CNC Engraving Made Easy Using G47 - Part 1 - Haas Automation Tip of the Day 

Muchas gracias!

Atomkinder67 - Check out ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-lwujoXvgGzA.html Thanks for the comment. - Mark, Haas Tip-of-the-day

Dharmesh Pattani - If I am just engraving a part number on one part or fixture, I often just use a Spot Drill (don’t tell anyone). For production parts, a small (1/8”, 3mm) die sinking endmill (runner cutter) with a .03” (,75mm) radius lasts really well. For cosmetic engraving (molds, golf putters), Single Lip Engraving cutters, with small “tip-offs” (flat at end) are often used. Tools with large radius on the tip, and blunt cutter angles, last longer. Pointy tools with sharper angles (like 15° included) tend to give better looking engraving, but the tools don’t last as long. Companies like Harvey Tool have a wide line of engraving cutters. Use lots of coolant on brass and aluminum. On steels, I’ll often just use a dab of tapping fluid on the part (no coolant). Run the highest RPM you can, and keep your feedrates low (.0005” Fz per tooth starting). - Mark, Haas Tip-of-the-day

To keep our tool down in the hole when peck drilling, we’ll use a G73 High Speed Peck cycle instead of our normal G83 Peck Drill cycle. Check out these two videos for more information, along with your Haas Manual. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-AM6nVgKjBQo.html and ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-YbbZJ7H0NUw.html . - Mark, Haas Tip of the day

Same problem sir, plz tell me solution?

Baldo - We can use a G101/G100 command to Mirror Image our Engraving, or any code really. Take a look at G101 in the Haas manual, which you can download from www.haascnc.com for more information. We will place a G101 X0. (Mirror On, about X-Axis X0) before our engraving, and place a G100 (Mirror Off) after our G47 engraving is done. Run things in Graphic Mode first to make sure it looks the way you’d like. - Mark, Haas Tip-of-the-day

+Barry Young Turn off Settings 74 9xxx PROGS TRACE and 75 9xxx PROGS SINGLE BLK, and you’ll be able to run these G47 engraving cycles on your simulator. By the way, my first program ever was a G47 engraving - “Mark was here” - on an aluminum skateboard deck two decades ago. Long story, good memories. Hope this helps! -Mark, from Haas' Tips of the Day

This is specific to a Haas machine as you probably already know. Have a wonderful day

We can engrave a diameter symbol, with a G47, by engraving a lower case “o”, and then engraving a forward slash “/” over it. Aside from this, we would need to use a CAM System. - Mark, Haas Tip-of-the-day. (DIAM SYM) G47 P0 (o) X0 Y0 J0.15 E5. F30. G47 P0 (/) X0.005 Y-0.02 J0.15 E5. F30.

This is a haas specific function.

Qusin111 - Sure, it’s pretty easy to mirror the engraved text. We’ll preface the engraving code with a G101 X (or Y), this turns on Mirroring. We turn off Mirroring when done with a G100. Check out G101 in your Haas Mill Manual. Thanks for the comment. - Mark, Haas Tip-of-the-day

Wally Cutler Mastercam is very easy to program

Pedro - Try turning Off Settings 74 and 75 on your simulator, this should fix your 257 alarm.

Steve - I cheated! I knew where the perfect spot was, because I had the CAD drawing. Check out 01:12 in the video, we show that our engraving starts in the bottom left corner of that first letter, even if it is at an angle. If I had to do this manually, I would Handle Jog the engraving tool above the part and note the XY location in the current Work Offset, and use that as my starting XY. It would probably still need some manual adjustments. Thanks for the comment. - Mark, Haas Tip-of-the-day

Wally Cutler - For engraving along an arc, we’ll need to make use of a CAM system. There are quite a few free CAM systems online now, that can create this code for us, that can easily be pulled into the control. - Mark, Haas Tip-of-the-day

Yes, you can engrave as fast as the tool can handle while still achieving a desirable finish. 40-120 ipm is perfectly normal.

in doing so you'd be sacrificing tool life would'nt you? if your engraving many parts this high speed will cause wear faster? or is it all the same because its the same material removal? thanks so much!

Cole - Speeds and feeds are very tool, material, and depth-of-cut specific. I think that the best looking engraving is done with tipped-off single-lip engraving cutters, but you have to go slower with these, about .001” per revolution or less on steel. Engraving cutters with radius on them (die sinking end mills) can feed faster and they last longer, but the engraving is rounded. Check out the Speeds and Feeds recommendations for these Harvey Tool cutters: www.harveytool.com/secure/Content/Documents/SF_25200.pdf. You can also see different engraving cutters on their site, www.harveytool.com/cat/Engraving-Cutters/Specialty-Profiles/Browse-Our-Products_195.aspx. I hope this helps get you started. - Mark, Haas Tip-of-the-day.

thanks for taking the time to reply!!

+Ralph Leonard If you're cutting the part in the machine, you can cut it : ) That depends on your tool. You can cut Stone, like granite or marble, but you need the right tool for the job. Some tools can engrave hardened steels.

+Kevin Rich Looks like a 'Die Sinker End Mill'. I usually use these as they are quite strong compared to a small ball nose endmill.

robpleasphoto ya want to know as well!

I guess 1 mm ballnose

Hi Denis, can you send us a private message with your machine's serial number. This could be caused by an older version of the software.

If you are a tech geek like me, this man is irresistible. Besides, I smile every time I hear his last name.
