Grinding and Finishing

2013-10-14 · Grinding – Ex. 1-1 • You are grinding a steel, which has a specific grinding energy (u) of 35 W-s/mm3. • The grinding wheel rotates at 3600 rpm, has a diameter (D) of 150 mm, thickness (b) of 25 mm, and (c) 5 grains per mm2. The motor has a power of 2 kW. • The work piece moves (v) at 1.5 m/min. The chip thickness ratio (r) is 10.

Machining Processes

Grinding is no exception. So, while Makino machining centers are helping manufacturers cut cost and time by minimizing non-cut time, setup time and tool-changing time, new technologies that combine grinding and milling in one setup in one machine are also reducing part cycle times by as much as 75 percent. Better, faster, more cost-effective.

Calculate Cycle Time | Information, Training, current Best ...

Cycle Time calculation in a Continuous Process. Cycle time = Average time between completion of units. Example: Consider a manufacturing facility, which is producing 100 units of product per 40 hour week. The average throughput rate is 1 unit per 0.4 hours, which is one unit every 24 minutes. Therefore the cycle time is 24 minutes on average.

Production Time Calculator

Production Time Calculator. The production time for a manufacturing process is primarily determined from the cycle time, but must also account for the defect rate, machine uptime, and machines used. Using these parameters, the run quantity, run time, down time, total production time, and production rate (parts/hr) will be calculated.

Machining

Machining is a term used to describe a variety of material removal processes in which a cutting tool removes unwanted material from a workpiece to produce the desired shape. The workpiece is typically cut from a larger piece of stock, which is available in a variety of standard shapes, such as flat sheets, solid bars, hollow tubes, and shaped beams.
