Fanuc Macro Programming Series - Part #6 - Video Tutorial #1

They say the best way to learn is to see it in action. So this post we have a real treat in our Fanuc Macro Programming Series.

This post you get to listen to my "lark like" voice explain the method of assigning variables values and the building of a simple macro program to engrave (2) squares. It's not about the machining ... it's about the building and structure of the macro program.

It should be helpful in getting started down the road to building your macros, growing in complexity. ENJOY !!! ... but make sure you understand what's happening here so we can move on in later posts.

Fanuc Macro Programming Series - Part #5 : Arithmetic Functions / Control Commands

The power of the Custom Macro language lies in the use of a variety of arithmetic functions within the custom macro body. This features gives the user the power to re-define and re-calculate the values of variables "on the fly." This post is meant as a brief explanation and overall view of some of these functions available with a more in-depth view given in following posts in this series.

Types of Commands Available 

Definition and Substitution
( #100 = #101 )

Addition and Subtraction
( #100 = #101 + #102 )
( #100 = #101 - #102 )

Multiplication and Division
( #100 = #101 * #102 )
( #100 = #101 / #102 )

Logical Sum -- Exclusive OR -- Logical Product
(  #100 = #101 OR  #102 )
(  #100 = #101 XOR  #102 )
(  #100 = #101 AND  #102 )

Trigonometric Functions
( #100 = SIN(#101)) ----- Sine
( #100 = COS(#101)) ----- Cosine
( #100 = TAN(#101)) ----- Tangent
( #100 = ATAN(#101)) ----- Arc Tangent
( #100 = ASIN(#101)) ----- Arc Sine
( #100 = ACOS(#101)) ----- Arc Cosine

Other Mathematical Functions
( #100 = SQRT(#101)) ----- Square Root
( #100 = ABS(#101)) ----- Absolute Value
( #100 = BIN(#101)) ----- Conversion from BCD to BIN
( #100 = BCD(#101)) ----- Conversion from BIN to BCD
( #100 = ROUND(#101)) ----- Rounding Off
( #100 = FIX(#101)) ----- Discard fractions less than 1
( #100 = FUP(#101)) ----- Add 1 for fractions less than 1
( #100 = LN(#101)) ----- Natural Logarithm
( #100 = EXP(#101)) ----- Exponent with base
( #100 = ADP(#101)) ----- Addition of

Another powerful feature of the Custom Macro language is the ability for the user to control the flow of the programs execution. Using a variety of what is called CONTROL COMMANDS, the user can repeat areas, jump to areas and set conditions for program execution.Again, presented here is a brief explanation and overall view of some of these functions available with a more in-depth view given in following posts in this series.

Types of Control Commands Available 

DIVERGENCE
IF < condition> GOTO N----
When the <condition> is satisfied, the program execution jumps
to sequence number N----.
Example : IF [#100 = #102] GOTO N100

CONDITIONAL EXPRESSIONS EXPLAINED
The following are expressions that can be used to define conditional expressions :
EQ = equal to
NE = not equal to
GT = greater than
LT = less than
GE = greater than or equal to
LE = less than or equal to

ITERATION
WHILE < condition> DO <number>
......
END <number>

While the <condition> is satisfied, the program executes blocks between the WHILE statement and the END statement.

Example : 
WHILE [#100 LT #102] DO 1
( program commands )
( program commands )
( program commands )
#100 = #100 + 1 ( add 1 to #100 at the end of each body run )
END 1

BRANCH COMMAND
GOTO N----

Program execution jumps to sequence number N----
Example : GOTO N101

Being well versed in the information from this post will be a big help as we go forward with some macro programming examples in future posts.
