What is a macro in Fanuc?

Macro programming is a method using variable data is a special subprogram (now called a macro), with actual values defined in the main program. This method provides a single ‘master’ program that can be used many times with different numerical values. A typical example is a bolt circle, where only a few values change.

What is Fanuc custom macro B?

Master CNC macro programming. CNC Programming Using Fanuc Custom Macro B shows you how to implement powerful, advanced CNC macro programming techniques that result in unparalleled accuracy, repeatability, flexible automation, and enhanced productivity.

What is G65 Fanuc?

G65 code runs macro program with number, programmed in P parameter. Up to 21 local variables could be sent to the macro through A-Z parameters. In a screenshot is shown peck drilling cycle (G83) repeated in a line by running G65 with macro O9911.

What is a CNC macro program?

CNC Macro programming is sometimes thought of as a bit of a black art in CNC programming. Macro programming is sometimes known as parametric programming. It means you are controlling a program by external parameters.

What is parametric programming in CNC?

The parametric programming of CnC machine tools is a type of programming, in which controlled axis positions, feed functions and velocities will be defined in the program as parametric expressions [1]. introducing variables in a parametric form to the program allows the program being created to be made more flexible.

What is the difference between subprogram and main program in CNC?

Subprograms are normal CNC programs which are called from a program (normally called main-program) to add some kind of repeatable machining operation. For Sub Programming No Extra Skill Required CNC machinist/ CNC programmer not have to learn a new G-code or programming style.

What is G65 G-code?

– G65 G-Code is a Macro Call, whereas M98 G-Code is a Subprogram Call. More on macro calls in a minute. – Some controllers allow the M99 G-Code to return to a particular line instead of just returning to where the subprogram was called.

What is macros in CNC?

Is macro a programming language?

Image’s built-in macro programming language can be used to automate complex or repetitive tasks. Macros are similar to Pascal procedures, except the procedure keyword is replaced by “macro” and the procedure heading is a text string that becomes a command in the Special menu when the macro is loaded.

What is M99 in Gcode?

M99 is used at the end of a subprogram, local subprogram, or macro to return back to the main program. An M99 Pnn jumps the program to the corresponding Nnn in the program. An M99 in the main program causes the program to loop back to the beginning and execute until [RESET] is pressed.

What is P and Q in CNC program?

P = Sequence number for the start of the program contour. Q = Sequence number for the end of the program contour. U = Finishing allowance in X. W = Finishing allowance in Z. F = Feed rate.

What is Fanuc Macro executor?

FANUC MACRO compiler and library to create customised functions and programs. – Fanuc Your powerful programming language for machining or machine management purposes, the Macro Executor function converts, loads and executes custom macro programmes (P-CODE macro) into F-ROM (CNC Flash Memory).

What is macro executor in CNC machine?

Other NC programs, such as machining programs, evolve during machining. The Macro Executor function can convert a Custom Macro program created by the machine tool builder to an executable macro program, load the executable macro programm (P-CODE macro) into F-ROM (CNC Flash Memory), and execute it.

What is Gege Fanuc Series 18?

GE Fanuc Series 18 is an advanced CNC PMC C Macro Executor Custom Macro C Language Executor Open System CNC Part Program Storage (max) Extreme reliability in CNC machining – .Extreme reliability in CNC machining Series 0 i/0i Mate-

What is the difference between macro compiler and macro executor?

The function which converts a Custom Macro program to an Executable Macro program is called the Macro Compiler. The function which reads and executes a P-CODE macro is called the Macro Executor. The Macro Library is part of the CNC Application Development Kit.
