Abstract: - Efficiency of industrial production lines is crucial as it results in an improved production and utilization of available resources. Factors contributing to production line efficiency are manpower utilization and machine efficiency. Measuring the machine efficiency and man power utilization should be on-line, accurate and truthful.

2. Continuous dressing, which is beneficial in large-quantity production in materials that are difficult to machine or grind.The continuous dressing enables the grinding wheel to stay sharp constantly, while maintaining intricate forms. Continuous-dress creep-feed grinding uses an overhead diamond dressing roll to plunge dress continuously during the grinding cycle.

Calculating Mechanical Advantage and Efficiency of Simple Machines In general, the IMA = the resistance force, F r, divided by the effort force, F e . IMA also equals the distance over which the effort is applied, d e, divided by the distance the load travels, d r .

There are many factors influencing the grinding efficiency of ball making machine. As for one ball mill grinder, when processing one mineral, the influencing factors of grinding efficiency include property of grinding media, matching of grinding media, filling ratio of grinding media, ratio of grinding balls to materials, grinding density and feeding granularity.

Before getting into the four categories that influence grinding efficiency, it's important to know how the grinding process works. When you're using a grinding machine, three interactions are happening at the same time: cutting, plowing and sliding. What you're creating determines the primary interaction occurring.

Machine Efficiency Machine efficiency can be measured in terms of energy efficiency or the productive results of equipment. The latter approach uses the value of outputs and cost of inputs. In a month, a drilling machine takes inputs such as labor, electricity, materials and depreciation on the machine itself that cost 50,000 dollars.

(xiv) Loading and unloading time is 10% of machine time, (xv) You can make suitable as­sumptions if necessary, for the purpose of your computation. Notes: (1) Total working hours per annum are 200 x 12 = 2,400. (2) Loading and unloading time is 10% of machine time. (3) Effective working hours are 2,160 hours (2,400 – 10% of 2,400).

At present, the complex components are mainly ground by virtue of manual operation and multi-axis CNC machine tools. Two typical examples of grinding turbine blade and wind blade are shown in Fig. 1.Because of the time- and labor- consuming as well as the harsh operating environment experienced by manual grinding, the multi-axis CNC grinding has …

Just so, how is grinding wheel consumption calculated? 1. Wheel Speed Average rpm = sfpm / (π/12 × DH) Wheel diameter at half of wheel life (DH) (in inches) = Start Dia. – Wheel Wear per Grind Cycle = Continuous Dress Amount per Revolution of the Wheel (CD) × rpm × Wheel Travel / Table Speed.

Efficiency. Efficiency is the ratio of the work performed by a machine or in a process to the total energy expended or heat consumed. Efficiency refers to how close we can get to a particular outcome of the given input with as much less wastage as possible.

Efficiency of Induction Motor- The analogous circuit of an induction motor can be utilized to assess the machine's losses and efficiency. The efficiency of induction motor is determined in the same way as it is for any other device. Motor losses have a direct impact on the cost of operation and, indirectly, on the motor rating.
