The 0i-F polygon-turning model separates side count from flatness. Original ellipse-semiaxis and tangent-deviation calculations explain the limits of approximately straight sides, without equating a hexagonal outline with exact planar surfaces.
Read article →The 30i-B continuous-circle groove-cutting rules relate groove advance to pitch per revolution. Two tool diameters and circular-acceleration limits show why commanded F cannot be equated directly with progress along the groove.
Read article →The 0i-F lathe manual’s G32 multi-start threading rules relate a three-start thread’s lead to its 120° phases and integer Q values. The article separates first-block rules for continuous threading from independent cuts and explains why ordinary G76 Q is not a phase angle.
Read article →The 16i/18i-MB dynamic fixture offset definition supports a planar single-table model. Calculating an eccentric workpiece origin at 90° explains how a correct reference-angle setup can still produce position error after the table rotates.
Read article →Official FANUC 30i/31i-A5 material distinguishes TCP, Tool Posture Control and Smooth TCP. Geometry of a reference point on the tool axis shows how angular differences grow with distance, without equating the tool-tip path with the path of the entire tool.
Read article →For 30i/31i/32i-B machining centers with a nonzero fixed denominator, original, doubled and normalized IJK values give different compensation displacements despite identical direction. The article also checks zero components, activation mode and vector retention during arcs.
Read article →The G10 parameter-input modes differ explicitly between 0i-C and 0i-D. Using the original 0i-D common manual and generation-differences appendix, this article explains the data meanings of L, N and R and an offline review method for older maintenance programs.
Read article →The 0i-F parameter manual separates shared external workpiece offset from individual coordinate offsets. A translation model and three-station example distinguish common shifts from a single-station error without treating measurements alone as proof of the cause.
Read article →The 16i/18i-MB macro rules distinguish undefined variables, numeric zero, direct assignment and arithmetic conversion. An original position example and condition table show why omission must be detected before calculation, rather than using a nonzero test for argument presence.
Read article →The 0i-F machining-center figure-copying rules explain why the nth transformation uses n−1. Original linear and three-way rotational arrays calculate first and last positions, with the first subprogram block and inter-contour connections treated as separate constraints.
