more

Jerk is the rate of change of acceleration. It is important in fiber laser cutting machines to control the movement of the cutting head for precision cutting.

• Jerk helps in controlling the acceleration and deceleration of the cutting head, leading to smoother and more precise cuts.

• It is crucial in preventing overshoot and vibration during the cutting process.

• By adjusting the jerk settings, operators can optimize the cut...read more

Absolute encoder provides unique position value for each position, while incremental encoder provides relative position changes.

• Absolute encoder gives unique position value for each position

• Incremental encoder provides relative position changes

• Absolute encoder is used in applications where exact position is critical, like robotics

• Incremental encoder is used in applications where speed and direction are more important,
