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.

Close miking is a crucial technique for a majority of recording situations. Playing live in a bar, on stage singing or giving a speech, and even in the perfect acoustic environment of a world-class studio, close miking has it's place as one of the most effective means of faithfully capturing a sound source or instrument while keeping the signal as dry as possible.

Acoustic measurements have been conducted using a microphone array located in the front of the mill, at 1.36 m from it (Fig. 3 (a)). The array is composed of 64 1/4" GRAS 40 pH phase matched microphones (frequency range from 50 Hz to 10 kHz). Those microphones are mounted on a 2 m by 2 m perforated steel grid using plastic cable glands.

1. Use the right tool for the job. Grinding discs are consumables; the power tools shouldn't be. Be sure to use the appropriate grinder that can handle adequate amperage for the job at hand. If an application calls for between 8 and 10 amps of pressure, and you use a right-angle grinder rated for only 6 amps, you're in trouble from the start.

The intelligent grinding system included several vibration, temperature, and acoustic emission sensors and a microphone to monitor the dynamic status of machine during the grinding process and help to quality control. The wear of the diamond grinding wheel could be predicted immediately by analyzing the collected data in this system.

So another method for miking an instrument is to use a boom mic stand and place it over the performer's shoulder near their ear. Now you'll be recording precisely what they're hearing, so you know it's tolerable at least, if not absolutely fantastic. Freeform Monitoring. This is the real rule.

A Basic Understanding of Surfer Gridding Methods – Part 1. Surfer offers many different grid based maps, such as 2D contour maps and 3D surface maps. To create a grid based map, you must have a grid file. To create a grid file, Surfer takes randomly spaced XYZ data and uses it to create a regularly spaced grid file, composed of grid nodes.

In this study, a multi-sensor fusion method of vision and sound is used to monitor in-process grinding material removal rate (MRR). First, belt grinding experiments are conducted using different grinding parameters, and vision and sound signals are captured by industrial CCD cameras and an omnidirectional condenser microphone, respectively.
