COMPENSATING FOR W IN MASTER CAM

[dcutler35]

I am using a generic 4 axis mill post for fanuc in inches and I just started programing for a horizontal boring mill it has x axis table movement y axis spindle up and down z axis spindle in and out also it has a rotary table with b axis and the w axis movex the spindle column. Does master cam make a post that will take w into consideration when writing a program ?I have been programming for VMC for a long time now and use the touch off method to set my tools so I am now exploring what it takes to run an hbm any help would be greatly appreciated even a suggestion to a book or reference would be helpful. I am confident I will learn how to make it work I would just like to learn it faster and with as less problems as possible

Wouldn't this have been a question for your reseller or MasterCam directly?

You have to get a custom post from your dealer. it doe's not ship with a HMC with "W" support. Sorry

true txcncman and I have been tryign to get in touch with him he just emailed me a bit ago and said no prob on the post he said how you control w is depends on how you use it and that got me scratching my head oh by the way I did what you said and I realize now how to set my tools and my z offset properly to run my programs thanks for the help txcncman I was telling my boss and he thinks he might want you to come and help us out I will keep you posted.

Glad it helped. Trying to explain with typewritten words does not substitute for seeing something demonstrated in person.

Amen to that but that last post reguarding where to compensate for w is what helped get it clearer in my head and doing what you said really made me realize how and where compensation was done

[PRINT_FX]

your post should generate a G173 W value...
you can set that up on misc values, I never extend the spindle to touch tools but to touch the part I have to use the G173 in order to compensate the w value

I just got off the phone with my reseller he is going to give me a post whithout w moves and then I will add in the m functions and I am still trying to determine what actions I want to to in w mill drill bore and what to do in z ? the sindle is attached to a moving colmn (w) and it is big any ideas
