All six run in the browser. Each user gets their own login, and you decide who can open which tool.

Lathe Program Builder

Write a complete lathe program by filling in operations instead of typing G‑code.

For setters and programmers on HAAS gang‑tool lathes.

Request access

Operations: Facing, OD and ID profiles, grooving, threading, drilling and parting off, set up from stock size, clearance and spindle limit.
Output: G71, G75, G76, G83 and G94 canned cycles, or every move written out. Block numbering to suit your shop.
Checks: Stops undercuts that G71 can't cut, chamfers and radii that don't fit their leg, and spindle speeds above the machine's maximum.

Lathe Program Builder with seven operations for an example shaft, its section view and the generated G-code program — The built-in example part: seven operations on the left, the section check and the generated program on the right.

CNC Simulator

Preview a program before it runs on the machine.

For programmers proving code from CAM or written by hand, on lathes and mills.

Request access

Reads: HAAS and Fanuc-style code, and Sinumerik 828D programs with their turning cycles.
Shows: The toolpath in 3D with feeds and rapids separated, a live position readout, and the finished part as a solid.
Warns: Cycles called before a start position is known, grooving steps wider than the tool, and moves with no depth to cut.
Calculates: Cutting speeds and feeds for common shop materials, from free-cutting brass to titanium, in HSS or carbide.

CNC Simulator showing a lathe program, the toolpath over the finished part and a live position readout — The same program in the simulator, part-way through the OD finish pass, with the position, feed and spindle readout above the view.

Feeds & Speeds Calculator

Spindle speed and feed rate for the cut in front of you, with the G‑code lines to paste into the program.

For setters and programmers on lathes and mills, running HAAS, Fanuc-style or Sinumerik controls.

Try the free version Request access

Operations: Turning, milling, drilling and tapping, in HSS or carbide, roughing or finishing.
Materials: Fifteen common shop materials, from plastics and aluminium to stainless, tool steel and titanium, with the starting range for each.
Results: Spindle rpm held to your machine's limit, feed rate, metal removal rate, power and torque, theoretical surface finish and cutting time.
Milling: Feed per tooth raised for chip thinning when the width of cut is under half the cutter diameter.
Output: Speed and feed blocks for HAAS/Fanuc or Sinumerik 828D: G96 with G50 or LIMS, G97, and feed per rev or per minute.

Feeds and Speeds Calculator showing spindle speed, feed rate, power and G-code for roughing stainless 316 — Roughing stainless 316 on a Ø50 bar with carbide: spindle speed, feed rate, power and the G-code lines to paste in.

Spindle Project Management

Jobs, machine time and tooling for a machine shop, in one place.

For shop owners and production managers who need to know where every job stands.

Request access

Jobs: Drop in a drawing PDF and the job is created, with material and stock length read from the drawing.
Time: Start, pause and stop timers per operator and per machine, with a full history on every job.
Tooling: Insert library with codes, grades, suppliers, bin locations, stock levels and photos, shared with Tooling Stock Control.
Inspection: Measuring report PDFs built from the drawing's dimensions, one sheet per unit.
Users: Several people can log in and work on the same jobs.

Spindle dashboard with due jobs, running timers, low tooling stock and the project list grouped by customer — The Today board and project list. Shown with demo data; the customers, parts and operators are placeholders.

Tooling Stock Control

Insert and cutter stock that warns you before the bin runs empty.

For tool crib and production managers who order inserts and need to know where they go.

See the tooling page Request access

Stock: One line per insert or cutter, with grade, bin, pack size, price, supplier and lead time. On hand is the sum of every issue, receipt, return, write-off and count.
Warnings: Lines at or below Min flagged as low, at zero as out, with open orders taken into account.
Ordering: Order quantities that refill to Max in whole packs, and a reorder list PDF grouped by supplier.
Use: Consumption by machine, person, job and reason, breakage share, dead stock and a management report.
Free tool: A reorder point calculator on the tooling page: suggested Min and order quantity for one line.

Tooling Stock Control stock list with low lines on top, bins, on hand, Min and Max, orders and weeks of cover — The stock list, worst first. Shown with demo data; brands, suppliers and people are placeholders.

Setup Sheet Generator

A printable setup sheet for the machine, read from the program itself.

For programmers handing a job to the setter, on lathes and mills running HAAS, Fanuc-style or Sinumerik controls.

See a sample sheet Request access

Reads: The tool list, offsets, work offsets, spindle speeds, feeds, coolant, travel limits and program stops, straight from the G‑code.
You add: Workholding, jaws and grip length, part and tool stick-out, holders and inserts, set-up photos and notes for the setter.
Stick-out: The minimum part stick-out from the jaws and the minimum tool stick-out, from the deepest Z each tool reaches.
First-off: Checks suggested from the program: finished diameters, shoulder lengths, hole depths and threads, with blank columns to record up to five parts.
Output: An A4 PDF to download or print: title block, summary with an estimated cycle time, tools, operation sequence, checks and sign-off boxes.
