MODULE 1 : Macro flow Control – Branching Control

ICAM Foundation Webinar Page 3

1.1. The “IF” statement

1.2. The “CASE” statement

MODULE 1 : The “IF” statement

statements…ENDOF / IF

IF / conditional_teststatements…

ENDOF / IF

Example:

IF/$T.EQ.1.OR.$T.EQ.10.OR.$T.EQ.20 $$ Tools 1, 10, 20INSERT/'G65 P1012'

ELSEIF/$T.GT.1.AND.$T.LT.10 $$ Tools 2, 3, 4, 5, 6, 7, 8, 9INSERT/'G65 P1016'

ELSEIF/$T.GE.11.AND.$T.LE.60 $$ Tools 11 through 60 except 20INSERT/'G65 P1015'

ELSE

ERROR/8,'Invalid tool number’ $$ Tools 61 and higher not availableENDOF/IF

MODULE 1 : The “CASE” statement

ICAM Foundation Webinar Page 5

Example:CASE/$T

WHEN/1,10,20 $$ Tools 1, 10, 20INSERT/'G65 P1012'

WHEN/2,THRU,9 $$ Tools 2, 3, 4, 5, 6, 7, 8, 9INSERT/'G65 P1016'

WHEN/11,THRU,60 $$ Tools 11 through 60 except 20INSERT/'G65 P1015'

WHEN/OTHERS

ERROR/8,'Invalid tool number' $$ Tools 61 and higher not availableENDOF/CASE

CASE / variableWHEN / const1, const2, const3… (or WHEN / start_value, THRU, end_value)

statements……WHEN / OTHERS

statements…ENDOF / CASE

MODULE 2 : Macro flow Control – Conditional Loops

ICAM Foundation Webinar Page 6

2.1. The “DO” loop

2.2. The “WHILE” loop

2.3. The “REPEAT” loop

2.4. Exiting loops (“EXIT”)

MODULE 2 : The “DO” loop

ICAM Foundation Webinar Page 7

Example:

DO / variable = start, end [ , step ]statements…

ENDOF / DO

the step argument is optional (if omitted, the default is 1) the variable value is iterated between start and end values all statements are executed on each iteration the loop ends when variable reaches the end value

DECLAR/GLOBAL,REAL,TOOLS(100)DO/I=1,100TOOLS(I)=-1

ENDOF/DO

DECLAR/GLOBAL,REAL,TOOLS(100)DO/I=100,1,-1TOOLS(I)=-1

ENDOF/DO

MODULE 2 : The “WHILE” loop

ICAM Foundation Webinar Page 8

Example:

WHILE/ conditionstatements…

ENDOF / WHILE

the condition is tested before each run (including first time) statements are executed as long as the condition is true the loop ends when the condition becomes false

DECLAR/GLOBAL,REAL,TOOLS(100),I=1WHILE/I.LE.100

TOOLS(I)=-1I+=1

ENDOF/WHILE

MODULE 2 : The “REPEAT” loop

ICAM Foundation Webinar Page 9

Example:

REPEATstatements…

UNTIL/ condition

the statements are executed at least one time (no testing of condition the first time)

statements are executed as long as the condition is false the loop ends when the condition becomes true

DECLAR/GLOBAL,REAL,TOOLS(100),I=1REPEAT

TOOLS(I)=-1I+=1

UNTIL/I.EQ.101

DECLAR/GLOBAL,REAL,TOOLS(100),I=1REPEAT

TOOLS(I)=-1I+=1

UNTIL/I.GT.100

MODULE 2 : Exiting loops (“EXIT”)

ICAM Foundation Webinar Page 10

Example:

EXIT/ number_of_levels

number_of_levels is a whole unsigned number (if omitted, the default is 1) each DO, WHILE and REPEAT counts as a level IF and CASE do not count as levels

DECLAR/LOCAL,REAL,I=0WHILE/I.LT.10J=0REPEATJ=J+1IF/J.EQ.12EXIT/2

ENDOF/IFUNTIL/$FALSE

ENDOF/WHILE

Example #1 : String and CL Records Matching

ICAM Foundation Webinar Page 11

1. Writing a header;

2. Ignoring unwanted work offsets;

3. Capturing a custom CL command to split

the motion of the first positioning move

according to the programmed value:

a. XY, then Z

b. XZ, then Y

c. YZ, then X

Example #1 : Solution

ICAM Foundation Webinar Page 12

In Machine Startup:$$ Header

PPRINT/'NC PROGRAM: !(A)',$FBASNAM($TAPEN,'.')

PPRINT/'POST NAME: !(A)',$PPFILE

PPRINT/'POSTED BY: !(A)',$FGETENV('USERNAME')

PPRINT/'DATE: !(A11)',$DATE

PPRINT/'DATE: !(A)',$FDATE('%x')

Example #2 : Incorrect program option and neutral CL data

ICAM Foundation Webinar Page 13

Define a set of user-defined macros to capture tapping cycles programmed using “per minute” feed rates (IPM or MMPM) and convert the programmed feed rates to the equivalent “per revolution” (IPR or MMPR) values.

Define a set of user-defined macros to limit programmed spindle RPM values to the maximum RPM available on the machine (stored in the system variable $MAXRPM). In case the programmed RPM exceeds the maximum, calculate the RPM reduction factor and apply it on all subsequent feedrates in the program (including canned cycles). Each new SPINDL instruction should update the RPM reduction factor (stored in a global variable). Also, when the spindle is turned off, the RPM reduction factor should be reset to 1.
