Как использовать таблицу определения подачи на зуб fz: 1. Определение индекса подачи (например, 181B, где „B“ – это индекс подачи). 2. Определение ближайшего диаметра фрезы по верхней строке таблицы и по шагу резьбы P или TPI. 3. Выбор строки с индексом подачи в первой колонке таблицы. 4. В ячейке на пересечении выбранных параметров будет значение подачи на зуб фрезы f . z
Поправка подачи при обработке резьбы за несколько проходов: 5. Если резьба обрабатывается за 2 прохода, указанные в таблице значения следует увеличивать на 30...40 %. 6. Если резьба обрабатывается за 3 прохода, указанные в таблице значения следует увеличивать на 55...65 %. 7. Если резьба обрабатывается за 4 прохода, указанные в таблице значения следует увеличивать на 80...90 %. Подача на зуб фрезы f , мм/зуб. (Пример: J2003.2X.7 фрезерование WMG M4.1 с индексом подачи A за 4 z Указанные значения рекомендуются в качестве начальных при обработке полного профиля прохода f = 0.017 × 1.80 = 0.031 мм/зуб). z резьбы за один проход.
