An intermediate stop in 0i-F single-direction positioning explains how G60 preserves the final approach direction. One-axis calculations show additional travel, why an endpoint bounding box misses overrun, and the difference between one-shot and modal configuration.
Read article →The 0i-D optional chamfering and corner R chapter distinguishes chamfer setback, connecting-arc radius and an arc command’s own R. Original geometry for 90° and 60° corners tests whether a short edge can accommodate the specified fillet.
Read article →Using the 0i-D machining-center manual, calculations around a nonzero scaling center and an internal circular contour distinguish workpiece geometry, tool compensation and peck depth. Enlarging dimensions does not mean multiplying every value by two.
Read article →The 0i-D machining-center manual explains how 11600#5 AX1 handles omitted axes after rotation. An original 90-degree example compares endpoints for a Y-only command and an explicit XY command.
Read article →Using the 0i-F descriptions manual, point coordinates and signed triangle area explain single- and dual-axis mirroring. Geometric reflection, arc-direction handling and physical spindle rotation remain distinct to avoid reversing the program twice.
Read article →The cutter compensation C chapter of the 16i/18i-MB manual distinguishes geometric inaccessibility, compensation data and path-reversal checks. An internal-fillet example explains why reducing the offset value is not a valid way to clear an alarm.
Read article →A motion-free variable trace based on the 0i-D common operator’s manual compares G65 with M98. It explains argument A mapping to #1, restoration of local-variable levels, and why common variables are not isolated by those levels.
Read article →For a G01 linear model on a 0i-F machining center, inverse-time feed formulas calculate time and speed before and after segmentation. The article distinguishes G93 F from feed per minute and recalculates F to preserve ideal speed.
Read article →The 0i-D manual distinguishes the cylinder radius, rotary-axis angle and developed-surface arc radius in G07.1. An arc-length calculation explains dimensional errors, followed by key restrictions on mode transitions.
Read article →The original 15i/150i-MB manual distinguishes circular tangential feed from spatial-path feed. Calculations for the same hypothetical geometry show the two velocity components and why HTG semantics must be checked.
