5 - Axis Explanation Needed

Edit
I am seeking a good understanding of 5 axis machining on a vertical mill. X, Y I believe are the table, Z is the spindle travel thats three. What would be 4 and 5?
a rotary table? Please Help me to understand this.
Thank You,
Robert

Robert,

I don't know if you're still needing an answer, but I might as well reply just in case someone else needs the info. On a vertical mill, you usually have the three "standard" axes (or "degrees of freedom"); that is, the bed can move in the three basic dimensions: left and right (X), forwards and backwards (Y), up and down (Z). For more complex operations, the mill may also have a head with the capacity to rotate about one or more axes. This would account for dimensions 4 and 5.

Hope someone finds this useful.

Cheers,
Andy.

X,Y,Z give you 3 cartesian axes. The other two are (usually?) are rotaries. Either the cutting head can have the rotary motion, or the rotry stages can be mounted on the X-Y platform.
Anyway, the two rotaries are at right angles, and the result is that the cutter angle w/r the blank is programmable.
