Programming CNC Macros - Part 2

[@zhuangzhenggarygao4662]

Great video! can we see more macro videos? they are so useful!

[@CamInstructor]

I do like to throw in macro videos every so often and I think we are due for another. Keep an eye out for one soon! Glad you like them!

[@naserkh5865]

@@CamInstructor first of all thank you for your video which i like so much and i still waiting for your next one as soon as you can . thank you again and God bless you and your family .

[@CALLRICKY]

Waiting on another video please they are awesome!

[@MykiTFB]

Great video! After 10 years of Heidenhain Machining centers I have to pick up fanuc turning. I can't put it into words how useful this video is for me right now!!! Is part 3 out?(The follow up video)

[@mo000138]

太好了，想學習更多，謝謝

[@brianna110693]

I really like the information in this video, I am new to trying macros right now I have to manually rough face mill plates I would like to have a macro program set up in my fanuc control where I can just change plate size and run face milling quickly

[@CamInstructor]

Have a look at this video, I do a macro for facing in it... kzbin.infojXE4ZCv6yiM

[@marioaguilar2529]

can you adjust the A axis using a probe and how would you write the program. any lead would help. thank you in advance

[@CamInstructor]

You can do pretty much anything you can imagine with macros. There is too many questions that need to be answered from your statement whereas I cannot write a simple step by step for you. Basically, depending on what you want to adjust, probe the surface, record the location, manipulate that data to suit, write that data to where it is needed.

You have #9 as F, Would that be #6? or did I miss something... Love your tutorials!

[@CamInstructor]

No. Oddly enough, F is #9. You need to refer to the machines user manual to see what letters align with what variable number. Some follow the alphabet numbering, some do not.

[@ddenterprisesghagga]

Which software is this???

[@CamInstructor]

Cimco Edit. You can download a 30 day trial from their website if you want to check it out.

@@CamInstructor thankew sir

[@muraliyuvaraj4797]

Video code not clear

[@CamInstructor]

Make sure you are streaming in a high resolution, sometimes youtube automatically switches to something low if your connection is dicey. Bottom corner of the video, click the gear, in Quality select 1080p for best resolution.

Can you explain, please "BRANCHES AND LOOPS" OBJECTIVE: Enable participants to plan, execute and simulate CNC programs in 3 axes (milling machines and machining centers) with ISO / DIN structured language and programming. TARGET AUDIENCE: Professionals with basic CNC knowledge related to the machining area (CNC operators and programmers). . PRE REQUIREMENTS: Take a CNC Basic Milling course PROGRAM: Trigonometry Review Defining the variables Types of arithmetic functions Replacement Addition, Subtraction, Division, Multiplication Sine function, cosine function, tangent function Using conditional functions IF, GO TO, DO, WHILE EQ = equal NE = Different GT = Greater than LT = Less than GE = Greater than or equal LE = Less than or equal Simulation and practice exercises in a machining center (conical grooves, half spheres, corners of radius parts, ellipses, etc.) Can you explain, please "BRANCHES AND LOOPS" IF [ CONDITION IS TRUE ] GOTOn IF [condition is true] GOTOn for example, IF [#7 LT 0] GOTO65 If the value of variable #7 is less than 0, branch to block N65 ... ... If the above condition is true, bypass this section up to N65 ... N65 ... Target block of the IF conditional statement IF [ condition is true ] THEN [ argument ] Example 2 - Macro control with the IF-THEN structure #100 = #4006 Check current units (English G20 or Metric G21) IF[#100 EQ 20.0] THEN #100 = 0.1 Clearance above work is 0.1 inch for G20 IF[#100 EQ 21.0] THEN #100 = 2.0 Clearance above work is 2 mm for G21 ... < ... Macro program continues normally … > Using the IF-THEN method makes the pro gram shorter by one half and is eas ier to in ter pret. WHILE Loop Structure WHILE [condition] DOn WHILE [... Condition 1 is true ...] DO1 ... ... END1 Start of WHILE loop 1 End of WHILE loop 1 Double Level Loop WHILE [... Condition 1 is true ...] DO1 ... WHILE [... Condition 2 is true ...] DO2 ... ...

[@vital3d806]

I apologize, I am writing through a translator. Thank you for the video! please tell us about milling complex surfaces in a macro

[@CamInstructor]

Hope to do another Macro video soon. I'll keep your request in mind.

[@raulvictorangelessolano9509]

Estoy encantado con el profesionalismo que desarrolla en cada uno de sus tutoriales, sería tan amable en profundizar con temas de gran valor en programación de macros y programación CAM. "MASTERCAM"

[@CamInstructor]

Thanks. Always looking to add more videos on more topics, both in the beginner and advanced areas.

[@CNC-Guru]

Or you could use still G81 but different home positions :) in this case. This is too complex for the simple cycle. Macros should be used for complex milling. Great Tutorial, but you are jumping from simple stuff to hard and back.

[@raulvictorangelessolano9509]

Muy buen aporte, Excelente tutorial Deseo una certificación profesional en Mastercam Podría brindarme información.

[@CamInstructor]

Thank you. We offer certification testing through our online courses. You can see them here... caminstructor.com/mastercam-courses

[@BonaRasmey]

❤can you make a macro for hexagon hole say 14 dia.😊

[@agfisher007]

Subroutine and Macro for Z level milling would be nice..

[@endezoor]

You could do it with a parametric subroutine without using Macro. #1=2 (starting Z-level) #2=0 (finishing Z-level) G0 Z[#1+10] (safe height) WHILE [#1GT#2] DO1 #1=#1-1 (Ap) IF[#1LT#2]THEN #1=#2 (this eliminates the chances of making an undercut) G0 Xxx Yyy (starting pos.) G0 Z#1 *machining movements* G0 Z[#1+10] END1 G0 Z100 (safe pos. after milling) I hope this answer is good enough. If you want to do a macro, you would have a hard time to write the parametric code for the machining forms (such as rectangular, square, circle, free form, etc.). I think this one is the simpler solution.

[@agfisher007]

Thanx for the help....
