Different feedrates in chain

[maestro]

Is there any way to change feedrates in different portions of a chained contour?

Using V7.2b.

[Kenneth Potter]

In your ops manager right click the Geometry Icon to bring up the chain manager.Inside the chain manageger right click the chain Icon connected to your tool path & select change at point.Endpoints will appear in the grafixs screen to your tool path geometry. Choose your point. A change at point option box appears. There you change your feed, c-comp,spindal speeds, ect.

is there any way to do same functions of

Optipath's Vericut(changing feedrates), in V8, without buying the first one.

rmsimoes,

?????? Do you mean, "Do I have to buy Mastercam Version 8", or "Do I have to buy Vericut?"

buy metcut . it does a better job . it works

with the limitations of your machine. and it works with what ever version of mastercam you have

my personal opion

might even be cheaper

Thanks Kenneth. I've been using Mastercam for about 1 year now. Love this forum. Learn a lot just by reading questions & answers. Lots of great info.

One quick tip. If you want to add more points to edit in your tool path.Just break up your geometry by using the many break options.

Main menu/Modify/break

Then rechain geometry & regenerate your tool path.

Then you can edit AT point.

Have you explored the HighFeed C-Hook in V7 or the function built-in to V8?

"The Highfeed C-Hook optimizes feed rates for 2.5 axis and 3 axis mill tool paths. It computes feed rates that reduce machining time without sacrificing accuracy. Instead of using the same feed rate for the entire part, a different feed rate is computed for each tool position based on the volume of material currently being removed resulting in a faster machining cycle and control over the machining forces."

[maestro]

I have looked at it a little, but have had a little trouble finding good instructions on how to use it. Could you point me in the right direction?

Go to www.mastercam.com, then to the support section. Download HFAPP_V8.doc. This is a pretty good guide.

The document Hfapp.doc was available for V7 and could possibly be found in the Chooks directory. Failing that, the Patches page for V8 on this site has the V8 equivalent available for download:

http://www.emastercam.com/info/patches/v8/index.html

Hfapp_v8.exe - (High Feed Applications Guide) - gives detailed information about using the High Feed Machining function in Mastercam Mill. Hfapp_v8.doc in MS-Word format extracts to Mcam8Chooks.
