What is Fanuc custom macro B?
Custom macro B is FANUC’s version of parametric programming. Judging by the questions, comments and suggestions I regularly receive from readers, it is a feature that many of you have utilized. There are certain questions that I receive on a pretty regular basis.
What is macro Fanuc?
In many ways, Macro Programming is the highest level of G-code Programming. It offers the most flexibility and the greatest potential power of any of the G-Code Programming Techniques. Without Macro Programming, G-Code is not really a full fledged computer language, it’s more a recording of a series of manual steps.
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 canned cycle in CNC programming?
A canned cycle is a combination of machine movements that perform machining operation like drilling, milling, boring and tapping. This cycle simplifies the program by using a single block with a G-code to specify the machining operations usually specified in several blocks. This cycle is also called as fixed cycle.
What are CNC macros?
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 custom macro?
A custom macro is a query that you create using an macro expression, raw SQL, or raw SQL that includes a value. Custom macros support the use of variables. Creating custom macros. Macros that you create are available when configuring processes in a flowchart and defining derived fields.
What is P and Q in canned cycle?
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.
What is G73 in Fanuc system?
G73 tells the machine that we wish to use the pattern cycle. The first ‘U’ word defines the depth of cut of each roughing pass in the X-axis. ‘W’ is the amount that we wish to cut in Z-axis. The R is the number of passes we require.
What are the disadvantages of macros?
The disadvantage of the macro is the size of the program. The reason is, the pre-processor will replace all the macros in the program by its real definition prior to the compilation process of the program.
Can you use variables in G-code?
Like all programming languages, G-Code had the ability to use variables within our programs. Variables give us the ability to store information that we can later recall.
What can FANUC do for CNC macro programming?
Here’s just a smattering of the specific features it has that are a tremendous help when CNC Macro Programming: Handles the Fanuc Macro B syntax, the most widely used CNC Macro Programming syntax in the world. Graphical backplot makes it easy to see what the tool motions are:
Why custom macros for CNC?
Just about every facet of a CNC environment can be enhanced by incorporating methods afforded by custom macro. Students learn the benefits of custom macro application and how to implement improvements when applications are found.
Which macro programming dialect does FANUC support?
A word about Fanuc Macro B. Fanuc Macro B is by far the most common Macro Programming Dialect. Not all controllers support full Macro B, and there are variations supported by some non-Fanuc controllers.
How many variables are there in Fanuc Mach3?
Fanuc Macro Variables: Note that these ranges may vary across controllers and especially for non-Fanuc controllers! Mach3 has 10,320 variables available, from #0 to #10320. There’s not quite the variety found in Fanuc, but still, plenty of system variables are accessible so you can get at things like work offsets.
