G71 CNC Lathe Stock Removal Rough Turning Canned Cycle
G71 is a 2-line canned cycle for CNC turning that automatically generates multi-pass longitudinal roughing toolpaths from a simple profile definition, drastically reducing program length.
G41, G42 & G40 Cutter Radius Compensation CNC Programming
G41 (cutter left) and G42 (cutter right) shift the toolpath automatically by the radius stored in the tool geometry register (D-offset), allowing programmed part contours to remain independent of cutter size.
G00 Rapid vs G01 Linear Feed Interpolation Programming
G00 commands non-cutting rapid positioning at the machine maximum traverse rate, while G01 commands controlled linear interpolation at a specified feed rate (F) for cutting.
Deep Hole Gun Drilling: Straightness & L/D > 50:1 Ratios
Gun drilling is a deep-hole machining process utilizing a single straight-flute cutter with high-pressure internal through-tool coolant (up to 100 bar) to produce straight, high-precision holes.
Thread Milling vs Tapping: CNC Programming & Applications
Thread milling uses a rotating multi-tooth or single-point thread mill interpolating along a 3D helical path (G02/G03 + Z) to machine precise internal and external threads with full pitch control.
Precision Surface Grinding: Sub-Micron Flatness & Finishes
Precision surface grinding utilizes high-speed abrasive wheels composed of aluminum oxide, silicon carbide, or CBN to achieve sub-micron flatness, parallelism, and mirror-grade surface finishes.
Swiss-Type CNC Lathe Machining: Micro Long-Shaft Precision
Swiss-type CNC turning utilizes a sliding headstock and guide bushing where cutting tools engage the stock right at the support point, eliminating bar deflection for ultra-high aspect ratio precision parts.
Sinker EDM (Die-Sinking EDM): Blind Cavities & Sharp Corners
Sinker EDM (Ram EDM) utilizes custom-machined 3D graphite or copper electrodes immersed in dielectric hydrocarbon fluid to spark-erode complex blind cavities, sharp internal corners, and deep ribs.
4-Axis CNC Rotary Milling: A-Axis Setup & Continuous Contouring
4-axis CNC milling integrates a precision rotary table (A-axis or B-axis) into a standard 3-axis platform, allowing continuous cylindrical machining and multi-angle indexing in a single setup.
