The design of a coiled tubing cutter for use in subsea oil drilling applications
A cutting device has been developed which can be used in conjunction with Schlumberger's SenTree product line to insure proper disconnect of an offshore system from a subsea wellhead during the testing of the well. Design requirements for the device were established by the requirements of the …

Design and evaluation of an abrasive saw kickback machine
… saw kickback are often fatal. However, only woodcutting saws have regulations and assessment methodologies for kickback. These regulations do not apply to metal and masonry saws, as the cutting mechanism and dominant kick-back mode are different from those of woodcutting saws. In this work, the …

Characterising the dynamic response of ultrasonic cutting devices
… multiple-component systems used in ultrasonic cutting of food products are also investigated. Commonly, the design approach for ultrasonic systems neglects to account for the mutual effects of physically-coupled components in the system vibration. The design of systems also neglects the …

Theoretical investigation of kickback in diamond chainsaw and circular cut-off saw
… as an abrupt motion of the guide bar or cutting blade towards the operator. Despite the fact that early studies of this extremely dangerous phenomenon date back to the previous century, most of the available literature is limited to wood cutting chainsaws that are chip-forming, while …

Experimental and finite element modelling of ultrasonic cutting of food
In recent years ultrasonic cutting has become an established technology in a variety of industries including the food processing industry to cut a variety of materials. An ultrasonic cutting system consists of a generator, transducer and either a single or multiple blade cutting devices tuned to a …

Development of a hybrid process for manufacturing surgical-grade knife blade cutting edges from bulk metallic glass
… that can be achieved in single crystal diamond blades, but material and processing costs are high. Bulk metallic glass (BMG) has the potential to be an economically-viable material of similar performance for use in precision surgical knives. To this end, a novel hybrid manufacturing process …

Harvesting machinery technologies for precision and sustainable sugarcane production
… on sugarcane cut quality of four base-cutter blade designs: conventional straight blade, 30° angled blade, serrated blade, and straight blade with laser cladding on its underside. Stem damage and root system damage were considered as cut quality indicators. Percentage of undamaged stalks from …
