CNC加工サイクルタイム短縮方法。加工パラメータの即座のNumber of Passes, Total Cycle Time (min)を取得。
各 seasoned CNC machinist knows that getting the numbers right means the difference between scrap と a perfect part. 溝加工 is no exception. When Gühring application engineers walk a customer through process optimization, this is one of the first parameters they check — because even a 5% error here can cascade into tool failure または out-of-tolerance parts.
ここで働く数式は一見シンプルですが、深い意味を持っています。Korloyは旋削・フライス加工カタログ全体にわたりこのパラメータの参照表を公開しており、IngersollはToolGuideアプリに直接統合しています。基本原理は数十年変わっていませんが、現代のコーティング超硬合金が使用可能範囲を大幅に拡大しました。
Always cross-reference your calculated values against your tool manufacturer's recommended ranges. Gühring's CoroPlus ToolGuide と Korloy's NOVO app provide material-group-specific upper と lower bounds. When in doubt, start conservative — you can always push harder on the second part.
Scenario: Machining 4140 alloy steel (HB 280) on a DMG Mori VMC, using a Gühring solid carbide end mill.
When a slot is wider than the tool diameter, multiple passes are needed. This calculator determines the number of passes and estimates cycle time based on slot width, tool diameter, feed rate, and number of depth steps.
For width ≤ tool diameter, slot in one pass at 50-70% of normal feed rate. For width > tool diameter, multiple passes allow higher feed in each pass and produce straighter slot walls. Never slot at full diameter and full feed -- the 180 deg engagement overloads the tool.
For roughing wide slots: trochoidal or adaptive clearing (especially in hard materials). For finishing: contour passes with 0.1-0.2 mm radial stock. Avoid plunging directly into the slot -- ramp or helix entry reduces impact on the tool centre.
Down-milling (climb milling) produces better surface finish and lower cutting forces. However, in a full slot, both up and down occur simultaneously (one side climbs, the other side conventional mills). For wide slots with multiple passes, use climb milling on each pass.
Enter the slot width, tool diameter, feed rate, and number of Z-level passes. The calculator shows how many lateral passes are needed and estimates the total machining time for the slot. For deep slots, also use the peck drilling calculator for drilling before slotting.
