Conclusions

  1. 1.

    One-way trimming is more effective for technological processes with σμξ < 1.35, two-way trimming with separated signal boundaries is optimal for 1.35 ≤μξ ≤ 2.4, and pulsating trimming (forτ=1) is optimal for σμξ > 2.4.

  2. 2.

    Graphs and relationships are provided for calculating two-way trimming parameters for initial processes with intervals of σμξ = 1.35–2.8 and\(\bar \mu {_\xi}\) = 0–0.34, which cover a sufficiently wide range of the possible values of σμξ and\(\bar \mu {_\xi}\) and are suitable for practical application in through-grinding of details.

  3. 3.

    A rising delay cycleτ reduces according to (5) the quality of two-way trimming of processes by means of an optimum pulse.
