Commands for modifying dynamics (in an Amastone CNC machine)
for a better finish and shorter working times
Have you ever heard of the machine commands ERF=@R, ERF=@F or ERF=@N?
These commands are available in the standard set installed in an Amastone Next CNC router (thanks to the use of a highly professional control such as OSAI) and they allow you to change the dynamics of the CNC machine’s movements.
Knowing when to use these commands can make an enormous difference in terms of working time and finish quality of a stone-working operation.
In this context, dynamics signifies how the machine handles all curves and any change in direction. Hence, dynamics modifies the balance between speed and precision.
With a CNC machine, you can perform numerous types of stone-working jobs often very different from each other, from writing to engraving, and from cutting to 3D machining.
If you are a CNC machine operator, you must have had to favor precision over speed on some occasion whereas on other occasions you may want just the opposite without knowing how to do so.
With the commands in question, you can easily change the machine’s type of behavior and either optimize the working time or obtain a better-than-average finish.
You can execute these commands on the machine either as MDI (Manual Data Input) commands or directly within the processing ISO code. The machine can then automatically change its “character” (smoother or more nervous?) within the program itself.
I’d like to examine three commands in this article. Here they are in detail:
- ERF = @R
With this command, the value @R is assigned to variable ERF.
The letter R stands for roughing.
This command then sets the machine to roughing mode, maximizing the cutting speed.
- ERF = @F
With this instruction, the value @F is assigned to variable ERF.
The letter F stands for Finishing and with this command the machine will make movements in an extremely smooth mode, working on the curves and edges so as to obtain the best possible finishing quality.
- ERF = @N
If you want to compromise between machining speed and workpiece finish, the variable ERF can be assigned the value N which stands for Normal (normal balancing).
It doesn’t end here
These commands may also be calibrated accordingly as a function of special work requirements.
@R, @F, @N are in fact three numerical values which can be increased or decreased by software developers during machine configuration. This way you can increase or decrease the absolute level of accuracy and speed.
Obviously, in an amastone CNC router, technicians can modify these parameters remotely, even in the post-sales phase if requested by the customer for particular situations.
And you? Have you ever used these or similar functions to change your CNC machine’s working mode?
