how to measure axial straightness of bore tube or barrel
Feb 19, 2016 · But since the barrel may be bent (bore line not running true with the OD of the barrel, better to use a gauge rod in the muzzle bore, indicator off the muzzle bore to center the muzzle end of the barrel bore in the chuck using a spider as well, then cross side locked to the drive gear with the indicator mounted to in and indicator tip in the BEMIS-SC Small Caliber (5.56mm .45 Cal) Bore Erosion 11431 Willows Road NE Suite 100 Redmond, WA 98052 Phone (425) 885-0607 Fax (425) 885-0802 laser-ndt BEMIS-SC Small Caliber (5.56mm .45 Cal) Bore Erosion Measurement and Inspection System --BEMIS-SC Features-- _ - High Resolution laser-based inspection system for assessment of gun barrel condition Automated inspection process removes operator
Bore angle (pitch and yaw) can be measured by taking 2-axis target measurements at two points along a bore, typically at the very front and rear. By pulling the target through bores, the system is capable of recording a detailed pipe ID straightness measurement and tube ID straightness measurement. DOWNLOAD L-706 BROCHURE Bore Straightness Gauge - Pacific Tool and GaugeBore Straightness Gauge at Pacific Tool and Gauge. Gunsmithing Tools / Jigs & Fixtures > Precision Bore & Chamber Check Gauges > Bore Straightness Gauge Defense Technical Information Center Compilation Part Barrel straightness is defined by specifying the path of the barrel's symmetry axis. This can be determined, for example, by measuring the location of a bore-centered target as it moves down the tube. It is common practice to reference the bore centerline to either a line drawn
The measurement of axial motion of the projectile along the gun barrel against time is one of the important methods to study the work-doing ability of propellant powders. The interaction between gun bore and projectile is interesting to many ballistician and designers. The velocity of the projectile changes from zero to several thousand meters per second, so it is difficult to observe the L-706 Bore Laser System Bafco ReliabilityHamar Lasers L-706 Bore Laser Alignment System is highly accurate and unparalleled for ease of use.It can handle a wide range of bore alignment and straightness applications. Even extremely difficult bore alignment jobs, such as spherical bearings, can be done easily. Projectile balloting attributable to gun tube curvatureA smooth gun barrel that has a total length of 3840 mm was adopted and modeled. The measured vertical and lateral centerline variations along the down-bore distance from the rear face of the tube are shown in Fig. 2(a) and (b), respectively. It appears that the barrel had a slightly upward displacement between the 700 mm and 1300 mm
To gauge axis straightness effectively, MMC is commonly called out. To ensure that a part or feature is axially straight, a cylinder gauge is used to determine if the part fits in its total envelope at MMC. This is both a control of the diameter and of the axial straightness.
