This CNC macro automates the process of measuring and storing the length offset for a specific cutting tool. It uses the machine's built-in probing functionality (G37) to contact a reference surface and automatically cal...

The `MEASURE_TOOL_LENGTH` macro takes a `TOOL_NUMBER` as input. It calculates the corresponding tool length offset register number (e.g., H101 for tool 1) by adding 100 to the tool number. It then moves the tool to a safe starting position. The core of the macro is the `G37 H[tool_length_offset_register]` command, which instructs the CNC machine to move downwards until it contacts a pre-defined reference surface (like a probe or a height gauge). Upon contact, the machine automatically measures the distance from the machine's reference plane to the tool tip and stores this value in the specified offset register. Finally, it prints a confirmation message. This simplifies tool setup and ensures accurate depth control for subsequent machining operations.

This subprogram automates the machining of a circular pocket on a CNC machine. It takes the pocket's radius, depth, and center coordinates as parameters. This is useful for creating features like mounting holes or recess...

The algorithm defines a parametric subprogram `CIRCULAR_POCKET` that accepts `RADIUS`, `DEPTH`, `CENTER_X`, and `CENTER_Y` as inputs. It first validates that the `RADIUS` is positive and `DEPTH` is negative, exiting with an error message if not. The subprogram then sets up the tool and spindle, moves to a safe Z-height above the pocket center. It iteratively plunges the tool into the material, machining the circular contour at each depth increment using G2/G3 commands. The `WHILE` loop continues until the desired `DEPTH` is reached. Finally, the tool is retracted to a safe Z-height, and the spindle is turned off. The use of a loop for depth control and parameterized inputs makes it adaptable to various pocket sizes and depths. The error checks prevent common machining errors.

The `ADAPTIVE_HSM_POCKET` program aims to optimize pocket machining using HSM principles. It takes pocket dimensions, tool diameter, and a target MRR as input. The algorithm first sets up the tool and spindle, then iteratively plunges the tool to increasing depths. At each depth, it calculates an adaptive `stepover_distance`. This calculation considers the `POCKET_WIDTH`, `TOOL_DIAMETER`, a range of `MIN_STEPOVER_ANGLE` to `MAX_STEPOVER_ANGLE`, and a `current_feed_rate` derived from the `MATERIAL_REMOVAL_RATE_TARGET`. The core idea is that at shallower engagement angles, the stepover should be smaller to avoid overloading the tool, while at deeper engagements (closer to 90 degrees), a larger stepover is permissible. The program then simulates a trochoidal milling path, where the tool moves in a series of overlapping arcs. The provided code simplifies the trochoidal path generation; a true implementation would involve complex geometric calculations for arc centers and radii. The `CALCULATE_FEED_RATE` and `CALCULATE_ADAPTIVE_STEPOVER` functions are placeholders for these complex calculations. This adaptive approach ensures efficient material removal and tool longevity.

This macro dynamically adjusts a tool's active offset (either length or radius) based on its current wear value. It reads the wear from a designated storage location and applies it to the tool's offset register. This all...

The `APPLY_WEAR_OFFSET` macro is designed to adjust tool offsets dynamically based on wear. It takes `TOOL_NUMBER` and `OFFSET_TYPE` ('L' for length, 'R' for radius) as input. It first determines the appropriate offset register (e.g., H101 for tool 1 length, D101 for tool 1 radius). It then calls a conceptual function `GET_WEAR_VALUE` to retrieve the current wear amount for that tool and offset type. For length offset, it conceptually uses `G43 H[offset_register] Z[current_wear_value]` to add the wear to the tool's length compensation. For radius offset, it conceptually uses `G41 D[offset_register] X[current_wear_value] Y[current_wear_value]` to apply the wear to the radius compensation. The actual implementation of applying wear dynamically varies significantly between CNC controllers; some might use specific commands for wear compensation or require the wear value to be incorporated directly into motion commands. The macro includes basic error handling for invalid `OFFSET_TYPE`. The primary benefit is maintaining accuracy as tools wear down.

This algorithm implements adaptive feed rate control for High-Speed Machining (HSM) contouring operations. It dynamically adjusts the feed rate based on real-time estimations of material removal rate (MRR) and tool load....

The algorithm `ADAPTIVE_HSM_CONTOUR` aims to optimize cutting parameters for HSM. It initializes with a tool and spindle speed, then iterates through contour segments. For each segment, it estimates the Material Removal Rate (MRR) based on cut width, depth, length, and spindle speed. It then simulates or reads the current tool load. Based on the tool load relative to a `TARGET_TOOL_LOAD_PERCENT` and `MAX_TOOL_LOAD_PERCENT`, the `current_feed_rate` is adjusted. If the tool load exceeds the maximum, the feed is significantly reduced to prevent breakage. If it's above the target, feed is slightly reduced; if below, it's increased. Spindle speed is also adjusted adaptively. The algorithm includes checks for critical tool load conditions and a simulated tool breakage event, halting the program if necessary. The feed rate is always clamped between `MIN_FEED_RATE` and `MAX_FEED_RATE`. This dynamic adjustment ensures efficient material removal while protecting the tool and workpiece.

This program demonstrates how to implement coordinate transformations for machining on rotated planes. It defines rotation matrices based on user-specified angles and applies these transformations to convert tool path po...

The `ROTATED_PLANE_MACHINING` program handles coordinate transformations for machining on arbitrary planes. It begins by calculating a combined 3D rotation matrix (`rotation_matrix`) based on input angles for X, Y, and Z rotations. This matrix represents the orientation of the desired machining plane relative to the machine's base coordinate system. A helper function `GET_ROTATION_MATRIX` constructs this matrix by multiplying individual axis rotation matrices. The `TRANSFORM_POINT` function then uses this matrix to convert points defined in the rotated plane's local coordinates into the machine's absolute coordinates. For generating tool paths, the inverse transformation is crucial: `GET_INVERSE_ROTATION_MATRIX` calculates the transpose of the rotation matrix (which is its inverse for orthogonal matrices), allowing points in machine coordinates to be converted back to the rotated plane's local system. The program then demonstrates applying the forward transformation to a sample path and the inverse transformation to a single point. In a real CNC application, the transformed machine coordinates would be used directly in G-code motion commands (G0, G1, G2, G3). This system is fundamental for advanced multi-axis machining.

The `CHECK_COLLISION` program provides a basic collision detection mechanism. It takes the current and target tool positions, the tool's radius, and the workpiece's bounding box as input. The core logic checks if the bounding box of the tool's linear movement path (expanded by the tool's radius) overlaps with the workpiece's bounding box. If there's an overlap in all three axes (X, Y, and Z), it flags a potential collision. This is a highly simplified approach; a robust system would involve more sophisticated geometric checks, such as discretizing the tool path into smaller segments or using swept volume analysis to accurately determine intersection. The algorithm includes a `safe_distance_threshold` to mitigate false positives. If a collision is detected, it prints a warning, moves the tool to a safe emergency stop height, and halts the spindle and program. This macro would typically be called before executing any motion command to ensure safety.
