...determine accuracy of hole drilling, both largely depending on drill diameter and whether centre drilling and bushing are used. The smaller the drill, the greater the accuracy. For 6–18 mm drill diameters, location varies from ±0.05 to ±0.2 mm, oversize from 0.075 to 0.15 mm. Surface finish is typically 1.5–5 µm Ra, but can be as low as 0.5 µm Ra. Milling Cutters...

...determining our climate. Recent studies suggest the coldest water in the Antarctic Circumpolar Current (ACC) is being pushed further southwards due to rising temperatures.The opening of the Drake Passage is believed to be around 35 million years ago but a shallow connection has been proposed long before this time. The ACC is the largest ocean current on our planet,...

...determined area. Patients are advised to speak to their GP to understand any modifications to their treatment plan. It is possible that tests will be rescheduled if the clinician thinks this is the safer option. Will the coronavirus outbreak delay and/or stop current cancer treatments? The healthcare support team will always weigh up the benefits and risks of modifying...

...cutting, and under ideal cutting conditions it is these drag lines which determine surface roughness. Dimensional control of flame cut sheet and plate is largely dependent on accuracy of profiling equipment and the thermal expansion of the material.
