Greetings, RICH.

I have made everything that you have told.

Has updated масн3 to last version. Has made a disk with one crack (diam 140mm, length 9мм)
Now the following has turned out:
When I twist a spindle a hand, approximately 2 turns in second, an index signal blink and speed of 90-110 turns in a minute is shown. Truly.
When I include a spindle on low speed, approximately 2-3 turns in a second, the index bulb blinks non-uniformly, speed of 200-2000 turns is displayed minute....

In what there can be a problem?

Thanks.

Good afternoon, РИЧ.

Today has anew established МАСН3, last release.
Here that at me it has turned out.
When the spindle turns on the minimum frequency, the indicator shows 221-222 turns in a minute. Truly. (S200)
I increase speed S300 - the indicator shows 240.
Increasing speed to a maximum (S1100) the indicator shows 340-341 turn in a minute.
Real frequency of rotation about 3000 turns in a minute.

Why the such can be???

The indicator a signal index in the controler blinks truly (at frequency about 800 turns in a minute, the eye can't distinguish a blinking.

The second question.
How to carry out cutting of an end face with constant speed of cutting (I.e. when the cutter reaches the center of rotation of a detail (Х=0,0000) speed of rotation was maximum)?

Thanks for the help!

Good afternoon.

XML file I will throw off a bit later.

Prompt as the program for cutting with constant speed looks.
It is necessary for me to cut an end face.

For example.
Diameter external - 50мм. Spindle turns - 500 turns in a minute.
To the center of a detail spindle turns should increase smoothly to 3000 turns in a minute.

I немогу to find as it is written....

Thanks.

Good afternoon, РИЧ.

A few having worked for me it has turned out to make that масн3 displayed real speed of a spindle (I have added signal Timing).
Remains not clearly why set speed doesn't correspond displayed on the screen.
For example:
I set S200 = 400
S500 = 600
S1000 = 1045

Values has written not precisely, but they precisely don't coincide.
I did calibration of a spindle.

I don't know as to attach XML a file
