The quotation rule mapping between the quotation formula and the request-characteristic variable as well as the product module is obtained based on the feedback amendatory coefficient,and the quotation method based on feedback amendment for multi-specification and small-batch mechanical production is realized.

An impedance control strategy based on firing-angle modification feedback is proposed,which compared with that based on impedance error modification feedback,avoids the firing-angle table search for each modification and speeds up the response of low-level control.
