Engraving machine mechanical origin and origin of the workpiece, respectively is to point to what, what is the difference between a - - 【 】 Engraving machine _ _ _ _ CNC engraving machine woodworking engraving machine

the workpiece origin of engraving machine and mechanical origin are two concepts, the mechanical origin refers to the machine X, Y, Z three directions of the limit position, there is only one; The workpiece origin can any position setting in the machine, save more.





mechanical origin





carving machine is controlled by the CNC system of mechanical unit, the system itself only know the current position relative to the previous position, need to select a reference point, make an arbitrary place on the machine tool has a fixed coordinate as a parameter, the reference point is the mechanical origin.





engraving machine mechanical origin of how to set the





with limit can back to the mechanical origin, or it will crash. D macro system operating points back inside the mechanical origin is ok.





the workpiece origin





the workpiece origin refers to the workpiece coordinate origin, is for the workpiece size programming to determine the origin. Origin of the workpiece can be chosen by programmers, generally is the starting point for the workpiece machining. Option, the tip will automatically return to the origin of workpiece, from the current position point will be active when bearing back to the origin of workpiece.





specific back to zero method





1, if at the end of the Z direction Z direction coordinates, coordinates is greater than the starting point is the Z axis to feed alone to end the Z axis bearing, and then, the X, Y axis linkage, arrived in intent.





2 Z direction coordinates, and if the end is less than the starting point coordinates Z direction, X, Y axis linkage arrived first intention point X, Y coordinates, and then, the Z axis feed alone to end the Z axis.





because at the end of the machining of Z coordinate often in appearance, in order to prevent the point back to the workpiece zero after the workpiece appearance or bruised point, in fact, can not return to zero, the Z axis and a above zero offset value. The value of 'window' of processing parameters in the system parameters 'return point' setting.





after carving machining closed don't work back to the origin cause and solution to





1, limit switch, now of the engraving machine basic with a limit switch, limit switch is damaged.


2, d macro card is damaged.


3, in the DSP controller parameters are correct.


4, check the mapping file problem, change a file to try whether the procedure of problem


5, after carving the closed d macro press F7 DSP press confirm to see if can return to the origin of


6, from the control card to the limit switch wire have a virtual or short circuit


7, or not is generated by the program. G28 back to the reference point of instruction to the workpiece origin? Operation no back is off the pulse.


8, carrying on the system can set the processing is completed work back to the origin or in situ, or back to the designated parking spots.





power ( Point) Memory





in ideal case, the boot back before processing mechanical origin, will not affect the precision of the machine running. If appear in processing power, abrupt stop, beyond the collision accident, restart the machine to continue processing will offset, it becomes difficult to find the processing position just now.





engraving machine boot back after mechanical origin, is to determine the position of the workpiece coordinates relative to the mechanical coordinates. So in the process of processing power or tight stop, back in through the mechanical origin will find work coordinate system and this will ensure the accuracy of continue to processing, also is what we call electricity ( Point) Memory function.
