Hi,
Got a problem with tool radius compensation for arcs.
The situation is the following:
1. The file in attachement (tried other samples with arcs, changed arc definition from XYIJ to XYR - nothing changes)
2. Define any non-null radius correction for the tool 1 in the settings of the DDSCV (when the correction is 0 all works ok). Both positive/negative - it doesn't matter.
3. Start the programm.
As soon as the controller reaches the first arc it stops. The execution could be stopped with stop button, so it's not a complete hang up. Controller simply stays on this command does nothing (waited at least 5 minutes - no continuation).

Tried with both 91 and 92 builds for the DDSCV2.1. Tried both hardware and software arc alghorithms. All steps per mm for all axes are equal. Re-flashed with default settings and changed only steps per mm and entered radius correction - nothing works.

The height correction works, btw.

(TOOL 1 - DIA 4.)

Sorry, due to the underlying mechanism, this problem cannot be solved on ddcsv. But on the DDHM controller we have redesigned the path generation mechanism and it looks good at the moment. The DDHM controller is currently undergoing translation work, and I think the English version should be available soon.

ytliu,
Has this issue been resolved in a current release of software? If yes....will it work in the DDCSV1.1?

Thank you,
RobT

OK, understood. Thanks for the answer. I can hope to fix this problem in the future?

Hi,alexwalex!
We already know the reason why the tool path with arc command under the DDCSV system has a radius compensation problem. In our new controller, we solved this problem by redesigning the tool path parse engine. However, due to the heavy workload of porting the new engine to the DDCSV system, I am very sorry that this may take a long time.

Hi, alexwalex!
I am very sorry, due to the loss of precision caused by the internal data conversion of the DDCVS system, the system has serious problems with the radius compensation support. It is recommended that you directly generate the compensated program through post-processing.

Hi, ytliu !
Got a problem with tool radius compensation:
If i define any nonzero value for the tool 1 radius in the settings of the DDSCV (parameter 284) - this and similar programm not work.

Still hangs in my case. What correction have you entered for the tool in controller settings?

I run your programm with parameter (284) D1=0 - it works.
Then i set D1=3 (for endmill diameter 6mm) - controller hangs.
Then i replaced in strings 8,31,52,73,94,115,136,157,178 value X to X-20 and controller works correctly with parameter D1=3.

Radius correction for arcs stops the execution of the programm
