41. Ultimately, the effect of mandrel wrapping on optical measurements depends on the propagating mode power distribution. 42. The practical effect of mandrel wrapping is to attenuate optical power propagating in the highest order modes. 43. The mandrel diameter and number of turns are chosen to eliminate certain modes in a reproducible way. 44. Most cordwood saws consist of a frame, blade, mandrel , cradle, and power source. 45. The mandrel is a shaft and set of bearings that support and transfer power to the blade. 46. This method uses basic mechanical principles of deformation to achieve expansion of a non-tapered mandrel . 47. Following the formation of the container, the mandrel is used to fill the container with liquid. 48. A mandrel is used in many of the types to prevent buckling or wrinkling in the workpiece. 49. A tapered mandrel is set inside and a short distance from the start of the central void. 50. In production of a product where the bend is not critical a plug mandrel can be used.
