These steps must be accurately checked and rechecked to avoid any error slipping through.Crashes are often due to the following errors caused by the CNC Operators:- Lack understanding of CNC motion in use- Lack understanding of Spindle travel reference- Lack understanding of CNC coordinates- Lack understanding of Zero position- Lack understanding of CNC axes travel limitsHere are few tips to help you to quickly check before running any CNC to manufacture a part. But all CNC machines have two or more directions of movement or axis, this means the more axis the machine has the more complex the CNC machine,hence a 3-axis milling machine is considered to be less complex than a 5-axis milling machine.e the machine coordinates systems and the work coordinates systems. The location of XYZ machine origin within the machine may be different depending on the machines manufacturers.A CNC Operator or Programmer must know the total limits that each machine axis is allowed to move, in general this depends on the manufacturer of the machine.
A CNC Operator must not confuse between the two coordinates systems i.- A CNC Operator is responsible for placing the part onto the table and making sure the setting of XYZ axes to the datum are recorded and stored into work offset registry ( i.e G54 TO G59 in Haas machines) this will enable the part to be manufactured to be located at any point within the table by simple setting the x and y value to zero than machine zero ( i. It is therefore the reference coordinate system from which all else is referenced.It must be noted that each machine has different methods to be Home. Hence it is advised to check the machine manufacturer's catalog for precise instructions. The order of the axis movement is set by the machine manufacturers.- Zero position,this command zero all axis i.e G28 or G29 in Haas machine ).
