Feedrate Slows Down for No Reason During Machining

Had this problem occur on a machine where the customer was milling across a long part. During the machining process the feedrate slows down and speeds up constantly. After troubleshooting the feedrate problem I determined that the spindle speed was slowing down as well. When the spindle speed slows down the feedrate automatically comps to maintain the recommended rate of removal and changing with the spindle speed.

If the RS232 port does not work any more.

What if the RS232 port is bad or not working on your Fanuc control?

Recieved this from a Member of Machinetoolhelp.com for if you have a bad RS232 Port on a main board or some fanuc controls. Since most fanucs have two ports you can just swap the plug to the other port that is not being used and have a fully functional RS232 port. Then use a different channel for setting your RS232 settings. Wish I would have known this years ago or thought of it.

Fanuc Powermate F alarm 090 224 on machine power up.

A Fanuc Powermate F alarm 090 224 occurred on a customers machine at power up. Had tried to walk him through resetting the powermate home position several times but the original procedure would not work. The 090 and 224 alarm indicates a lost home position. However batteries were ok and they were replaced as a precaution. The problem was that it was impossible to reset the home position and it would not take. Fanuc Powermate drives often are stubborn from my experience when setting there home positions.

301 B axis communication error on fanuc control

301 B axis communication error came up on a fanuc controlled machine that had scales for the B- axis or rotation of table. After troubleshooting everything and getting down to that it had to be the scale. Ordered a new scale and tried it. Unfortunitly the same alarm occured. After looking into the parameters I was able to tell that someone had turned off the scale at one time because all the paramters had told me so except for one. Parameter 1815 bit 1, bit4, and bit 5 were all 1's.

Soft overtravel limit alarms when Zero returning alarms - 500 & 501(soft over travel)

All to often I get phone support calls for soft overtravel alarms on fanuc controls. The soft overtravel limit alarms typically occur after a power outage, hitting an overtravel, or crashing a machine. Many times it is an Alarm 500 nth Axis stroke limit + or 501 nth Axis stroke limit  on the newer fanuc controls 16/18/21.

Next tool code positions tool but does not change tool. Help!

We have a Mori Seiki GV-503 5AX with a Meldas M66 control. I want to position the magazine for the next tool. When I write the code shown below, the tool positions at the pot correctly but the tool in the spindle does not change at the next M6. The tool thats in the spindle goes to the tool change position but does not change and continues the program.

Spindle speed bogs down while cutting

I was working an Emag CNC machine the other day. The customer was having problems when they were boring into the part. The spindle would bog down during the cut. When viewing the Spindle actual RPM compared to the commanded spindle speed the actual would decrease to about 1200 from 3000rpm. To try to determine the problem I had a few things I checked first. The tool ins
