Abstract

The limitation of specific power consumption in the woodworking enterprises is being constructed in accordance with the decomposition of the production process: certain operations and processes by type of products and some parts (units, shops, an enterprise in general). Accordingly, there are the operating specific power requirements for individual processes
and total specific power requirements for individual production processes. The aim of the paper was the approach of establishing of the operating rules of specific energy consumption to perform the cutting operations on cutting machines, which are used in the production of sawn timber for longitudinal edging of unsquared boards and slabs. The research of the energetic properties of the electric drive of a cutting machine are conducted in the direction in which the loss and useful energy consumption are determined through some loss rates and performance of the unit. In the study the analytical relationship between power consumption, specific power consumption and productivity of a mechanism of a cutting machine,
known as the energy characteristics, are obtained. The used method allows us to express the net load to the unit through productivity – an indicator, which practically reflects the results of the unit, site, department, etc. Planning of specific energy consumption for each standard size of assortments and production is solved more efficiently with the help of the power characteristics. The energy consumption characteristics of a cutting machine is linear, the nature of the specific energy consumption is non-linear. The basic technological factors and parameters of equipment and raw materials affecting the specific power consumption of the cutting machines are identified.
