Abstract:

The configuration of a tachogram of the machine sewing process is described using a polygonal curve. It is stated that the efficiency of a tachogram with its configuration established is determined using the following: values of machine parameters, the responsetime of an operator to visual signals and delays in the circuits of textile control, the drive set in action by the operator, the efficiency of reactions established in a tachogram, the number of machine working cycles, as well as the share of particular reactions of the tachogram in a general number of machine working cycles. It is also stated that the minimum number of machine working cycles for which a technological task can be carried out is characteristic for the particular configuration and parameters of the tachogram. The experimental results obtained were used for the programme control of a sewing machine drive in a machine - operator system.

Tags: sewing process tachogram, polygonal curve, sewing machine drive, operator response time.
