(1) Determining parameter No. 2048
To determine parameter No. 2048, an adjustment must be made at low
feedrate. This example assumes a feedrate of F500 mm/min and a
radius of 10 mm. Adjust an optimum value at a low feedrate, and set it
in parameter No. 2048. The figure below shows the result of setting 30
in parameter No. 2048. Here, this value is set in parameter No. 2048.
(2) Determining parameter No. 2114
Parameter No. 2114 must be set after the adjustment of parameter No.
2048. About a half of the maximum cutting feedrate is used to
determine the value to be set in parameter No. 2114. In this example,
F2500 mm/min is used. By increasing the value in parameter No. 2114,
determine an optimum value that does not cause undercuts. Increasing
the value in parameter No. 2114 increases the actual acceleration
amount.
The following figure shows the result of the adjustment of parameter
No. 2114. Quadrant protrusions can be suppressed satisfactory.
