設定你的控制器
可直接給控制器使用的 DXF 長什麼樣子、如何一次對應好 Zorocut 在 CypCut 或 FSCUT 中的圖層,以及透過 SheetCAM 的電漿切割流程。
- Export DXF for CypCut and FSCUT: map the layers onceWhat a controller-ready DXF for CypCut, CypCutE and FSCUT looks like — R2000, mm, lines, arcs and circles on fixed layers — and how to map Zorocut's ZC_ layers to CypCut layers once.入門 · 6 分鐘
- CypCut nesting tutorial: the built-in nest step by step, and where it stopsHow to nest parts in CypCut's built-in nest — parts library, plates, part gap, co-edge, arrays and sorting — from the CypCut v6.5 manual, and the limits (50 part types, 20 plates, array only) that tell you when a separate nester pays.套料 · 7 分鐘
- Lead-in and lead-out for laser and plasma: types, length and placementWhy every contour starts with a lead, line or arc, how long (about the plate thickness on plasma near its pierce limit), where to put it, overcut and gap — the CypCut, CypNest, SheetCAM and Hypertherm settings, and why the part spacing must leave room.入門 · 6 分鐘
- Micro-joints and tabs in laser cutting: why, how big and where to put themWhat micro-joints prevent, the sizes shops publish (0.1–1 mm), how CypCut and CypNest add them by click, count, distance or line, where to place them, what removal costs — and why Zorocut leaves them to the controller.入門 · 6 分鐘
- Plasma tables: from Zorocut's DXF to SheetCAM, FireControl, Mach3 or LinuxCNCLangmuir FireControl and other hobby-class plasma controllers run G-code, not DXF. The route is Zorocut DXF → SheetCAM, one operation per layer → post-processor → controller, with Hypertherm chart values for speed and pierce delay.入門 · 6 分鐘

你的第一次乾淨套料
能從 CAD 乾淨匯入的圖面、尺寸正確的單位、零件之間的間距,以及什麼時候共邊切割划算。
- Clean DXF from AutoCAD, Fusion, SolidWorks and Inkscape: what breaks and how to export itOpen contours, splines, bend lines, mirrored arcs and unitless files: the problems each CAD program leaves in a DXF for laser cutting, and the export settings that avoid them.DXF 檔案 · 7 分鐘
- DXF units: mm or inch, and why parts come in 25.4× too big or too smallA DXF stores plain numbers; its unit lives in the $INSUNITS header, which is often 0 or missing. How to spot a unit error before it reaches the quote or the machine, and how to fix it.DXF 檔案 · 5 分鐘
- Open contours in a DXF: why the laser won't cut the part, and how to close themAn open contour has ends that do not meet, so it has no inside and no outside and the controller will not cut it as a part. Where the gaps come from, how to find them, when an auto-join tolerance is safe, and what Zorocut's pre-cut check reports.DXF 檔案 · 6 分鐘
- Cleaning a customer DXF: dimensions, title blocks, bend lines and everything else that must not be cutCustomer files are often drawings, not cut files: dimensions, a frame and title block, notes, bend lines, hidden and centre lines, duplicates and stray points. What each one does at the machine, what Zorocut leaves out by itself, and how to choose the layers that get cut.DXF 檔案 · 7 分鐘
- Splines, polylines and arcs in a DXF: why curves turn into thousands of short linesThe same curve can be an ARC, a polyline bulge, a SPLINE, an ELLIPSE or hundreds of short lines. What each one stores, why true arcs cut better, what CypCut, SheetCAM and Zorocut do with the others, and which export settings keep arcs as arcs.DXF 檔案 · 7 分鐘
