The 16i/18i-MB manual distinguishes one-block exact stop, modal exact stop and continuous cutting. An independent acceleration/deceleration model quantifies repeated stopping, while explaining why an in-position range does not mean zero contour error.
Read article →The 0i-D program-restart chapter distinguishes N sequence numbers from the executed block count, including pure macro statements and the FEED HOLD / RESET display boundary. An original table shows why copying a number is not enough to restart.
Read article →The dedicated 0i-D manual intervention and return function distinguishes return to an interruption point from replaying a manual path backward. Original geometry shows different swept regions with identical endpoints, alongside reset cancellation and distance-to-go limits.
Read article →The 0i-D system-variable chapter distinguishes the preceding-block modal state at the look-ahead processing position from the executing block. An original timeline explains differing #4001 and #4201 values without treating program-state reads as motion-complete signals.
Read article →The 0i-D polar endpoint definition and an original chord calculation show why G16 does not turn G01 into an arc. A comparison with Cartesian input and rotary-axis conversion in 0i-F lathe G12.1 distinguishes the two polar functions.
Read article →The 0i-F machining-center normal direction control chapter relates C-axis angular travel to arc length and speed. Distinguishing corner orientation from continuous arc following explains small-radius feed limits and configuration prerequisites.
Read article →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.
