Repeating OKUMA CNC Lathe program number of times

January 6, 2011, 2:00 pm by Eldar Gerfanov

If you want OKUMA Lathe to repeat program several times you can use a subprogram or a conditional GOTO statement.

On Many Okumas subprograms is an option you have to buy, so we have to use GOTO statement.

Code
O1 
CN=7 (NUMBER OF CYCLES TO REPEAT) 
CC=0 (CURRENT CYCLE)
N0
......
(part program)
......
CC=CC+1 
IF [ CC LT CN ] N0 
M2

Thats it 

This little code helps alot when using bar feeder and stuff like that.

 


Avoiding Chatter in corners of a pocket

January 3, 2011, 2:02 am by Eldar Gerfanov

If you are finishing a pocket with wall corners' radius close to the radius of a cutter. The tool tends to chatter, especially with longer tools and harder materials.

To avoid this you can do one of the following:

  • When programming. After roughing the pocket and before finishing. Create a simple drill cycle with finishing tool to remove extra material from the corner. This way when finisher goes to the tight corner, the chatter will virtually disappear.
  • Do the same with a drillbit. Before Roughing.

Here are few basic formulas with term explanations to get you going: 

Calculating Spindle Speed (RPM) Using Imperial Cutting Speed:

Code

RPM= 12 x SFM
3.14 x Diameter

Simplified imperial formula:

RPM= 3.8 x SFM
Diameter

Calculating Spindle Speed (RPM) using Metric Cutting Speed:

Code

RPM= 1000 x SMM
3.14 x Diameter

Simplified metric formula:

RPM= 318 x SMM
Diameter


Calculating Feed Rate :

Feed_Rate=RPM x N(teeth) x CL(chip load)