- Text in a DXF for laser cutting: cut, mark or engrave — and why TEXT is not cutA DXF TEXT entity stores a string and a font name, not the letter shapes. How to turn text into outlines, when to cut, mark or engrave it, why cut-through letters need bridges or a stencil font, and what Zorocut and CypCut do with text layers.DXF 檔案 · 6 分鐘
- SVG to DXF for laser cutting: sizes, curves, fills and strokes from Inkscape, Illustrator and CorelDRAWVector art becomes a cut file when every shape is a closed path at the right size and text, strokes, clips and images are dealt with. Why SVG sizes come in at 75 % or 133 %, what Zorocut reads from an SVG directly, and what to fix in the art first.DXF 檔案 · 7 分鐘
- Part spacing for laser cutting: how much gap to leave between partsStart with a gap of 3 mm or the sheet thickness, whichever is larger, then adjust for kerf, heat and tip-up. What the spacing does, how the kerf eats into it, and how it changes the quote.套料 · 5 分鐘
- True-shape vs rectangular nesting: what the box around each part costsRectangular nesting packs the box around each part; true-shape nesting packs the real outline. On rectangles they are the same; on brackets, rings and irregular parts the boxes alone capped our test jobs at 60–68 %, while a true-shape nest reached 71–76 %.套料 · 6 分鐘
- Part-in-part nesting: cutting small parts from the holes of large onesPart-in-part nesting cuts small parts from the slugs of large holes. When it pays, how big the hole must be, why the small part is cut first, the heat and tip-up risks, and what CypCut, CypNest and Zorocut do.套料 · 6 分鐘
- Sheet utilisation: how to measure nesting yield and how to raise itUtilisation is the part area divided by the sheet you count as used — whole sheets, used length, or sheets minus the offcut you keep. What the figures mean, why one nest can read 64 % or 80 %, and five ways to raise it.套料 · 6 分鐘
- Common-line cutting: when sharing an edge pays, and why Zorocut leaves it to the controllerCutting two parts along one shared line saves pierces and cut length on arrays of identical straight-edged parts. How CypNest, ProNest and PrimeCut do it, where it is risky, and why the DXF should still keep a gap.套料 · 5 分鐘

速度與穿孔
依材料、厚度與功率區分的起始切割速度,以及為什麼每個穿孔都要花時間和成本。
- Fiber laser cutting speed chart: mild steel, stainless and aluminium by powerPublished fiber laser cutting speeds in m/min at 1 kW, 3 kW and 6 kW from the Raycus and IPG tables, plasma for comparison — and why the charts disagree by up to 2× and you should build your own.速度與材料 · 6 分鐘
- Pierce time by thickness, and why every pierce costs moneyFiber pierce times from 0.1 s on thin sheet to 9 s at 20 mm, plasma pierce delays from the Hypertherm chart, what each pierce adds to a quote, and practical ways to need fewer of them.速度與材料 · 5 分鐘
- Kerf width for fiber laser and plasma: chart by thickness and amperagePlasma kerf from Hypertherm's Powermax cut charts (1.3–3.8 mm), what published sources say about fiber laser kerf, where kerf compensation is set in CypCut, CypNest and SheetCAM, and what the kerf does to part spacing.速度與材料 · 6 分鐘
- Assist gas for fiber laser cutting: oxygen vs nitrogen vs compressed airOxygen for mild steel, nitrogen for clean stainless and aluminium edges, compressed air as the cheap middle: the pressures and speeds in a published 3 kW table, measured nitrogen consumption, what each gas does to the edge, and how to put gas into a quote.速度與材料 · 7 分鐘
