On a CNC or automatic surface grinder when should the wheel advance (crossfeed) over the work, when the table is fully right or fully left. I would think it would be correct to advance the wheel when the table is left so as the table comes back to the right you are making a conventional cut as opposed to climb grinding.

I have my "new" Brown and Sharpe Techmaster in place and need to start using it, while using it over the next few weeks/months I need to correct the programming in the PLC. It was converted to an Allen Bradley SLC 500 plc from its original Modicon.

The programming in it is just enough to make it go back and forth and advance the wheel in incremental mode only. The other crossfeed settings do nothing and the crossfeed STOP button only causes the light to light and does not stop anything at all.

The first item on my list is does it crossfeed at the correct end of stroke?

Advance the cross feed at both ends of table travel.
