TL;DR: In this paper, a tool for blind holes or stepped bores is described, which has pivotable adjustable honing sticks and an anti-wear layer between the adjustable stick and guide strips.
Abstract: of EP0219825In the honing process, which is suitable in particular for blind holes or stepped bores, a honing tool (11) is moved into the bore (40) with retracted, that is non-expanded, honing layers, is expanded to the finished size in or behind the bore and performs its working stroke during the return stroke (direction 39). Chip removal takes place in a cutting zone (33) and the calibration to the finished size takes place in the finishing zone (34). The tool has pivotably arranged honing sticks. In a variant, guide strips firmly arranged between the adjustable honing sticks and having an anti-wear layer can be provided. Provision is also made to work with oscillating short strokes to machine the bottom area of a blind hole.

TL;DR: In this paper, two different designs of the magnetorheological honing tool are designed with the same parameters based on finite element (FE) analysis using Ansoft Maxwell, which results in more magnitude and uniformity of magnetic flux density in the working gap for the improved design of the tool.
Abstract: The magnetorheological honing (MRH) tool is an advanced finishing tool which is designed and developed to superfinish internal cylindrical surfaces. It uses magnetorheological polishing fluid consisting of carbonyl iron particles and cutting-edge silicon carbide abrasives in viscous fluid medium. The MRH tool with retained polishing fluid is rotated and reciprocated inside a cylindrical workpiece within the gap between the outer surface of the MRH tool and the inner surface of the cylindrical workpiece called the working gap. Due to the relative motion between abrasives (gripped by carbonyl iron particles chains) and the workpiece’s inner surface, finishing action takes place over the inner surface of the cylindrical workpiece. In this paper, two different designs of the MRH tool are designed with the same parameters based on finite element (FE) analysis using Ansoft Maxwell. The FE analysis results in more magnitude and uniformity of magnetic flux density in the working gap for the improved design of the MRH tool. Due to this effect, the abrasives are more strongly held with uniform strength which results in comparatively significant uniform finishing of the internal surface of the cylindrical workpiece. After confirmation of higher and uniform magnetic flux density on the improved MRH tool surface from FE analysis, two designs of the MRH tool are then fabricated with the same dimensions as taken in magnetic simulation. Experimentations have been performed with the fabricated finishing tools over the inner surface of cylindrical ferromagnetic workpiece of mild steel. The MRH tool with improved design results in uniform and more reduction in value of surface roughness with the same finishing time and process parameters as compared to the first proposed design. This confirms the enhancement in the finishing capability and better usefulness of the improved design of the MRH tool.

TL;DR: In this paper, the deformation in roundness of a real cylinder head is prevented by roundness honing of a cylinder bore employing a head model, and the head model is removed after the drilling of all cylinders 2A-2D and clamped thereon through the head bolt 9.
Abstract: PURPOSE:To prevent the deformation in roundness when an real cylinder head is mounted by roundness honing of a cylinder bore employing a head model. CONSTITUTION:After the boring of cylinders 2A-2D, a head model 3 is clamped securely on the top of a cylinder block 1 through a head bolt 9. Under such a condition, honing is inserted through holes 6A-6D of the head nodel 3 to hone to cylinder bore. After complete honing of all cylinders 2A-2D, the head model 3 is removed and instead a real cylinder head is likewise securely clamped thereon through the head bolt 9. This can positively prevent the deformation in roundness when the real cylinder is mounted.
