Metalworking

Speeds and feeds and machined part cost, welding, sheet layout and press brake bending, oxy-fuel cutting, cylinder gases, argon purging and steel fabrication estimating.

Plate layout development

Plate layout at the neutral line for concentric and eccentric cone frustums, square-to-round transitions, mitered elbows and 90° or lateral branch saddles. Dimensioned drawing, ordinate table by division, area, weight and plate size.

Cone, elbow, saddle

Press brake bending

Flat length of parts with several bends from the K-factor (editable table or DIN 6935), natural air-bend radius, material minimum radius, V die opening, minimum flange, tonnage per foot and total, and press brake selection.

K-factor, V die, tonnage

Oxy-fuel cutting

Cutting and preheat oxygen and fuel gas (acetylene, propane or natural gas) use by steel thickness and cut length, speed, cost per foot and per part, and acetylene manifold size from the withdrawal limit, with editable cutting charts.

Gas use, speed, cost

Gas cylinder contents

Contents of oxygen, nitrogen, argon, argon + CO₂ mix, CO₂, dissolved acetylene, hydrogen and helium cylinders in standard cubic feet, pounds and liquid volume, from water capacity, pressure and temperature with compressibility factor Z; duration and cylinders needed for a usage rate.

ft³, lb, liquid, Z factor

Argon back purge

Argon back purge for stainless pipe welding: volume with or without dams, number of volume changes from the exponential dilution model to the target residual O₂, purge time, gas per joint, joints per cylinder and cost.

Time, changes, gas

Speeds and feeds

Pick the operation, tool and ISO 513 material group to load typical cutting speed and feed; compute spindle speed, table feed, removal rate, Kienzle specific cutting force, cutting and motor power, torque and cutting time, checked against machine power.

RPM, feed, power

Machined part cost

Build the quote for a machined part: blank weight from shape and material, chip credit, operation list with cycle time, hour rate and setup spread over the batch, tooling, outside services, scrap, overhead and margin worked out on price.

stock, hours, setup, price

Steel fabrication estimate

Paste the list of shapes, tubes and plate to get the structure weight and build the estimate with cutting waste, welding consumables and gas, painting, hours for cutting, fit-up, welding, finishing and erection, galvanizing, freight, overhead and margin; see the total price and price per pound.

weight, hours, $/lb

Welding cost and filler

Pick the process (stick, MIG/MAG, flux-cored, TIG or submerged arc) and the joint (fillet, single-V, double-V or square) to get weld cross-section, deposited metal, filler from deposition efficiency, welder hours, gas, energy, cost per foot and heat input.

lb/ft, hours, heat input

Also useful

Bar cut list optimizer

Paste the part list (ID, length and quantity) and get the number of stock bars, grouped cutting patterns, kerf and trim loss, usable drops and material weight and cost. Compare up to 4 stock lengths (e.g. 20 ft and 24 ft) and a mixed plan, and use the drops already in stock first.

Bars, patterns and drops

Sheet cut list optimizer

Pick the sheet material (wood, steel, aluminum, glass, plastic) and size, paste the part list (name, length, width, quantity and, optionally, material) and get the number of sheets, a cutting layout for each sheet, yield, offcuts worth keeping, cost and, for wood, edge banding length. Enter the sheets and offcuts you have in stock to use them first, or tick the sizes available, each with its price, and get the cheapest sheet (or mix of sheets) suggested.
