Face Milling - Fly Cutting
Surface Finish, and "Blend" Not Acceptable?
Are you getting a step when you face mill?
A few of the many causes,
1. Column not square to table (base not level)
2. Column not parallel to table (column "pointing" left / right)
3. Head not square to Column (gibs loose)
4. Spindle not square to table (gibs loose)
Do you spend extra time going over surfaces trying to get a GOOD FINISH and get them FLAT?
First SIDE to SIDE, UP and DOWN, and even ONE DIRECTION ONLY!
As you can see if you have loose gibs in your head and your column is leaning, your spindle can still be LEVEL and SQUARE to "EARTH". However, when you traverse the head up or down, the spindle end gets closer or farther away from the PERPENDICULAR part. So you indicate the part to the travel. OK, then all you have to worry about is that the "front" and "back" DO NOT need to be PARALLEL, and if you rotate the part you get a TRAPEZOID or PARALLELOGRAM depending if you indicate the part or not. After you indicate the part you now get a step when you mill side to side, so you mill bottom to top. This doesn't even consider that the spindle may be "pointing" left or right causing "heel" cuts, so you can get a step going up and down. How about only going one direction to additionally compensate for tool "pressure".
THESE ALIGNMENT CONDITIONS AND MORE - ONLY COST YOU TIME AND MONEY!
Now it's time to think about pocket milling. All these parameters are involved, plus the backlash (reversal error), and Linear Positioning error.
During normal operation, the running clearances of any machine will "open-up". Vibration, temperature variations, concrete settling and even "crashes" can add to the problem. If your machine has not been inspected and adjusted for some time the possibility of irreversible, damage exists due to uneven wear.
If you can't or won't be satisfied all this additional work to get a good surface finish, not to mention the front to back (top to bottom) PARALLELISM then you need to think about the LEVEL, SQUARENESS, PARALLELISM, STRAIGHTNESS, and FLATNESS of your machines.
We have years of experience in eliminating these detrimental conditions.
