You can do this using and endmill tool definition, but you will not be able to put a radius on the top edge. https://www.dropbox.com/sh/smr3vo9js7u9a3x/AACA7vVrqZNCACCAvIa3auONa?dl=0

Attached is your tool & the DXF required to link it in Tool Manager. 26802.dxf 26802.tooldb

It says they partnered with Mastercam to develop toolpaths for this. http://www.mmsonline.com/blog/post/new-tooling-technologies-for-today-tomorrow

I use the Guhring RF 100 Speed end mills with much success. They are made specifically for Dynamic Style tool paths. The core is very thick for rigid cuts & the web is thinned for ramping and plunging. https://www.dropbox.com/sh/smr3vo9js7u9a3x/AACA7vVrqZNCACCAvIa3auONa?dl=0 RF 100 Speed_USA_8-2.pdf GUHRING RF100 SPEED ENDMILLS STAINLESS STEEL OVER 233HB.tooldb GUHRING RF100 SPEED ENDMILLS STAINLESS STEEL UNDER 233HB.tooldb

For 30 equal instances, your # of transforms should be 29. Your WCS needs to be Top. Your work offset should be set to "Manual" & 0. Posted just fine for me, you will need to add a clearance move between indexes though.

If you leave "force tool change" unchecked in the parent operation, the transform ops will not have tool changes. My post will force a tool change anytime I fill in a comment, so you should also check "remove comments" in the transform operation.

Thanks Colin! You are very generous.

I was looking at these too. They are only available for Fanuc & Mitsubishi controls. I wanted to package them with 2 brand new Okuma MB-66 verticals we are having quoted. (among other machines) Okuma will only use their own motors & encoders for DDRTs, so the Tsudakoma & Nikken units will not work. I have an RFEQ with OCJ, to see what can be done.

Hello, My name is Orvie John Smith. (it is not short for anything) I am 41 years old & live in Milwaukee WI. I am married to Katherine Smith & we have 6 beautiful daughters. Haylie(10), Ashleigh(9), Mollie(8), Natalie(6), Emily(5), & Tiffany(5). Yes, I mix up their names all the time. I work for Toshiba America Energy Systems. I started out as a Cutter Grinder making custom carbide tools for the automotive industry. I went on to mold making in the plastic injection mold industry. About a year and a half ago, I bought my own 5-axis seat of Mastercam to help support all of my beautiful ladies. Things are going well at work & at home. I love what I do, & I love teaching the new guys too. I am not certain how a space pilot pro is going to benefit my work, but I've read many great things about them & I'd love to find out the answer for myself.

I know Jody Romanowski. She has a business, "Hummingbird Integration". She is in fact a Cimco Reseller and more.

http://www.victornet.com/subdepartments/Acme-Taps/1320.html I would think a custom tap is the only way.

I I have never tried it any other way. This example including (comments) was given to me by Mr. Robson. I don't make it a point to quesiton him much. He has taught me so much about these controls. I like to pass along what I have learned whenever I can. We are currently having a few Mill-Turns quoted for the next fiscal year. Among the quotes were DMG-Mori & Doosan. I asked them if the Fanuc controls were capable of HSSV & they both assured me that this option was available. I told them that if they didn't have it, it would be a deal breaker. We use this feature on many projects.

It is available on both if the control is Fanuc. I cannot speak for the Siemens control.

Okuma's HSSV (turning) is standard on all their lathes and works very well. It is programmable too. I have a misc integer for turning it on. The VSST (threading) is standard for oil country lathes but is an option for most. The nice part about VSST, is you can change the rpm in the program on the fly.

I had this issue with 3 brand new machines, OSP300. Check these parameters & make sure there is some value for compensation deviation. We received our machines with zero tolerance as the setting. I have seen this many times with Fanuc arc tolerance settings also.

Your clearance plane is inside the part.

You can also use the MPLMASTER_THREADC post. You can create geometry for the exact lead out that you are looking for.

I had this issue with rotary limits. I had to set the Multi-turn parameter to ineffective. To avoid the directional codes (M15/M16), I set my rotary parameter to shortest direction. Shortest direction for rotation direction ( not M15 M16) NC Optional Parameter Bit No 69 Bit 0 4th-Axis to 1 Bit 1 5th-Axis to 1 Bit 2 6th-Axis to 1 After reset or Power on the rotary axis will always use shortest connection between 2 positions with M15 and M16 we can control CW or CCW. Short cut by M-Code M403 : 4th-axis M404 : 5th-axis M405 : 6th-axis If you issue M15 (M115) or M16(M116) in program this becomes direction command not shortest path If you change work coordinates machine will move not move in the shortest path Program Example: (****************************************) N1 (FOIL) M01 G30 P1 (TOOLCHANGE POSITION) M181 (CHIP CONVEYOR ON) M355 (CHIP COOLANT ON) G111 T1 Q0 VTWOH[1]=-.3125 (TL COMP ON FOR TCPC) (T1 - H1 - D1) (5/8 BALL ENDMILL) (DIA .625" - CORNER RAD .3125) G00 G15 H1 G56 H1 M510 (CAS OFF) X-11.6083 Y-1.9062 Z5.9391 A101.2357 G169 H1 X-11.6083 Y-1.9062 Z5.9391 A101.2357 S5600 M03 G131 F8000.

You will need to turn on Polar Coordinate Interpolation.

I hear that ICAM has a post engine that does this well.

In-House has this function working properly in my Okuma Lathe posts.

I have had timing to feature requirements before too. I used to cut a custom thread on a 10' dia with a 4.0" lead. on a 5 meter VTL with double start threads. Yes, 10 foot Dia.,(rock crusher parts). Anyway, I would scribe the O.D. With stock still on, calculate my "Q" (angular) shift & go. My requirements for this particular thread were to be within .001" every 90 degrees. I'm just letting you know that you can thread this very accurately & faster than milling. HTH

You don't necessarily have to shift your start point for a multi-start thread. Sometimes clearances will not allow for this. You can use "Q" to shift the start angle. This works with canned threading & long code threading. (G32) So for a triple start thread you would use: G32 ............Q0. G32 ............Q120. G32 ............Q240. or; G76X_Z_I_K_D_F_A_P_Q_; I : Difference of radiuses at threads K : Height of thread crest (radius) D : Depth of the first cut (radius) A : Angle of the tool tip (angle of ridges) P : Method of cutting Q: Shift angle of thread cutting start angle Depending on your control, you may not be able to use decimal points for the "Q" value. Q120. could need to be Q120000 or similar.
