機械加工の切削条件、商売の利益計算、そして日常の関数計算。 仕事に必要なすべての計算を、これ一つのアプリで完結させます。 ただ計算するだけではありません。「現場で本当に使いやすい」を追求し、徹底的にロジックを作り込んだ、プロフェッショナルのための「万能計算機」です。 【主な機能とこだわり】 ■ 1. MC加工・切削計算モード(現場仕様) マシニングセンタやNC旋盤のオペレーター必須の機能を搭載。一方的な計算だけでなく、現場で頻発する「逆算・検算」に完全対応しました。 完全双方向リンク (n ⇔ Vc): 径(D)と速度(Vc)から回転数(n)を算出するのはもちろん、回転数を手動修正した際に「今の径でVcはいくつになるか?」を即座に逆算表示します。 送り速度の安全確認 (vf ⇔ fz): 送り(vf)を手動で下げた際、一刃送り(fz)がいくらになるかをリアルタイムで逆算。刃物の破損リスクを瞬時に判断できます。 ドリル・タップ完全対応: ドリルの基本である「2枚刃(Z=2)」をデフォルト設定に。タップ加工時はピッチ(P)優先で送りを自動固定します。 材質プリセット: アルミ、鉄(S45C)、SUS、樹脂、チタンの推奨切削速度をワンタップで呼び出し可能。 ■ 2. 商売・利益計算モード 「原価」「売価」「粗利率」のうち、わかっている2つを入力するだけで、残りの1つを瞬時に算出します。 利益額の表示: 利益率(%)だけでなく、「で、結局いくら儲かるの?」という実際の利益額(円)も同時に表示します。 直感シミュレーション: 「原価1,000円の商品を30%の利益で売りたい」「2,000円で売りたいが原価はいくらに抑えるべきか?」といった計算が一瞬で完了します。 ■ 3. 関数・RPN・カメラスキャン 関数電卓: sin, cos, √ などの基本関数を搭載。 RPNモード: 技術者に愛される「逆ポーランド記法」への切り替えが可能。 カメラスキャン: 手書きの数式や図面の数値をカメラで読み取り、そのまま計算機に入力できます。 ■ その他の特徴 計算履歴の表示(スクロール確認可能) 直感的な操作感とハプティックフィードバック 多機能かつ、快適な操作 いちいち電卓を叩き直すのが面倒、条件を変更したときの再計算を楽にしたい。 そんな現場の悩みを解決するために作られた、至高の計算ツールです。ぜひあなたのポケットに入れて、現場へ連れて行ってください。