- Minimum hole size for laser and plasma cutting, by thicknessThe smallest hole a fiber laser cuts cleanly (half to the full thickness, from SendCutSend and LaserBoost), why plasma holes need one to two times the thickness for bolt quality, and what to tell the customer about smaller holes.速度與材料 · 6 分鐘

為工單報價
機台工時、每公尺與每穿孔的費用,以及套料後剩下的邊料該怎麼處理。
- How to price laser cutting: machine time, per metre and per pierceA laser cutting price is material plus machine time plus a share of setup. The formula, the starting values and a worked example: 100 plates of 3 mm mild steel at €90 an hour come to about €1.02 each.報價 · 7 分鐘
- Laser cutting price per metre, per minute, per hour or per kg: which unit, and how to convertThe five ways shops quote cutting — per machine hour, per minute, per metre plus per pierce, per kg and per part — when each one is fair, the formulas that turn one into another, and one shop's published rates in every unit.報價 · 6 分鐘
- How to work out your laser cutting machine's hourly rateA machine-hour rate is the year's fixed costs divided by the hours you can bill, plus what each hour of cutting uses up: power, gas, consumables and the operator. The inputs with their sources, and a worked example for a 3 kW fiber laser.報價 · 6 分鐘
- How to count pierces and measure cut length from a DXFOne pierce per closed contour — the outline plus every hole — and the cut length is the perimeter of all of them added up. How each DXF entity is measured, what to clean first, what the drawing leaves out, and what Zorocut's DXF checker reports.報價 · 5 分鐘
- How to charge for material in a sheet-metal quoteMaterial is weight × price per kg × markup, and weight is area × thickness × density. Which area to bill — the part's rectangle, its share of the nested sheet or whole sheets — how much shops mark up, and who owns the offcut.報價 · 6 分鐘
- How to price plasma cutting: per inch, per pierce, material and setupHow small plasma shops price: material × 1.25–2, $0.10–0.33 per inch of cut, about $0.15 per pierce, drawing time and a minimum. What an inch and a pierce really cost you, from Hypertherm's cut chart and a consumable kit price, with a worked example.報價 · 7 分鐘
- Laser cutting quote template: what a laser or plasma quote should containThe fields every laser or plasma cutting quote needs — parts, material and thickness, quantity, unit and line prices, setup fee, minimum order, lead time, validity and the assumptions behind the price — with a template, an example and the fees other shops publish.報價 · 6 分鐘
- Remnants: keep, label and reuse sheet-metal offcutsHow to leave a usable offcut instead of scrap, which strips are worth keeping, how to nest the next job on them first, and how to bill the material fairly.套料 · 5 分鐘

名詞解釋
套料與報價的行話,每個詞一句話說清楚。
- 套料(排版)
- 把零件排在板材上,盡可能少用材料。真實外形套料依每個零件的實際輪廓排列,而不是它的外接矩形。
- 零件套零件
- 把小零件放進大零件的孔內,讓孔內的材料變成零件,而不是廢料。
- 零件間距
- 板材上兩個零件之間留下的間隙。Zorocut 以繪製的輪廓之間量測,且絕不讓它變成零。
- 板邊餘量
- 沿板材邊緣保留的空白帶,板邊常常不夠方正,也是夾具夾持的位置。Zorocut 預設從 10 mm 起。
- 割縫
- 光束或電弧去除的材料寬度。電漿割縫較寬(Powermax45 XP 約 1.4–2.1 mm);由控制器或 CAM 補償,而不是 DXF。
- 引入線(引線)
- 從穿孔點到輪廓的一小段路徑,讓穿孔痕跡留在零件之外。在控制器或 CAM 中加入,Zorocut 不會加。
- 微連接
- 一小段不切斷的連接橋,把零件固定在板材上,直到被敲下來。同樣在控制器中加入。
- 穿孔
- 光束或電弧在能切割輪廓之前先打出的孔。每個穿孔都耗時並損耗耗材,所以報價會把它算進去。
- 共邊切割
- 兩個零件共用一條切割邊,只切一次。可以省一刀,但需要小心;Zorocut 把這件事交給控制器的共邊工具。
- 餘料
- 大到值得保留的邊料。標上材料、厚度與尺寸後,下一張同材料的工單會優先把它拿來套料。
- 切割前檢查
- 在 DXF 送到機台前先檢查:開放輪廓、重複線段、單位、微小特徵,以及超出板材的零件。
- 利用率
- 零件佔板材面積的比例。基準測試稱之為密度;實際板材的數字還取決於間距與板邊餘量。
- 控制器
- 機台的控制軟體——CypCut、CypCutE、Phoenix,或 SheetCAM 後面的 G-code 控制器。它匯入 DXF、加入引線,並驅動機台。
- $INSUNITS
- DXF 標頭中說明圖面單位的值。缺少或錯誤時,零件會放大或縮小 25.4 倍。
